IoT Gateway and OPC UA Limitations
Two questions with details written below:
1) Is an OPC UA client able to write to PERS arrays?
2) Is an OPC UA client able to write negative values to an analog input/output?
I can successfully communicate with an IRC5 robot controller utilizing OPC UA and IoT Gateway. I understand that only (TASK) PERS parameters in the RAPID are accessible and I am able to read/write values. I am able to read array values but I am unable to write array values.
In addition, I can read/write IO signals (configured as access level all) with a strange limitation. Analog inputs/outputs (ai/ao) configured to allow negative values are unable to be written to with a negative value from the OPC UA client. It can write positive values as well as read a negative ai/ao value from the controller.
