  Информационные материалы

  The central plant clocks evaluate the clock time data that was transmitted from the wireless receiver and generate diverse output signals in order to synchronize the connected I/O devices.

  If the wireless receiver fails or signal transmission is interrupted, the central plant clocks switch over to their internal high-precision quartz system and thus ensure reliable tracking of the clock time. When the input signal is available again, the central plant clock adjusts any time differences that may have occurred without time jumps by means of "microsteps".

  

  SICLOCK TC100 and SICLOCK TC400 central plant clocks

  Inputs and outputs

  The high-precision SICLOCK TC100 and SICLOCK TC400 central plant clocks have one (SICLOCK TC100) or two (SICLOCK TC400) inputs for connection to wireless receivers.

  The central plant clocks have one (SICLOCK TC100) or four (SICLOCK TC400) independent 10/100 Mbit Ethernet interfaces.

  The network stations are synchronized using the proven SNTP standard and by means of the SIMATIC procedure.

  The SICLOCK central plant clocks have two relay outputs for signaling alarms or warnings.

  Alternatively and/or in addition, two point-to-point connections TTY (20 mA current interface) or one RS 422 (5 V level) connection can be set up for the SICLOCK TC400 central plant clock.

  Operation

  Parameterization of the interfaces, setting of the signal types, redundancy modes, and read-out of the status messages stored in the device are conveniently implemented via the integrated web interface.

  LEDs and a display indicate operating states and show any error messages, which can also be read out via the web interface.

  Note:

  In order to use the comfort-parameterization , you have to use a personal computer with the software Java Runtime V1.4.0 or later version from Oracle. This software is not included in the scope of delivery, but has to be acquired separately, which may incur additional cost.
