I have Quantum PLC with 486 controller communicating to PC from Modbus com1 to PC com1 running ProWorx NxT software, from Modbus com2 thru RTU to Siemens drives, and also to PC on com2 running Wonderware software. The problem I have when I try to use laptop, which has only one com port, I have no communication, the OS and software are same on laptop and desktop.
Any help is apprecitiated.
Thanks,
Danny
