F.3.2 Judging the MP2100M Slave CPU Synchronous Status
F.3.2 Judging the MP2100M Slave CPU Synchronous Status
The method for judging the status of slave CPU synchronization from the application program is as follows.
(1) Method for Checking with the Application at the Master Device
Check bit 7 "SYNC" at the second word "Slave status" (IW+1) of the I/O registers allocated to the
MP2100M.
bit 7
SYNC
If SYNC = ON, it indicates that the slave CPU synchronous status is in effect.
(2) Method for Checking with the Application at a Slave Device
Check bit 7 "SYNC" at the second word "Slave status" (IW+1) of the I/O registers allocated to the local
station.
bit 7
SYNC
If SYNC = ON, it indicates that the slave CPU synchronous status is in effect.
