The GSV (get system value) instruction in RSLogix 5000 can retrieve the status of the communication or I/O modules. 

The required parameters for GSV are:

  • class name
  • module instance name
  • module name in the I/O configuration
  • attribute name
  • fault code
  • dest
  • tag for the variable to put the module status code

If the module status code is non - 0, then the module is not present or is in error.
