	In the opinion of management of Rockwell Automation, Inc. (the Company or Rockwell Automation), the unaudited Condensed 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, 2013. The results of operations for the three and six month periods ended March 31, 2014 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.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Derivative Instruments and Fair Value Measurement	'
	Derivative Instruments and Fair Value Measurement
	We use foreign currency forward exchange contracts to manage certain foreign currency risks. We enter into these contracts to hedge our exposure to foreign currency exchange rate variability in the expected future cash flows associated with certain third-party and intercompany transactions denominated in foreign currencies expected to occur within the next two years (cash flow hedges). Certain of our locations have assets and liabilities denominated in currencies other than their functional currencies resulting from intercompany loans and other transactions with third parties denominated in foreign currencies. We also enter into foreign currency forward exchange contracts that we do not designate as hedging instruments to offset the transaction gains or losses associated with some of these assets and liabilities.
	We value our forward exchange contracts using a market approach. We use a valuation model based on inputs including forward and spot prices for currency and interest rate curves. We did not change our valuation techniques during the six months ended March 31, 2014. The notional values of our forward exchange contracts outstanding at March 31, 2014 were $885.5 million, of which $638.5 million were designated as cash flow hedges. Currency pairs (buy/sell) comprising the most significant contract notional values were United States dollar (USD)/euro, USD/Canadian dollar, Swiss franc/euro, Mexican peso/USD, USD/Brazilian real, Singapore dollar/USD, and Swiss franc/Canadian dollar.
	We also use foreign currency denominated debt obligations to hedge portions of our net investments in non-U.S. subsidiaries. The currency effects of the debt obligations are reflected in accumulated other comprehensive loss within shareholders’ equity where they offset gains and losses recorded on our net investments globally. At March 31, 2014 we had $14.9 million of foreign currency denominated debt designated as net investment hedges.
	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.
	Assets and liabilities measured at fair value on a recurring basis and their location in our Condensed Consolidated Balance Sheet were (in millions):

	Approximately $3.2 million ($2.6 million net of tax) of net unrealized losses on cash flow hedges as of March 31, 2014 will be reclassified into earnings during the next 12 months. We expect that these net unrealized losses will be offset when the hedged items are recognized in earnings.
	The pre-tax amount of gains (losses) reclassified from accumulated other comprehensive loss into the Condensed Consolidated Statement of Operations related to derivative forward exchange contracts designated as cash flow hedges, which offset the related (losses) gains on the hedged items during the periods presented, was:

We base the fair value of long-term debt upon quoted market prices for the same or similar issues.

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.
	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. Currently there are a few thousand claimants in lawsuits that name us as defendants, together with hundreds of other companies. In some cases, the claims involve products from divested businesses, and we are indemnified for most of the costs. However, we have agreed to defend and indemnify asbestos claims associated with products manufactured or sold by our former Dodge mechanical and Reliance Electric motors and motor repair services businesses prior to their divestiture by us, which occurred on January 31, 2007. We are also responsible for half of the costs and liabilities associated with asbestos cases against the former Rockwell International Corporation’s (RIC’s) divested measurement and flow control business. 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.
	We have maintained insurance coverage that we believe covers indemnity and defense costs, over and above self-insured retentions, for claims arising from our former Allen-Bradley subsidiary. Our insurance carrier entered into a cost share agreement with us to pay the substantial majority of future defense and indemnity costs for Allen-Bradley asbestos claims. We believe that this arrangement will continue to provide coverage for Allen-Bradley asbestos claims throughout the remaining life of the 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 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.
	In connection with the spin-offs of our former automotive component systems business, semiconductor systems business and Rockwell Collins avionics and communications business, the spun-off companies have agreed to indemnify us for substantially all contingent liabilities related to the respective businesses, including environmental and intellectual property matters.
	In connection with the sale of our Dodge mechanical and Reliance Electric motors and motor repair services businesses, we agreed to indemnify Baldor Electric Company for costs and damages related to certain legal, legacy environmental and asbestos matters of these businesses arising before January 31, 2007, for which the maximum exposure would be capped at the amount received for the sale.
	In many countries we provide a limited intellectual property indemnity as part of our terms and conditions of sale. We also at times provide limited intellectual property indemnities in other contracts with third parties, such as contracts concerning the development and manufacture of our products. As of March 31, 2014, 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 operating results, financial position or cash flows; 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 results of operations or cash flows in a particular period.

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 or extraordinary items and items that are reported net of their related tax effects. We record the tax effect of significant unusual or extraordinary items and items that are reported net of their tax effects in the period in which they occur.
	The effective tax rate was 27.4 percent in the three and six months ended March 31, 2014, compared to 22.5 percent and 24.1 percent in the three and six months ended March 31, 2013, respectively. The effective tax rate was lower than the U.S. statutory rate of 35 percent in each period primarily because we benefited from lower non-U.S. tax rates.
	The amount of gross unrecognized tax benefits was $42.5 million and $40.8 million at March 31, 2014 and September 30, 2013, respectively, of which the entire amount would reduce our effective tax rate if recognized.
	Accrued interest and penalties related to unrecognized tax benefits were $9.8 million and $12.4 million at March 31, 2014 and September 30, 2013, respectively. We recognize interest and penalties related to unrecognized tax benefits in the income tax provision.
	If the unrecognized tax benefits were recognized, the net reduction of our income tax provision, including the recognition of interest and penalties and offsetting tax assets, would be $26.4 million as of March 31, 2014.
	There was no material change in the amount of unrecognized tax benefits in the six months ended March 31, 2014. We believe it is reasonably possible that the amount of gross unrecognized tax benefits could be reduced by up to $32.3 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.
	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 2010 and are no longer subject to state, local and foreign income tax examinations for years before 2003.

	Among other considerations, we evaluate performance and allocate resources based upon segment operating earnings before income taxes, interest expense, costs related to corporate offices, non-operating pension costs, certain nonrecurring corporate initiatives, gains and losses from the disposition of businesses and purchase accounting depreciation and amortization. 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 using a methodology consistent with the expected benefit.

Product warranty obligations	'
	We record a liability for product warranty obligations at the time of sale to a customer based upon historical warranty experience. Most of our products are covered under a warranty period that runs for twelve months from either the date of sale or installation. We also record a liability for specific warranty matters when they become probable and reasonably estimable. Our product warranty obligations are included in other current liabilities in the Condensed Consolidated Balance Sheet.
Derivative instruments and fair value measurement	'
	We use foreign currency forward exchange contracts to manage certain foreign currency risks. We enter into these contracts to hedge our exposure to foreign currency exchange rate variability in the expected future cash flows associated with certain third-party and intercompany transactions denominated in foreign currencies expected to occur within the next two years (cash flow hedges). Certain of our locations have assets and liabilities denominated in currencies other than their functional currencies resulting from intercompany loans and other transactions with third parties denominated in foreign currencies. We also enter into foreign currency forward exchange contracts that we do not designate as hedging instruments to offset the transaction gains or losses associated with some of these assets and liabilities.
	We value our forward exchange contracts using a market approach. We use a valuation model based on inputs including forward and spot prices for currency and interest rate curves. We did not change our valuation techniques during the six months ended March 31, 2014. The notional values of our forward exchange contracts outstanding at March 31, 2014 were $885.5 million, of which $638.5 million were designated as cash flow hedges. Currency pairs (buy/sell) comprising the most significant contract notional values were United States dollar (USD)/euro, USD/Canadian dollar, Swiss franc/euro, Mexican peso/USD, USD/Brazilian real, Singapore dollar/USD, and Swiss franc/Canadian dollar.
	We also use foreign currency denominated debt obligations to hedge portions of our net investments in non-U.S. subsidiaries. The currency effects of the debt obligations are reflected in accumulated other comprehensive loss within shareholders’ equity where they offset gains and losses recorded on our net investments globally. At March 31, 2014 we had $14.9 million of foreign currency denominated debt designated as net investment hedges.
	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.
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 or extraordinary items and items that are reported net of their related tax effects.
