7.1 Function
A slave CPU synchronous function synchronizes the master side high-speed scan cycle with the MP2300S high-speed
scan cycle, in a configuration where another MP2300S series controller acts as a MECHATROLINK master and the
MP2300S with a built-in SVB acts as a MECHATROLINK slave.
This function automatically allows you the synchronization among slave CPUs and the distribution of application pro-
grams by connecting multiple MP2300Ss as a slave.
The following figure shows a schematic diagram of the slave CPU synchronous function of MECHATROLINK-II.
Here, there is a communication delay in MECHATROLINK-II as shown above, until a command from a master side
application program is transmitted to a slave.
Since, the delay time is constant, you can use an application program to manage the timing between the master and
slave. Note that you don’t need to control the timing between slave CPUs.
„ Caution
A precaution is given to safely use the slave CPU synchronous function.
For more information on the precautions, refer to
7.4 Precautions.
