Modbus Read Node Error

Help
2

Hello Sivasankari,

Thank you for the post. I have listed two suggestions below that you can try to resolve this error.

  1. In the Modbus: Read Node, you currently have the Timeout Template set to 60. This field is in milliseconds. The default value when this field is empty is 30 seconds. You can try clearing this value so the default is 30 seconds and then once you get it working you can lower this number to the appropriate value.
  2. Your screenshot from your terminal output shows a uid of 1. In your workflow, the Modbus: Read Node has a Unit ID Template configured for 0. Try changing this Unit ID Template from a 0 to a 1. Here is more information on Unit ID when using Modbus TCP with the Modbus: Read Node.

Thank you Sivasankari,
Kevin
