The lack of a specific FDSI document for serial-to-Allen-Bradley (aka "DF1" in A-B parlance) makes me wonder if this configuration (i.e., what you are trying to do) is even supported at version 8.2. They have FDSI documents for serial and TCP Modbus, Ethernet/IP (A-B ControlLogix), and OPC Client -- but not for DF1. Might your FBM231 be trying to speak Modbus? If so, and if you don't have something like a Prosoft card in the 5/40, it won't work.

So, result is that communication is still not happen b/w PLC and I/A. Our Settings are as, .XML File Mode: RS232 Baud Rate: 9600 Parity: None Stop Bits: 1 DataBits: 8 Driver: DHPlus/CRC and DIP Switch settings at CAM is Sequence as per FDSI Driver AB DH+ Protocol User's Guide (DI700BD Rev C Page 22) 01 01111 00 000 010 11 0111 10 and we configure the ECB202 for FBM231 and ECB201 for Port. ECB202: Name: PLC00A DEV_ID: PLC00A HWTYPE: 231 SWTYPE: 231 PORTEX: 1 FILEID: DH_PORT.XML SFILEID: ABDRIVER.ZIPH ECB201 NAME: PLC001 DEV_ID: PLC001 HWTYPE: 231 SWTYPE: 231 PARENT: PLC00A DVNAME: MA=2;BA=2 DVOPTS: CAM PORTNO: 1 AND in DCI blocks we configure the IOM_ID: PLC001. we also configure the DIP switches at TCA of FBM231 as A2,A4,A6,A8,B4,B8,C1 ARE closed and reamining are open. we also tried other DIP switch settings too. Does any one know where is error in the configuration Thanks and Best Regards, Imran Butt, System Engineer. _______________________________________________________________________ This mailing list is neither sponsored nor endorsed by Invensys Process Systems (formerly The Foxboro Company).
