– Clock synchronization
The internal clock has 1ms resolution and a stability of
35ppm in the operational temperature
range.
It can be synchronized with an external time reference in the following ways:
Using the standard “Time Synchronization” procedure of the “IEC870-5-103” protocol.
Using the “MSCom 2” software or from the DCS with the Modbus RTU protocol.
Note
: On power supply failure an internal battery supports the internal clock for over two years.
