Data Refresh Timing; Data Synchronization - YASKAWA 264IF-01 User Manual

5.3.2 Data Refresh Timing

The data refresh timing of the MP2000 Series Machine Controller and EtherCAT transmission lines is shown below.
EtherCAT transmission line

MP2000 Series Machine Controller ↔ 264IF-01 Module
Data is refreshed in the timing of the scan setting of I/O allocation in the detailed definitions window of the
264IF-01 Module.

EtherCAT Transmission Lines ↔ 264IF-01 Module
Data is refreshed in the timing of the EtherCAT communication cycle.
Sandwiching a communications IC, operations between an MP2000 Series Machine Controller and 264IF-01 Module,
and between EtherCAT communication lines and the 264IF-01 Module, are asynchronous.

5.3.3 Data Synchronization

The synchronization of data between an MP2000 Series Machine Controller and EtherCAT transmission lines is guar-
anteed.
