5.4.2 Commissioning the SICLOCK TM/TS
Overview of commissioning tasks
The table below shows the commissioning tasks that are needed to operate the SICLOCK
TM/TS as a central plant clock for time synchronization in a PCS 7 plant:
Step What?
1 Wire the time receiver to the SICLOCK TM/TS
2 Parameterize the time receiver
3 Assign parameters to the SICLOCK TM/TS (SIMATIC or NTP mode)
4 Connect the SICLOCK TM/TS to the PCS 7 plant
By way of example, the following sections provide the most important settings for the
configuration in a PCS 7 plant where the automation systems are synchronized using
SIMATIC mode.
Note
Siclock Remote parameterization software
You can use the "Siclock Remote" parameterization software to make the settings for the
SICLOCK TM and SICLOCK TS central plant clocks. This software is available on the
Internet together with a set of parameter assignment instructions: http://www.siemens-
edm.de (

Assigning parameters to the SICLOCK TM/TS for SIMATIC mode
Make the following settings directly on the SICLOCK TM/TS:
1. Call the parameters of the SICLOCK TM/TS.
2. Set the parameter 338/6A Ethernet to "On."
3. Select an unassigned IP address on your plant bus and configure this at parameter
343/6A of the SICLOCK TM/TS.
4. Make the additional settings according to the following table:
Parameter Value
341/6A "Source addr. part 0" <MAC address>
342/6A "Source addr. part 1" <MAC address>
339/6A "LAN connection"
350/6B "Addr. 1 protocol" "Layer 2 - S5"
351/6B "Send addr. 1" "Each second"
353/6B "Addr. 1 dest. 0" "FFFFFF"
354/6B "Addr. 1 dest. 1" "FFFFFF"
338/6A "Ethernet" "On" or "synchronized"
