REMote Test Mode (All Processors)
The REM Test mode allows you to:
•
Monitor the current ladder program as it is being executed.
•
Save a processor file to disk.
•
Use the search function.
•
Force inputs and set up outputs.
•
Monitor and edit data files.
•
Run your program with output points disabled.
•
Perform SLC 5/03 and SLC 5/04 online edits.
While you are in the REM Test mode, the processor scans or executes the ladder
program, monitors input devices, and updates the output data files without
energizing output circuits or devices. You can perform the following ladder
program tests.
•
Single Step Test (SRG) — This test mode applies to SLC 5/02, SLC 5/03 and
SLC 5/04 processors. Use this test to verify proper ladder operation and for
troubleshooting purposes. Single Step Test initiates the processor to scan and
execute a single rung or group of rungs. Refer to the Instruction Set Reference
Manual for additional information on this feature.
•
Single Scan (SSN) — In this test mode, the processor executes a single
operating cycle that reads the inputs, executes the ladder program, and updates
all data without energizing output circuits.
•
Continuous Scan (CSN) — This test mode is the same as the REMote Run
mode, except output circuits are not energized. This allows you to troubleshoot
or test your ladder program without energizing external output devices.
