MXOPC IO items
Hello,
Setup:
NI LV2014 with DSC module, Mitsubishi MXOPC, Mitsubishi FX3UC PLC. we are using Mitsubishi MXOPC servers to connect to the I/O of Mitsubishi PLC over OPC interface. I use local shared variables to bind them with the IO items. During normal R/W cycle, I read the shared variable or write to it.
Issue:
I am trying to initialize IO items of a OPC IO Server programmatically so that I can bind shared variables to each of them.
as a workaround, what we have been doing is manually initialize IO items by opening the tree items (as seen in the Image). There are IO items located in all_IO. so once I open the tree item, all works OK.
So far what have I tried is to use Create and Configure IO server Express VI. Unfortunately, this VI is not doing a great job for me as it does not initialize the IO items located inside the IO server.
