Time synchronization
■Time distribution interval setting of the CPU module (Un\G89492)
This setting specifies the interval for distributing the clock time of the CPU module on the same system as the master module
from the master station to device stations.
When the setting is changed, the new setting value is enabled after the interval of the distribution operating with the old setting
value has elapsed. The setting value is distributed once after the distribution interval elapses. If the new setting value needs to
be enabled immediately, stop the distribution and set the value.
• 0000H: 10 s (default)
• 0001H to FFFEH: Send using the set time interval (second).
• FFFFH: Distribution stop
Grandmaster information
The grandmaster status of the own station and MAC address are stored.
■Grandmaster (Un\G89508)
When the own station is the grandmaster, "1" is stored.
• 0: Another station is the grandmaster.
• 1: Own station is the grandmaster.
■Grandmaster MAC address (Un\G89511 to Un\G89513)
The grandmaster MAC address is stored.
• Un\G89511: 5th byte, 6th byte of the MAC address
• Un\G89512: 3rd byte, 4th byte of the MAC address
• Un\G89513: 1st byte, 2nd byte of the MAC address
Time synchronization setting
■PTP frame send source check enable/disable (Un\G89537)
• 0: Do not check
• 1: Check
■PTP frame send source check result (P1) (Un\G89538)
• 0: One send source
• 1: Two or more send sources
