  2. GX PLC RS232 Communication Code

    I have been using Mitsubishi PLCs for the last 17 years and to be honest whenever I need to shift data I generally use an Arduino. But I have existing PLCs that each need to be connected to a PLC running Biometric Readers. The handshake between the PC in a box (running the biometric readers) and the PLC (running an access control turnstile) will be 8 bit ASCII code via RS232 connection. I am struggling to find any working examples of code to run an RS232 BD card on an FX3G PLC, I have set up an FTDI RS232 UART and I can see data coming in from an Arduino but I can't get the FX3g to send any data via RS232. I can't even get the PLC to communicate. Unfortunately the tech support offered here in the UK is awful. Any help would be appreciated. Regards Julian
