Running Ignition 7.6, routing through a control logix chassis:
Ethernet->ENBT: IP=10.1.178.11->Slot6: DH/RIO Card->SLC 5/04 at node 21
I have an OPC-UA Device (Allen Bradley SLC) pointed to 10.1.178.11 with communication path:
I have added ~15 tags that reference both int values and I/O bools in the SLC.
The int tags work just fine, but the boolean tags that point to the input bits fault out in a blinking manner. Half the time the tags work, and are the appropriate value for the physical I/O, but half the time they are bad quality. The blink cycle also seems to be tied to the scan rate: If I increase the scan rate slow time, they blink slower.
When I first set up this device driver, I didn’t see this problem. But then I deleted the driver, and had to re-enter it. Now the tags constantly blink.
