HI,

I get this error: "Gurux.DLMS.AMI.Agent.Worker.GXAgentWorker[0] Failed to establish the connection. Value cannot be null. (Parameter 'PortName')" after connecting the agent and adding a new task. The connection is successful but once a task is added, it throws the error above.

Thanks for your help.

Hi,

I believe that you try to communicate with serial port. This error occurs because your serial port is not selected in the agent settings.

Thank you.

Could you please provide guidance on where/how I can set the serial port in the agent settings?

Hi,

Select the agent and select the serial port that you want to use with the agent.
GXDLMSDirector has set the correct serial port settings and those will be used.
