Program the Packaged Controller Chapter 5
Controller Fault Handler programs, Power-up Handler programs, unscheduled
programs, or unscheduled equipment phases.
RSLogix 5000 software indicates if you are trying to exceed the 16-program
limit when you attempt to add another program after the 16th. The indicator is
that you are unable to select New Program from the task’s menu (that is, New
Program is dimmed).
Add a Program or Equipment Phase
To add a program or equipment phase, right-click the task you want to add the
program to and choose New Program or New Equipment Phase.
Then specify your program or equipment phase properties.
For more information about developing and implementing your packaged
controller program, see the Logix5000 Controllers Common Procedures
Programming Manual, publication
1756-PM001 .
Trends
Trends let you view sampled tag data over a period of time on a graphical
display. Tag data is sampled by the controller and then displayed as points on a
trend chart. The CompactLogix packaged controller supports the use of one
trend in your application.
For information about creating and using a trend, see the Logix5000
Controllers Quick Start, publication
1756-QS001 .
Monitoring Controller Status
The CompactLogix 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 with 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.
