You need to use a protocol analyzer application to monitor the RS422 lines. I have a free Win32 Console application that will monitor 2 half duplex lines through one COM port if you want one.

Gmail won't accept these types of files even if they are sent in a zipped (.zip, .tar, .tgz, .taz, .z, .gz) format. If this type of message is sent to your Gmail address, it is bounced back to the sender automatically.

A3B0 error is sub system communication error, the PLC/Slave device is unable to communicate with master device/DCS. You need to check on the PLC side. There is no wrong in DCS side comm.
