Remarks
[2] Precondition of check flow
This check flow describes the countermeasure method (replacement of defective module and
subsequent restoring method) in the event the system running normally so far suddenly breaks down.
Therefore, the following cases are excluded.
1. Trouble due to error in initial setting when starting up the system (system memory, parameter,
setting switch, etc.).
2. Momentary failure due to transient abnormality due to noise or other effect (irreproducible trouble).
3. Trouble due to effect of ladder program (customer's application).
[3] Prepare for causing trouble
1. Be sure to keep back-up for program memory and system memory
When the JW-32CUM1 control module is abnormal, the current program memory and the like may
not be saved by the support tool, or the saved data may be incorrect. Therefore, store the latest
program memory and back-up of system memory always in the floppy disk (FD).
In the case of ROM operation, store the back-up in the FD, too.
2. Prepare for support tool at hand
Prepare the support tool that can load/save of hand-held programmer or program.
3. Prepare for spare parts
Prepare always a spare of each module to be ready for abnormality.
4. Prepare for "setting SW, setting system memory, I/O relay allocation table" of each module
For prompt troubleshooting, prepare the "switch setting table and I/O relay allocation table" of each
module.
*Prepare also the "parameter setting table" in the module which requires setting of parameter aside
from switches, such as special I/O module and option module.
7-7 Troubleshooting
In the event of abnormality on the JW30H (JW-32CUM1), check the LED (RUN, FAULT) of the power
supply module and the JW-32CUM1 (-[1]), and remedy according to the check flow depending on the
state.
As for errors concerning the communication functions (such as the DeviceNet) of the JW-32CUM1, see
"Errors and treatment" of each function.
DeviceNet -8-27, Remote I/O (master station) -9-11
Data link DL1 (master station) -10-14, Data link DL9 (master station) -11-16,
M-net (master station) -12-14.
