Timesync

An important part of any automated control system is a time sync system. Time synchronisation is needed for any devices, servers and user workstations

Time synchronization must be performed with an accuracy of:
- no worse than ±5 seconds per day in automated electricity metering systems;
- from 1 to 1000 ms in automated substation control systems.
This is necessary to record the timestamps of events (changes in the state of switching devices, protection and automation triggering signals, etc.).
Higher time synchronization accuracy requirements are imposed on devices included in digital substations and wide area monitoring system (WAPS) – no worse than 1 μs per day.

Time sync module ENCS-2 serves as the precise time server in automated control systems: using the antenna ENCS-2 receives data from GLONASS/GPS satellites and synchronizes devices via PTP and SNTP protocols. ENCS-2 can simultaneously synchronize time via other interfaces: RS-485-1 and RS-232 (IEC 60870-5-101, NMEA), and RS-485-2 (IRIG-A, IRIG-B, PPS).
