The site has purchased a gas chromatograph (process analyzer) whose modbus interface runs in a Dell PC. I want to poll their Modbus slave via RS232 from DeltaV Serial port.
The vendor obtained a card from Amazon . . . so far no luck with communication. Anyone have good experience with an aftermarket PC card?
