F.3.6 Managing Restarting of MP2100M Slave CPU Synchronization
Slave CPU synchronization processing is executed automatically whenever the execution conditions are all satis-
fied.
When this happens, the following operations are performed by the system in the status of transition between the
slave CPU asynchronous status and the slave CPU synchronous status.
• Adjustment of scan cycle start timing at the slave side
• If an SVB-01 or SVC-01 Module is mounted at the slave side, resetting MECHATROLINK communi-
As a result of these operations there are the following effects on the operation of the application at the slave
devices.
• There is one scan with a cycle longer than the set time.
• If operation was being performed with the
• Communication with MPE720 temporarily stops (communication restarts on transition to the slave
If you wish to avoid these effects (if you wish to avoid automatic restoration of the slave CPU synchronous sta-
tus) due to the nature of the application, operate the control bit "SLVSC (slave CPU synchronization restart con-
trol)" in the application at the slave side.
By operating this bit you can control the execution of synchronization processing.
