I have an application where I am trying to communicate from GE 90-70 PLC using the IC697CMM711 module to an FES COMNET Gateway. I have proven the communication between Micro III controller and FES COMNET gateway using HyperTerminal, so I have proven the addresses of the devices and that communication is active. I used the code given by PLC manual to communicate with FES gateway and found that the code related to attach command (7202 number) works but the code related to read command doesn't work. I am getting 01 data in status register when I used attach command for communication which means successful operation. However I am getting the error (370C H code) in status register when I try to read from FES gateway. I am not getting any data from the compressor control panel because of this error. If any ideas, or suggestions would be helpful. Thanks in advance.
