System with GPS reception
SICLOCK TC400 central plant clock with SICLOCK GPS1000 wireless receiver
The SICLOCK GPS1000 wireless receiver (Article No.
2XV9450-1AR84) is used in this example. The wireless receiver
is mounted outdoors with "visual contact" to the navigation satel-
lites for optimum reception quality.
The line current method (TTY - 20 mA) used in the SICLOCK sys-
tem permits distances of up to one kilometer between the wire-
less receiver and the central plant clock and also supplies the
receiver with power, which eliminates the need for any additional
power supply components. This makes it possible to install the
central plant clock at a central location, even in plants spread
over a very large area.
The SICLOCK TC400 central plant clock shown in the example
features four 10/100 Mbit Ethernet interfaces for supplying up to
four independent IP networks. The SICLOCK TC100 central
plant clock with one Ethernet interface has been designed for
smaller, cost-sensitive plants.
The central plant clocks do not have Ethernet switching
functionality for safety reasons. SIMATIC NET SCALANCE X
switches are recommended for this purpose, see
133200
