6.6.2
Applicable Versions and Execution Conditions
Applicable Versions
To use slave CPU synchronization, the SVC Function Module in both the master and slave must
support slave CPU synchronization. The applicable versions are given in the following tables.

Execution Conditions
To use slave CPU synchronization, the execution conditions must be met in both the master
and slave. If the conditions are not met, the MP3000 Controllers will operate without synchro-
nizing the high-speed scan cycles between the master and slave.
Master
• The CPU Unit/CPU Module must be version 1.06 or later.
• The high-speed scan setting must be an integer multiple of or an integer fraction of 1 of the
MECHATROLINK transmission cycle setting.
Slave
• The CPU Unit/CPU Module must be version 1.06 or later.
• The CPU Unit/CPU Module hardware must support slave CPU synchronization.
• The high-speed scan setting must be an integer multiple of or an integer fraction of 1 of the
MECHATROLINK transmission cycle setting.
• The high-speed scan setting must be an integer multiple of or an integer fraction of 1 of the
high-speed scan setting in the master.
• Slave synchronization must be enabled in the MECHATROLINK Communications Definition
Dialog Box.
• The SLVSC (Slave CPU Synchronization Restart Control) command control bit in the output
registers must be set to OFF.
