Determine if Communication Has Timed Out with a Specific
I/O Module
If communication times out with a device (module) in the I/O
configuration of the controller, the controller produces a fault code for
the module.
• The GSV instruction gets the fault code for Io_Module and stores
it in the Module_Status tag.
• If Module_Status is any value other than 4, the controller is not
communicating with the module.
