Im having a bit of trouble trying to figure this out any assistance is greatly appreciated...
Im using a Rockwell L32E compact logix controller with a Prosoft MVI69-MCM modbus module.
I have the plc set as a master polling up to 50 slaves. I have a poll interval of 1 second per command, a error retry of 3, error timeout 1 second.
The problem I have is when several slaves are powered down the comms slows right down 4 seconds per powered down slave (1 sec time out 3 retries)
I believe I can use a special function block 3000 to disable polling these devices.
Question is how do I use this 3000. I confused as to how to actually go about using it.
Thanks in advance
Mike
