I am looking at an application which would use our
embedded controller board with an Allen-Bradly PLC-2/x PLC. The controller board has serial ports (RS-232/RS-485) that would communicate with the PLC via the DF-1 protocol. The controller board also has a 10 MB/s Ethernet port which will communicate with the factory LAN.
The PLC ladder logic program will have to be unique for each machine that this device is used with since different people want different data collected and monitored. Maybe the ladder logic
program would not need to modified if I can just
read the correct memory location (for monitoring
variables) and output it via the DF1 interface port.
Has anyone done something like this using the DF1 protocol using the older PLC-2/x AB PLCs? Anyone see any major issues with this application?
Thanks,
David
