IOEXC Example​


Example: The steps to use the IOEXC instruction are as follows:

  1. If M0.0 is energized, the IOEXC instruction sets 1 to have the module at H0105 replaced.

  1. Take the module off the chassis and replace it.
  2. If there is no error, continue. Otherwise, double check everything was removed and replaced correctly.
  3. Turn off M0.0 and complete the replacement.
