The Path attribute is available with Logix Designer application, version 24.00.00
and later. This attribute provides a communication path to the module.
For more information on the attributes available in the MODULE object, see the
Logix 5000 Controllers General Instructions Reference Manual, publication
1756-RM003 .
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.
