Hi,
I'm pretty new at this but completed my first control job here recently and everything worked fine. I was programming for a CompactLogix PLC and I used RSLogix5000 to do the logic. Most of my code used program-scoped tags but I used a few controller-scoped tags so that a couple tasks could share them.
The automation guy at the plant said he wanted to do the HMI and tie in the new PLC to their network. So, of course I let him. Now he says he cannot access the program-scoped tags over the network and wants me to change them all to controller-scoped.
He is using an ethernet connection to the PLC. Is this correct that he will not be able to access these program-scoped tags via their network? Can anyone explain why? Or if it's not true, what needs to be done to access them?
Thanks
John
