TCP I/O FAQs

Q: Why is my device not responding to the TCP commands?

Complete the following steps to ensure that your device is configured correctly:

  1. Verify that your device is connected to the network.
  2. If your device is a master device (initiates communication), verify that the device is defined as a master TCP/IP device in the Communication Device Manager and that the TCP server is running.
  3. If your device is a slave device (receives communication), verify that the device is defined as a slave TCP/IP device in the Communication Device Manager and that the IP Address and TCP Port are correct.

Q: Why are commands not executed when I click the step in the State Configuration window?

In Configuration mode, commands are executed only when you click one of the following buttons:

  • Run Inspection Once
  • Run Inspection in Loop
  • Run Inspection until Failure

Vision Builder AI does not execute the step when you click on the step to avoid potential timeouts associated with the step.
