3-2-12 Normal Slave Table - Omron CJ1W-DRM21 Operation Manual

3-2-12 Normal Slave Table

This table indicates the slaves that are communicating normally with the master. Bits 00 to 63 of
LWORD-type device variable for CJ-series Unit *_NormSlavTblSta correspond to slaves at node
addresses 0 to 63.
For all set I/O connections, the bits corresponding to slaves that successfully established connection
will be TRUE.
If connection is not yet established due to a network error, etc., the applicable slave bit turns FALSE.
These are not flags to show the remote I/O communications status.
This table is updated continuously.
However, in the case of a communications power supply error, Send Timeout Error or remote I/O com-
munications stopped (including remote I/O communications stopped due to a communications error), all
bits turn FALSE.
The following device variable for CJ-series Unit is used to reference all information of the Normal Slave
Table.
