Fixed Cycle Communication; Synchronous Communication Function - Mitsubishi Electric MELSEC-Q Series User Manual

This chapter explains the network functions of the Simple Motion module.

8.1 Fixed Cycle Communication

The communication cycle of the Simple Motion module is fixed cycle. The communication is
performed with slave modules in a cycle set in the operation cycle setting.

8.2 Synchronous Communication Function

A slave module which supports the synchronous communication function operates
synchronously with the operation cycle of the Simple Motion module (the communication
cycle of CC-Link IE Field Network). Therefore, the operation timing between the Simple
Motion module and each slave module can be synchronized.
A slave module which does not support the synchronous communication function is also
connectable. However, the operation is not synchronized with the operation cycle of the
Simple Motion module. Therefore, the operation timing of the slave module is not
synchronized with the Simple Motion module.
