Time Synchronization - Mitsubishi Electric MELSEC iQ-R Series User Manual

Time synchronization

This synchronizes the time of device stations with the time synchronization source (CPU module of the master station).
No.0
Setting method
The time synchronization is set with the buffer memory. ( Page 219 Time synchronization)
Set the same time zone and daylight savings time to the CPU modules of the master and local stations.
When setting the Motion module as the master station, do not connect time synchronization devices with time
synchronization priority of 0 to 15.
The priority is a value assigned to time synchronization devices from devices within the network to determine
the grandmaster. The priority increases as the value decreases.
For the priority verification method and setting method, refer to the manual of the time synchronization device.
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 or RJ71GN11-T2s 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.
• The WinCPU module cannot use this function.
