C200HE com help

[Juan C. 0]

Guys I need some help! I no little to nothing about Omron but here is what is going on. I have 7 C200's & they all link through a CLK-21 comm card. My problem is we pulled 3 omron drives that also linked with this system. At this point I can't find a fault or a thing stopping me from running but the Main PLC will not allow me to start my convayer. What step should I take now! Thanks

were the drives running the conveyor... were the drives communicting on the CLK (controller link network) as well... could be a nuumber of different things... you have really only given us a small amount of info..
