Example of time synchronization
It is assumed that all SINAUT nodes in the network need to be synchronized.
Figure 1-12 Example of time synchronization: Network section 1 - MPI / classic WAN
● ST7cc
No settings are necessary here.
● Master TIM 4R / master TIM 4RD
Time synchronization on the MPI bus must be enabled for both TIMs. An interval of 1
minute is recommended.
Note
ST7cc and ST7sc expect time synchronization on the MPI bus at intervals of 1 minute or
less. Longer intervals cause error messages.
In this example, the "master TIM 4RD" takes over the master function after startup
because it has a DCF77 receiver. Once this TIM has received a valid time of day, the
ST7cc PC and the "master TIM 4R" are synchronized over MPI. If the TIM with a DCF77
receiver fails, the "master TIM 4R" can take over the master function.
