5.12.2 How to configure time synchronization on a PCS 7 system with redundant bus
system
Overview of configuration steps
The table below shows the steps that are necessary for configuring time synchronization for
redundant buses, including references to the sections in this documentation that provide a
corresponding description:
Step What? For further information, refer to
the section:
1 Commission the SICLOCK "Commissioning the SICLOCK
TC 400 (Page
60)"
"
Commissioning the SICLOCK
TM/TS (Page 64)"
2 Connect the GPS decoder to SICLOCK and configure it "Commissioning GPS receivers
(Page 66)"
3 If the central plant clock is a SICLOCK TM/TS:
Parameterize the DCF 77 reception service on the domain
controller
• Installing and configuring "DCF 77 reception service
for Windows"
• Port/interface: COM1 or COM2
• Time Base: Local Time
"Commissioning the DCF 77
receiver (Page 69)"
4 Connect the SICLOCK to the plant bus, depending on the
configuration selected:
• Via Ethernet for high-availability redundant buses
• Via SCALANCE for separated plant buses
