What RSLogix 5000 function will indicate whether a Prosoft module is present and functioning in the ControlLogix chassis?

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.
