Hi all,
I'm just programming my first Control Logix PLC and I could do with a little advice, please.
The CPU communicates through its RS232 port with RS Logix 5000 without a problem. However, I need to attach an HMI screen to this port (a ProFace GP2500 screen, in fact).
The problem is that RS Logix uses RS Linx to communicate using the DF1 protocol, set as DF1 point to point (with 19200, 8,1,none) serial, and the screen seems to need DF1 Slave mode using 19200,8,1,even serial settings.
I can change the controller serial options in RSLogix OK, but as soon as I do, RSLogix loses comms with the CPU, then nothing much seems to work.
Any suggestions would be greatly appreciated,
Regards,
