[foxboro] FBM230 Communication with AB PLC5 over DH+

Hi list,
I am working on integration of Allen Bradley PLC5 with Foxboro I/A version 8.3 
over AB DH+ protocol. I have installed an FBM230 with FCP270 and configured 
ECB200 and EC201 as parent and child ECB. I am using AB 1770 KF2 interface unit 
between PLC5 and Foxboro I/A FBM230. Port-1 of FBM230 is used for serial 
communication. For parent and child ECBs I first configured ECB200 and then and 
ECB201 for CAM and then an ECB201 for PLC5. The communication between the PLC5 
and FBM230 via 1770 KF2 has been established and I can see the CAM and PLC5 
online on SMDH. I have configured a DCI block PAKIN to read PLC5 integer 
register e.g. N23:26/S2 (S2 is used to read 16 bit signed integer) and made 
proper connection to iom_id parameter e.g. 04CP01_ECB:WTP_01  (where WTP_01) is 
ECB201 for PLC5 but I am unable to get data from PLC5. As seen in block detail 
display, all data bits in the DCI block are in cyan color means no data is not 
being retrieved from PLC5. I also checked PLC5 configuration for data 
read/write previliges and found to be configured as Read/Write. Do anyone have 
any idea of the problem?
 
Rgds,
Ali Ahmed Zahidi
