I have a project to upgrade an old 1756-L55 to a newer CPU. The customer wants added functionality and the old CPU is limited to RSL v16.
The only caveat is the line has an existing HMI they prefer to keep that uses the DF-1 serial port and the -L7x's and -L8x's don't. It's a proprietary HMI written in Delphi by the OEM that won't come off the source code and recreating it would be involved, especially as the customer doesn't want any changes in text or graphics as the operators are "used to this".
I have been unable to find a DF-1/RS232 IO card for this. There is DH485 & DH/RIO cards, but they don't support DF-1 - or at least I have not found it in any of the manuals I downloaded from RA.
Does anyone know of an aftermarket RS232 IO card for the CLX, or have a way to do this?
