Specifications
Specifications of the Real Time Clock
Resolution: 1 ms
Tolerance: <1 minute / month (+20°C [68°F])
<±1ms if synchronized via IRIG-B
Time Synchronization Tolerances
The different protocols for time synchronization 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
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
