The NSJ Troubleshooter enables troubleshooting errors that have occurred in
the Controller Section or DeviceNet Section. Refer to 10-2 NSJ Trouble-
shooter Function for the actual procedures.
The Ladder Monitor function can be used to monitor the execution status of
the ladder program in the Controller Section or in the CPU Unit of another
PLC.
Refer to SECTION 9 Ladder Monitor for details.
The PLC Data Trace function uses the data trace function in the Controller
Section of an NSJ Controller and displays the results of the data trace on the
Display Section.
After receiving the data trace execution command from the Display Section,
the Controller Section establishes the specified trigger condition, reads the
specified bit status according to the sampling conditions, and stores the sam-
pled data in the Controller Section's Trace Memory.
The Display Section reads the data stored in the Controller Section and dis-
plays that data on the screen as a time chart.
The PLC Data Trace function can be used in NSJ12, NSJ10, and NSJ8 Con-
trollers with Display Section system version 6.6 or higher.
