Hi All,
Has anyone managed to get Modbus comms to work using MS VPC running on XP. I have set up a virtual win95 machine and the problem is whenever I try a talk to a Modicom Quantum using MB Modsoft just jumps back to main screen. If i unhook PLC I get the expected error 199 fault.
It looks like a timing issue (Suprise) but cannot get a fix sorted.
Thanks
