Configuring the SICLOCK TC 400
1. Connect the SICLOCK TC 400 to the network.
(For example, connect Ethernet port ETH1 of the SICLOCK TC 400 to the terminal bus)
2. Open Internet Explorer on a PC. Enter the network address of the SICLOCK TC 400 in
the input field (e.g. Port:ETH1 = address 192.168.1.10).
3. In the configuration portal area, click the "SICLOCK TC 400 configuration tool" link.
The configuration tool opens.
4. Select Data Transfer > Download parameters from device from the configuration tool
menu.
5. Configure the SICLOCK TC 400 in accordance with the table below.
Note
The identifier "= ..." in the "Parameters and setting" column represents the "plant-specific
setting".

entry
Network settings e.g. Port: Ethernet 1 (ETH1)
• IP adapter 1 / IP address = ...
• IP adapter 1 / subnet mask = ...
Enter the plant-specific network
address(es). Configure the network
connections ETH2, ETH3 and ETH4 in
the same way.
SIMATIC mode e.g. Port: Ethernet 2 (ETH2)
• Mode = PCS 7-compatible mode, every 10 seconds
• Send condition = "No condition"
• Target address = "FF:FF:FF:FF:FF:FF"
SIMATIC mode is available at all four
Ethernet ports.
Note: Only activate SIMATIC mode for
the ETHERNET ports on the plant bus.
A synchronization time of 10 seconds is
recommended for PCS 7.
A broadcast telegram is sent to all nodes
on this network.
NTP server NTP server
• Operation = On
• Mode = 10 s
• Multicast address = ...
The NTP server is available at all four
Ethernet ports. Requirements:
SICLOCK TC 400 is synchronized.
Multicast address: Enter the plant-
specific IP address for NTP time
synchronization.
Display Display:

• Language setting:
German or English
• Time base:
Local time, UTC or atomic time (TAI)
Select the time that will appear on the
