5.4 Commissioning a central plant clock
5.4.1 Commissioning the SICLOCK TC 400
Requirement
To configure the SICLOCK TC 400, the Java runtime software is required. Only install the
Java runtime software for accessing the SICLOCK TC 400 on an engineering station or a
separate PC station (not on components that are involved in process mode).
The Java runtime software is supplied on a CD together with the SICLOCK TC 400.
Overview of configuration steps
The table below shows the configuration steps that are needed to operate the
SICLOCK TC 400 as a clock for time synchronization of a PCS 7 plant:
Step What?
1 Wire the time receiver to the SICLOCK TC 400
2 Parameterize the time receiver
3 Set the basic parameters on the SICLOCK TC 400
4 Connect the SICLOCK TC 400 to the PCS 7 plant
5 Configure the SICLOCK TC 400 on a plant-specific basis via Internet Explorer
By way of example, the following sections list the most important settings for configuration in
a PCS 7 plant:
● In the examples below, the central plant clock SICLOCK TC 400 receives a time signal
via a GPS radio clock.
● The terminal bus (port: ETH1) and plant bus (port: ETH2) are synchronized directly using
the central plant clock SICLOCK TC 400.
