Dear Emerson Support
We have recently upgraded to Emerson AMS Device Manager 14.5.
I noticed that on one station, where we have MTL4850 multiplexer installed, it can find the multiplexers and our valves connected to multiplexer. But when we double click multiplexer or any valve, we receive the following error immediately.
DEVICE SCREEN ACCESS
FAILED TO CONTACT DEVICE. PLEASE CHECK DEVICE CONNECTION
funny thing is that not only i can see the multiplexer, but i can also see the valves connected to it. But nothing can be opened. I tested the MUX with the MUX Test facility given in AMS Installation package and it seems to be responding fine. Can you please help me with this issue.
