7.3.2 How to Determine Slave CPU Synchronous State
The way to determine the slave CPU synchronous state from an application program is as follows:
( 1 ) How to Check with a Master Side Application
Use bit 7 “SYNC” of the second word “Slave Status” (IW + 1) of an input register assigned to MP2300S.
If SYNC = ON, it is in a slave CPU synchronous state.
( 2 ) How to Check with a Slave Side Application
Use bit7 “SYNC” of the second word “Slave Status” (IW + 1) of an input register assigned to a local station.
If SYNC = ON, it is in a slave CPU synchronous state.
