Configuration
4.14 Time-of-day synchronization
TIM 1531 IRC
88 Operating Instructions, 02/2018, C79000-G8976-C468-02
Before configuring time-of-day synchronization specify the following:
● Specify the time source in the network.
● Specify the time master in the network.
● Specify the network via which the time of day will be forwarded by the time master to the
time slaves.
Configuring the synchronization via Ethernet
Time master
1. In the parameter group "Receive time" of the TIM to be time master configure the time
source with one of the following options:
– From NTP server
– From local station
(take the time from the assigned CPU)
– Receive time from WAN
(take the time from a network)
2. Configure the interface of the TIM via which time messages will be forwarded in the
parameter group "WAN settings" as network type "Master station".
The function is supported for the Ethernet interface with the MSC protocol and for the
serial interface with the setting "network type" = "Neutral".
3. In the parameter group "Send time" for the interface from step 2 enable the option
"Forward time to WAN".
Via the connected network the time messages are forwarded in the network.
4. If necessary, enable the "To local station" option in the "Send time" parameter group if the
assigned CPU should also be synchronized.
1. Configure the interfaces of the other TIM modules that will be time slaves in the
parameter group "WAN settings" as network node type "Node station" or "Station".
The function is supported for the Ethernet interface with the MSC protocol and for the
serial interface with the setting "network type" = "Neutral".
2. Network the interfaces of the TIM modules involved with each other and with the interface
of the time master.
3. For the stations set the parameters of time-of-day synchronization in the parameter group
"Receive time".
4. If necessary, enable the "To local station" option in the "Send time" parameter group if the
assigned CPU should also be synchronized.
