( 3 ) Synchronization between Modules
[ a ] Overview
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 Modules,
can be enabled.
When synchronized mode is used, the start of the high-speed scan and the various communication cycles are
synchronized. 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.
[ b ] 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.
[ c ] Timing At Which Modules Are Synchronized
Modules are automatically synchronized when the power supply is turned OFF and ON again.
