Accounting Policies [Abstract]
Basis of Presentation and Accounting Policies	Basis of Presentation and Accounting Policies In the opinion of management of Rockwell Automation, Inc. ("Rockwell Automation" or "the Company"), the unaudited Consolidated Financial Statements contain all adjustments necessary to present fairly the financial position, results of operations, and cash flows for the periods presented and, except as otherwise indicated, such adjustments consist only of those of a normal, recurring nature. These statements should be read in conjunction with our Annual Report on Form 10-K for the fiscal year ended September 30, 2021. The results of operations for the three and six months ended March 31, 2022, are not necessarily indicative of the results for the full year. All date references to years and quarters herein refer to our fiscal year and fiscal quarter, unless otherwise stated. Receivables We record an allowance for doubtful accounts based on customer-specific analysis and general matters such as current assessments of past due balances and economic conditions. Receivables are stated net of an allowance for doubtful accounts of $14.0 million at March 31, 2022, and $13.2 million at September 30, 2021. In addition, receivables are recorded net of an allowance for certain customer returns, rebates and incentives of $9.2 million at March 31, 2022, and $6.7 million at September 30, 2021. The changes to our allowance for doubtful accounts during the three and six months ended March 31, 2022, were not material and primarily consisted of current-period provisions, write-offs charged against the allowance, recoveries collected, and foreign currency translation. Earnings Per Share The following table reconciles basic and diluted earnings per share (EPS) amounts (in millions, except per share amounts): Three Months Ended Six Months Ended 2022 2021 2022 2021 Net income attributable to Rockwell Automation, Inc. $ 53.9 $ 415.0 $ 295.4 $ 1,008.3 Less: Allocation to participating securities (0.1) (0.9) (0.8) (1.6) Net income available to common shareowners $ 53.8 $ 414.1 $ 294.6 $ 1,006.7 Basic weighted average outstanding shares 116.2 116.1 116.1 116.1 Effect of dilutive securities Stock options 0.9 0.9 1.0 0.9 Performance shares — 0.1 0.1 0.1 Diluted weighted average outstanding shares 117.1 117.1 117.2 117.1 Earnings per share: Basic $ 0.46 $ 3.57 $ 2.54 $ 8.67 Diluted $ 0.46 $ 3.54 $ 2.51 $ 8.59 For each of the three and six months ended March 31, 2022, there were 0.3 million shares related to share-based compensation awards that were excluded from the diluted EPS calculation because they were antidilutive. For each of the three and six months ended March 31, 2021, there were 0.2 million shares related to share-based compensation awards that were excluded from the diluted EPS calculation because they were antidilutive. Non-Cash Investing and Financing Activities Capital expenditures of $8.1 million and $15.5 million were accrued within Accounts payable and Other current liabilities at March 31, 2022, and 2021, respectively. At March 31, 2022, there were no outstanding common stock share repurchases recorded in Accounts payable. At March 31, 2021, there were $2.8 million of outstanding common stock share repurchases recorded in Accounts payable that did not settle until the next fiscal quarter. These non-cash investing and financing activities have been excluded from cash used for capital expenditures and treasury stock purchases in the Consolidated Statement of Cash Flows. Recently Adopted Accounting Pronouncements In June 2016, the FASB issued a new standard that requires companies to utilize a current expected credit losses impairment (CECL) model for certain financial assets, including trade and other receivables. The CECL model requires that estimated expected credit losses, including allowance for doubtful accounts, consider a broader range of information such as economic conditions and expected changes in market conditions. We adopted the new standard as of October 1, 2020. The adoption of this standard did not have a material impact on our Consolidated Financial Statements.

Revenue Recognition

Revenue Recognition	6 Months Ended
	Mar. 31, 2022
Revenue from Contract with Customer [Abstract]
Revenue Recognition	Revenue Recognition Nature of Products and Services Substantially all of our revenue is from contracts with customers. We recognize revenue as promised products are transferred to, or services are performed for, customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those products and services. Our offerings consist of industrial automation and information products, solutions, and services. Our products include hardware, software, and configured-to-order products. Our solutions include custom-engineered systems and software. Our services include customer technical support and repair, asset management and optimization consulting, and training. Also included in our services is a portion of revenue related to spare parts that are managed within our services offering. Our operations are comprised of the Intelligent Devices segment, Software & Control segment, and Lifecycle Services segment. Revenue from the Intelligent Devices and Software & Control segments is predominantly comprised of product sales, which are recognized at a point in time. The Software & Control segment also contains revenue from software products which may be recognized over time if certain criteria are met. Revenue from the Lifecycle Services segment is predominantly comprised of solutions and services, which are primarily recognized over time. See Note 15 for more information. Unfulfilled Performance Obligations As of March 31, 2022, we expect to recognize approximately $845 million of revenue in future periods from unfulfilled performance obligations from existing contracts with customers. We expect to recognize revenue of approximately $460 million from our remaining performance obligations over the next 12 months with the remaining balance recognized thereafter. We have applied the practical expedient to exclude the value of remaining performance obligations for (i) contracts with an original term of one year or less and (ii) contracts for which we recognize revenue in proportion to the amount we have the right to invoice for services performed. The amounts above also do not include the impact of contract renewal options that are unexercised as of March 31, 2022. Disaggregation of Revenue The following tables present our revenue disaggregation by geographic region for our three operating segments (in millions). We attribute sales to the geographic regions based on the country of destination.

Below is a summary of our Contract liabilities balance (in millions): March 31, 2022 March 31, 2021 Balance as of beginning of fiscal year $ 462.5 $ 325.3 Balance as of end of period 541.0 393.1 The most significant changes in our Contract liabilities balance during the six months ended March 31, 2022, were due to amounts billed, partially offset by revenue recognized that was included in the Contract liabilities balance at the beginning of the period and revenue recognized on amounts billed during the period. The most significant changes in our Contract liabilities balance during the six months ended March 31, 2021, were due to amounts billed, partially offset by revenue recognized that was included in the Contract liabilities balance at the beginning of the period. In the six months ended March 31, 2022, we recognized revenue of approximately $260.8 million that was included in the Contract liabilities balance at September 30, 2021. In the six months ended March 31, 2021, we recognized revenue of approximately $181.5 million that was included in the Contract liabilities balance at September 30, 2020. We did not have a material amount of revenue recognized in the six months ended March 31, 2022, and 2021, from performance obligations satisfied or partially satisfied in previous periods.

Business Combination and Asset Acquisition [Abstract]
Acquisitions	Acquisitions Fiscal 2022 Acquisitions In November 2021, we acquired AVATA, a services provider for supply chain management, enterprise resource planning, and enterprise performance management solutions. We assigned the full amount of goodwill related to this acquisition to our Lifecycle Services segment. In March 2022, we, through our Sensia affiliate, acquired Swinton Technology, a provider of metering supervisory systems and measurement expertise in the Oil & Gas industry. We assigned the full amount of goodwill related to this acquisition to our Lifecycle Services segment. Fiscal 2021 Acquisitions Plex acquisition In August 2021, we acquired Plex Systems, a cloud-native smart manufacturing platform. Plex offers a single-instance, multi-tenant Software-as-a-Service manufacturing platform operating at scale, including advanced manufacturing execution systems, quality, and supply chain management capabilities. We recorded assets acquired and liabilities assumed in connection with this acquisition based on their estimated fair values as of the acquisition date of August 31, 2021. The preliminary aggregate purchase price allocation is as follows (in millions): Purchase Price Allocation Accounts receivable $ 14.8 All other assets 28.4 Goodwill 1,728.2 Intangible assets 531.4 Total assets acquired 2,302.8 Less: Contract liabilities (29.2) Less: Other liabilities assumed (32.8) Less: Deferred income taxes (35.3) Net assets acquired $ 2,205.5 Purchase Consideration Total purchase consideration, net of cash acquired $ 2,205.5 Intangible assets identified include $276.4 million of customer relationships, $232.8 million of technology, and $22.2 million of trade names (approximately 12-year weighted average useful life). We assigned the full amount of goodwill and all other assets acquired to our Software & Control segment. The goodwill recorded represents intangible assets that do not qualify for separate recognition. This goodwill arises because the purchase price for Plex reflects a number of factors including the future earnings and cash flow potential of the business, the strategic fit and resulting synergies from the complementary portfolio of leading software-as-a-service applications, industry expertise, and market access. We do not expect the goodwill to be deductible for tax purposes. The intangible assets were valued using an income approach, specifically the relief from royalty method and multi-period excess earnings method. The relief from royalty method calculates value based on hypothetical payments that would be saved by owning an asset rather than licensing it. The multi-period excess earnings method is the isolation of cash flows from a single intangible asset and measures fair value by discounting them to present value. These values are considered level 3 measurements under the U.S. GAAP fair value hierarchy. The key assumption requiring the use of judgement in the valuation of the customer relationship intangible asset was the customer attrition rate of 5 percent; other assumptions included forecasted cash flows attributable to the existing customers and the discount rate. The key assumptions requiring the use of judgement in the valuation of the technology intangible asset were the royalty rate of 25 percent and the obsolescence factor estimating a phase out over 10 years; other assumptions included forecasted revenue growth rates and the discount rate. The allocation of the purchase price to identifiable assets above is based on the preliminary valuations performed to determine the fair value of the net assets as of the acquisition date. The measurement period for the valuation of net assets acquired ends as soon as information on the facts and circumstances that existed as of the acquisition date becomes available, but not to exceed 12 months following the acquisition date. Adjustments in purchase price allocations may require a change in the amounts allocated to net assets acquired during the periods in which the adjustments are determined. Other acquisitions In October 2020, we acquired Oylo, a privately held industrial cybersecurity services provider based in Barcelona, Spain. We assigned the full amount of goodwill related to this acquisition to our Lifecycle Services segment. In December 2020, we acquired Fiix Inc., a privately held, artificial intelligence enabled computerized maintenance management system (CMMS) company based in Toronto, Ontario, Canada. We assigned the full amount of goodwill related to this acquisition to our Software & Control segment. We recorded assets acquired and liabilities assumed in connection with these acquisitions based on their estimated fair values as of the respective acquisition dates. The aggregate purchase price allocation for these acquisitions is as follows (in millions): Purchase Price Allocation Accounts receivable $ 6.0 All other assets 15.9 Goodwill 224.8 Intangible assets 69.6 Total assets acquired 316.3 Less: Liabilities assumed (25.5) Less: Deferred income taxes (3.7) Net assets acquired $ 287.1 Purchase Consideration Total purchase consideration, net of cash acquired $ 287.1 Intangible assets identified include $69.6 million of customer relationships, technology, and trade names (approximately 11-year weighted average useful life). We assigned $12.8 million of goodwill to our Lifecycle Services segment and $212.0 million of goodwill to our Software & Control segment, which represents intangible assets that do not qualify for separate recognition. We do not expect the goodwill to be deductible for tax purposes. Total sales from the fiscal 2021 acquisitions and acquisition-related costs recognized in the three and six months ended March 31, 2021, were not material. Pro forma consolidated sales for the three and six months ended March 31, 2021, were approximately $1.8 billion and $3.4 billion, respectively, and the impact on earnings is not material. The preceding pro forma consolidated financial results of operations are as if all of preceding fiscal 2021 acquisitions occurred on October 1, 2020. The pro forma information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved had the transaction occurred as of that time.

Equity Securities Equity securities (level 1) consist of 10,571,340 and 10,582,010 shares of PTC Inc. ("PTC") common stock (the "PTC Shares") at March 31, 2022, and September 30, 2021, respectively. The PTC Shares are classified as level 1 in the fair value hierarchy, as described below, and are recognized at fair value in the Consolidated Balance Sheet using the most recent closing price of PTC common stock quoted on Nasdaq. Equity securities (other) consist of various securities that do not have a readily determinable fair value which we account for using the measurement alternative under U.S. GAAP. These securities are recorded at the investment cost, less impairment, plus or minus observable price changes (in orderly transactions) of an identical or similar investment of the same issuer in the Consolidated Balance Sheet. Observable price changes are classified as level 2 in the fair value hierarchy, as described below. The carrying values at March 31, 2022, and September 30, 2021, include cumulative upward adjustments from observed price changes of $13.8 million and $5.1 million, respectively. We record gains and losses on investments within the Change in fair value of investments line in the Consolidated Statement of Operations. For the three and six months ended March 31, 2022, we recorded losses of $142.0 million and $127.6 million, respectively, related to the PTC Shares. For the three and six months ended March 31, 2021, we recorded gains of $190.9 million and $581.3 million, respectively, related to the PTC Shares. For each of the three and six months ended March 31, 2022, we recorded gains of $8.7 million related to securities without a readily determinable fair value due to observed price changes. There were no such gains or losses for the three and six months ended March 31, 2021. For the three and six months ended March 31, 2022, we also recorded losses of $7.4 million and $14.2 million, respectively, on equity method investments included within Other above. There were no such losses for the three and six months ended March 31, 2021. U.S. GAAP defines fair value as the price that would be received for an asset or paid to transfer a liability (exit price) in an orderly transaction between market participants in the principal or most advantageous market for the asset or liability. U.S. GAAP also classifies the inputs used to measure fair value into the following hierarchy: Level 1: Quoted prices in active markets for identical assets or liabilities. Level 2: Quoted prices in active markets for similar assets or liabilities, quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs other than quoted prices that are observable for the asset or liability. Level 3: Unobservable inputs for the asset or liability. The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while we believe our valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. We did not have any transfers between levels of fair value measurements during the period presented.

In March 2022, we remeasured our U.S. pension plan assets and liabilities in accordance with U.S. GAAP settlement accounting rules and recognized settlement expense of $24.9 million. Settlement accounting was required due to the amount of lump-sum payments made by the U.S. pension plan to retirees and other separated employees. Remeasurement of our U.S. pension plan assets and liabilities reduced our net benefit obligation by $199.2 million. The discount rate used for the remeasurement as of March 31, 2022, was 4.00 percent compared to 3.10 percent at our September 30, 2021, annual measurement date.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingent Liabilities	Commitments and Contingent Liabilities Various lawsuits, claims, and proceedings have been or may be instituted or asserted against us relating to the conduct of our business, including those pertaining to product liability, environmental, safety and health, intellectual property, employment, and contract matters. Although the outcome of litigation cannot be predicted with certainty and some lawsuits, claims, or proceedings may be disposed of unfavorably to us, we believe the disposition of matters that are pending or have been asserted will not have a material effect on our business, financial condition, or results of operations. The following outlines additional background for obligations associated with asbestos, divested businesses, and intellectual property. We (including our subsidiaries) have been named as a defendant in lawsuits alleging personal injury as a result of exposure to asbestos that was used in certain components of our products many years ago, including products from divested businesses for which we have agreed to defend and indemnify claims. Currently there are a few thousand claimants in lawsuits that name us as defendants, together with hundreds of other companies. But in all cases, for those claimants who do show that they worked with our products or products of divested businesses for which we are responsible, we nevertheless believe we have meritorious defenses, in substantial part due to the integrity of the products, the encapsulated nature of any asbestos-containing components, and the lack of any impairing medical condition on the part of many claimants. We defend those cases vigorously. Historically, we have been dismissed from the vast majority of these claims with no payment to claimants. Additionally, we have maintained insurance coverage that includes indemnity and defense costs, over and above self-insured retentions, for many of these claims. We believe these arrangements will provide substantial coverage for future defense and indemnity costs for these asbestos claims throughout the remaining life of asbestos liability. The uncertainties of asbestos claim litigation make it difficult to predict accurately the ultimate outcome of asbestos claims. That uncertainty is increased by the possibility of adverse rulings or new legislation affecting asbestos claim litigation or the settlement process. Subject to these uncertainties and based on our experience defending asbestos claims, we do not believe these lawsuits will have a material effect on our business, financial condition, or results of operations. We have, from time to time, divested certain of our businesses. In connection with these divestitures, certain lawsuits, claims, and proceedings may be instituted or asserted against us related to the period that we owned the businesses, either because we agreed to retain certain liabilities related to these periods or because such liabilities fall upon us by operation of law. In some instances, the divested business has assumed the liabilities; however, it is possible that we might be responsible to satisfy those liabilities if the divested business is unable to do so. We do not believe these liabilities will have a material effect on our business, financial condition, or results of operations. In many countries we provide a limited intellectual property indemnity as part of our terms and conditions of sale and at times in other contracts with third parties. As of March 31, 2022, we were not aware of any material indemnification claims that were probable or reasonably possible of an unfavorable outcome. Historically, claims that have been made under the indemnification agreements have not had a material impact on our business, financial condition, or results of operations; however, to the extent that valid indemnification claims arise in the future, future payments by us could be significant and could have a material adverse effect on our business, financial condition, or results of operations in a particular period. During the first quarter of fiscal 2021, we reached a favorable settlement agreement regarding litigation of a trademark infringement and false advertising matter and received $70 million. The settlement gain is recorded in Other (expense) income in the Consolidated Statement of Operations.

Income Taxes

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes At the end of each interim period, we estimate a base effective tax rate that we expect for the full fiscal year based on our most recent forecast of pre-tax income, permanent book and tax differences, and global tax planning strategies. We use this base rate to provide for income taxes on a year-to-date basis, excluding the effect of significant unusual items and items that are reported net of their related tax effects in the period in which they occur. The effective tax rate was (20.2) percent and 10.9 percent in the three and six months ended March 31, 2022, respectively, compared to 19.2 percent and 17.2 percent in the three and six months ended March 31, 2021, respectively. The effective tax rate was lower than the U.S. statutory rate of 21 percent in the three months ended March 31, 2022, primarily due to PTC investment adjustments and non-U.S. tax rates. The effective tax rate was lower than the U.S. statutory rate of 21 percent in the six months ended March 31, 2022, primarily due to excess income tax benefits of share-based compensation and non-U.S. tax rates. The effective tax rate was lower than the U.S. statutory rate of 21 percent in the three months ended March 31, 2021, primarily due to non-U.S. tax rates. The effective tax rate was lower than the U.S. statutory rate of 21 percent in the six months ended March 31, 2021, primarily due to PTC investment adjustments and non-U.S. tax rates. An income tax liability of $233.7 million and $264.8 million related to the U.S. transition tax under the Tax Cuts and Jobs Act of 2017 (the "Tax Act") that is payable greater than 12 months after March 31, 2022, and September 30, 2021, respectively, is recorded in Other liabilities in the Consolidated Balance Sheet. Unrecognized Tax Benefits The amount of gross unrecognized tax benefits was $4.3 million at both March 31, 2022, and September 30, 2021, of which the entire amount would reduce our effective tax rate if recognized. Accrued interest and penalties related to unrecognized tax benefits were $1.5 million at both March 31, 2022, and September 30, 2021. We recognize interest and penalties related to unrecognized tax benefits in the income tax provision. We believe it is reasonably possible that the amount of gross unrecognized tax benefits could be reduced by up to $3.8 million in the next 12 months as a result of the resolution of tax matters in various global jurisdictions and the lapses of statutes of limitations. If all of the unrecognized tax benefits were recognized, the net reduction to our income tax provision, including the recognition of interest and penalties and offsetting tax assets, could be up to $5.3 million. We conduct business globally and are routinely audited by the various tax jurisdictions in which we operate. We are no longer subject to U.S. federal income tax examinations for years before 2018 and are no longer subject to state, local, and foreign income tax examinations for years before 2014.

Depending on the product, intersegment sales within a single legal entity are either at cost or cost plus a mark-up, which does not necessarily represent a market price. Sales between legal entities are at an appropriate transfer price. We allocate costs related to shared segment operating activities to the segments consistent with the methodology used by management to assess segment performance.

Accounting Policies [Abstract]
Receivables	ReceivablesWe record an allowance for doubtful accounts based on customer-specific analysis and general matters such as current assessments of past due balances and economic conditions. Receivables are stated net of an allowance for doubtful accounts
Recent Adopted Accounting Pronouncements	Recently Adopted Accounting Pronouncements In June 2016, the FASB issued a new standard that requires companies to utilize a current expected credit losses impairment (CECL) model for certain financial assets, including trade and other receivables. The CECL model requires that estimated expected credit losses, including allowance for doubtful accounts, consider a broader range of information such as economic conditions and expected changes in market conditions. We adopted the new standard as of October 1, 2020. The adoption of this standard did not have a material impact on our Consolidated Financial Statements.
Income Taxes	Income TaxesAt the end of each interim period, we estimate a base effective tax rate that we expect for the full fiscal year based on our most recent forecast of pre-tax income, permanent book and tax differences, and global tax planning strategies. We use this base rate to provide for income taxes on a year-to-date basis, excluding the effect of significant unusual items and items that are reported net of their related tax effects in the period in which they occur.
