Specifications and Functions

[ e ] Synchronization between Modules

Overview

MP2300S Machine Controller has 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 syn-
chronized. This means that commands from the high-speed scan will be sent at consistent points in communica-
tion cycle processing and simplifies distribution processing for interpolation commands.

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.
