Hi

I have a compact logix PLC and a PV Plus 7 HMI.
They are all healthy and connected in linx but the PLC will not communicate with the HMI im guessing. No data is being displayed on the HMI, only ????.

Any ideas where to start.

As a side note, in rslinx, when i right click and select module statistics, connection manager, a window pops up stating an unexpected comms error has occured.

edit, i can ping all addresses on the network

Thanks
Tim

Have you set your path inside FactoryTalk to point the screen to the PLC - both runtime and design.

You shouldn't need to go into RS Linx
