Summary of ChangesThe information below summarizes the changes made to this manual since version 1769-UM013B-EN-P (January 2006): DescriptionPage(s)Changed Figures 1.3 and 1.4 to correctly show the wiring of the RJ45 daisy-chained connectors.1-4 and 1-5In the “Compatible Products” section, added the PowerFlex 4M and PowerFlex 40P drives.1-6Moved the Module Start-Up Status Indication table from Chapter 1 to Chapter 2 after the “Applying Power” section.2-15Added the subsection “Special Case—Data Entry for 2 Stop Bits Communication.”3-8Changed module Parameters 15 - [RTU Parity 1], 30 - [RTU Parity 2], and 45 - [RTU Parity 3] per 1769-SM2 firmware v2.001 update. The parameter numbers remain the same but the parameter names changed from [RTU Parity x] to [RTU Format x]. Also, in addition to parity (None, Even or Odd), the parameter function changed to include choice of stop bits (1 or 2).3-17, B-3, B-5, and B-7In the “Using Reference/Feedback” section, revised table to include PowerFlex 4M and PowerFlex 40P drives.4-4Added the new section “Using RSLinx Classic” to Chapter 8.8-2Updated the Logic Command word and Logic Status word information to include data for all PowerFlex 4-Class drives.D-1 and D-2soc-ii  Table of ContentsPrefaceAbout This ManualRelated Documentation . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
