1.1.6 Synchronization between Modules

( 1 ) Overview

MP2200 and MP2300 Machine Controllers have a function that can synchronize hardware between the CPU and an
optional module. This function enables MECHATROLINK communications in synchronization with high-speed scans.
As a result, synchronization between a built-in SVB Module and an SVB-01 Module, or among multiple SVB-01 Mod-
ules, can be enabled.

When synchronized mode is used, the start of the high-speed scan and the various communication cycles are synchro-
nized. This means that commands from the high-speed scan will be sent at consistent points in communication cycle
processing and simplifies distribution processing for interpolation commands.

( 2 ) Conditions Under Which Synchronization Is Possible

The following table shows the combinations of high-speed scan times and MECHATROLINK communication cycles
that allow synchronization between modules in the synchronization mode.

( 3 ) Timing At Which Modules Are Synchronized

Modules are automatically synchronized when the power supply is turned OFF and ON again.
