Writing from virtual controller Profinet signals to PLC through OpcUa

dragolollo

Hello all,

I would like to simulate ProfiNet communication between the virtual controller and Siemens PLC using OpcUa. I have configured the OpcUa client in RobotStudio assigning the ProfiNet device to an array of Usint defined in a DB (an array for the input, another for the output).
If I set the input array in the PLC, then I see the corresponding Profinet signals set as well. But if do the opposite (I set one of the output Profinet signals), I don't see nothing changing in the corresponding array in the PLC. 
What I have noticed is that when I configure the relationship between Profinet output and OpcUa node, I get this error;

Bad result writing OPC UA data for node 2 (status: 2155085824)

Has anyone ever had this kind of issue?

Hello,
I have encountered the same problem. I tried to use different types of arrays in the PLC ocpua node but they cannot be added to the RS opcua configuration.

The solution is to set the Profinet internal device with input and output size of 64 byte (in the tab Controller, Configuration --> I/O System --> Profinet Internal Device). 
You'll get another error ("Unable to write robot input data on device: PN_Internal_Device"), but the communication works.
