Pardon my jumping in here, guys.
I have a question about your system architecture. I want to be sure you’re using groov View/Build and Ignition Edge on the same groov Box. Is that the case?
For example, if you’re using groov Server for Windows on a PC (like our free trial), or a separate groov Box to access the one in question, that will not work.
To be clear, the Ignition Edge license (with OPC UA and MQTT enabled) does not permit external connections to the OPC UA server. Only internal applications on the groov Box are permitted, e.g., groov View/Build, Ignition Edge itself, and Node-RED. This is in addition to the 500 tag limit imposed by the Ignition Edge license. These license limitations are documented.
If you are working with these applications all within the same groov Box and getting these errors, then there is a problem somewhere, and we’ll track it down.
As an aside, if you’re ever curious about whether the PLC communications are working properly with the Ignition OPC UA server on the groov Box, be sure to use the Quick Client capability in the Ignition Edge Gateway Web UI (listed in Configure tab, under OPC Server). The Quick Client is an OPC UA Client built into the gateway interface specifically for testing your device communications. It’s a real time saver.
