Connections Chapter 1
Example:
This rung checks the status of an I/O connection. The controller checks the entry status of the connection; any value other than 4 indicates that the connection is
not functioning correctly. When the controller detects an error, the error code and information is trapped, and the controller tries to re-establish the connection.
