8-6-2 Diagnostic table
The diagnostic table that was specified in the JW-32CUM1 (control section) can be used to check the
communication status of the nodes (master and slave stations). The addresses of the diagnostic tables
(master mode: 256 bytes, slave mode: 128 bytes) are shown below.

Diagnostic data (256 bytes)
Master status (2 bytes)
- The error information and operating status of the master
station is indicated by turning bits ON or OFF.
- See page 8-44.
Communication monitor table (8 bytes)
- The node addresses are numbered 0 to 63.
The communication status of each node is
indicated by turning the bits ON or OFF.
ON: Normal
OFF: Abnormal
- See the next page.
-A bit representing the master station status
will turn OFF when any of the slave stations is abnormal.
Operating status monitor table (8 bytes)
- The node addresses are numbered 0 to 63.
The operating status of each node is
indicated by turning the bits ON or OFF.
ON: The slave station is operating
OFF: The slave station is idle.
- See the 8-41.
- For details about the operating status of slave stations,
see the specifications for each slave station.
Device status table (64 bytes)
- The status of the slave station devices can be monitored
by keeping track of the device status codes assigned to
each node address. 00
(H)
is normal.
- See page 8-42, 43.

the data table allocation system is set to
"fixed allocation."
*3: Do not change any values in the reserved
area. If you do, the JW-32CUM1 will
malfunction.
