Configurations for time synchronization of a PCS 7 plant
3.3 Configurations for time synchronization in a work group
Time synchronization (V7.1)
Function Manual, 03/2009, A5E01216578-01
39
Time synchronization on the plant bus
Configuring the automation systems:
● The automation system with standard CPU (without integrated Ethernet interface) is
configured for operation as a time slave.
● The SIMATIC PCS 7 BOX and SIMATIC PCS 7 AS RTX are configured.
NOTICE
Automation system with integrated Ethernet interface
The use of these CPU types in this PCS 7 configuration and in configurations with a
combined plant and terminal bus is not permitted. These CPU types can only be
synchronized via NTP mode. We recommend using a central plant clock.
