Specifications of the Real Time Clock
Resolution: 1 ms
Tolerance: <1 minute / month (+20°C [68°F])
<±1ms if synchronized via IRIG-B
Time Synchronisation Tolerances
The different protocols for time synchronisation vary in their accuracy:
Used Protocol Time drift over one month Deviation to time generator
Without time synchronization <1 min (+20°C) Time drifts
IRIG-B Dependent on the time drift of
the time generator
<±1 ms
SNTP Dependent on the time drift of
the time generator
<±1 ms, if network connection is GOOD (see
operation status of SNTP)
IEC60870-5-103 Dependent on the time drift of
the time generator
<±1 ms
Modbus TCP Dependent on the time drift of
the time generator
Dependent on the network load
Modbus RTU Dependent on the time drift of
the time generator
<±1 ms
DNP3 TCP Dependent on the time drift of
the time generator
Dependent on the network load
DNP3 UDP Dependent on the time drift of
the time generator
Dependent on the network load
DNP3 RTU Dependent on the time drift of
the time generator
<±1 ms
Synchronization over device
Protection Communication
Dependent on the time drift of
the time generator
Depend on the used synchronization protocol
applied on other device.
Additional deviation <±0.2 ms
