Monitoring Controller Status

The ControlLogix controller uses Get System Value (GSV) and Set System Value

(SSV) instructions to get and set (change) controller data. The controller stores

system data in objects. There is no status file, as in the PLC-5 processor.

The GSV instruction retrieves the specified information and places it in the

destination. The SSV instruction sets the specified attribute with data from the

source. Both instructions are available from the Input/Output tab of the

Instruction toolbar.

Figure 39 - GSV and SSV Instructions for Monitoring and Setting Attributes

When you add a GSV/SSV instruction to the program, the object classes, object

names, and attribute names for the instruction are shown. For the GSV

instruction, you can get values for the available attributes. For the SSV

instruction, only the attributes you can set are shown.
