Infrared Comms to PLS

1 post in this topic

I am trying to write a program to communicate with an OMRON PLC (CJ1M series or similar) via the RS232 port using infrared (from a PDA). Questions: Has anyone done this and if so what RS232-infrared adapter was used? Can an iRDA RS232 adapter be used to emulate a serial cable connection (like the Serial Port Profile on bluetooth)? In programming this do I have to use Windows "Sockets" or will it look like a virtual COM port at the PDA application? Eric
