Time Synchronization - Mitsubishi Electric RD78G4 User Manual

Time synchronization

This synchronizes the time of all stations connected to CC-Link IE TSN with the time synchronization source (Motion module
of the master station).
Even if this function is not used, the time of the slave station is always automatically synchronized with the master station.
No.0
Setting method
It is set with the buffer memory. ( Page 90 Time synchronization)
If there is no device with a higher priority than the master station, the CPU modules on the same base
synchronize with the time of the Motion module in the master station, which becomes the time synchronization
source.
For the priority verification method and setting method, refer to the manual of the time synchronization device.
If "Connection Device Information" of "Basic Settings" is set as "Authentication Class B Only", use a CC-Link
IE TSN-compatible switching hub certified by the CC-Link Partner Association. A slave station connected to
an industrial switching hub that is not compatible with CC-Link IE TSN cannot perform data link.
Precautions
• If this function is used, the time setting function (SNTP client) of the Ethernet-equipped module cannot be used. (
MELSEC iQ-R Ethernet User's Manual (Application))
• If multiple Motion modules are mounted to a CPU module on the same base, set time synchronization for only one Motion
module. If time synchronization is set for multiple, they are overwritten by the time that is synchronized later.
• When using the multiple CPU system configuration, the CPU module No.1 becomes the time synchronization source.
