How to Use the GSV and SSV Instructions in Studio 5000 and RSLogix 5000

This tutorial will provide an in-depth look at the GSV (Get System Value) instruction in Rockwell Studio 5000 (formerly known as RSLogix 5000). The SSV (Set System Value) will also be discussed. GSV and SSV basics will be reviewed (the concept of GSV and SSV Objects, the need for scan time consideration). Several programming examples will be shown (looking for the presence of forces, determining module fault status, and getting date and time).
