Is there anybody out there who was successful in seting up a serial link between CitectSCADA 6.1 and a Modbus PLC using a USB to RS233 converter?
I have no problem setting up the comms using the built in COM1, but I need another COM port (USB-to-RS232) to do the same. Is it at all possible? Any help will be greatly appreciated.
