ENCS-3 is a reliable software and hardware platform for building remote control systems for substation and power plants. This is proven by a decade of experience operating of previous generation model ENCS-3.
Remote terminal unit (RTU) ENCS-3 is designed to create geographically distributed systems:
— at the field level installed devices (ENIP-2, ENB series) which support measurement parameters values, monitoring digital signals and control by digital outputs to switchgears and mechanism;
— all this devices are connected to RTU ENCS-3 via RS-485 lines or local networks.
RTU ENCS-3 collect, consolidate and distribute necessary data to a higher level of control systems. To control data traffic from field level devices ENCS-3 uses absolute and relative apertures. Timestamps of data are assigned by field devices.
ENCS-3 build on 32bit ARM microcontroller and providing continuous operation for remote control systems. To increase reliability system ENCS-3m support 2 redundant modes: warm standby and hot standby.
ENCS-3 use hard real-time algorithm, and thus provides high performance and reliability.
ENCS-3 polls devices according IEC 60870-5-101. ENCS-3 support up to 10 ports for device polling.
ENCS-3 allows setup up to 16 channels to transmit data to upper level using 2 LAN and RS-232/RS485 ports. 2 RTUs ENCS-3 connect through CAN-bus to support warm standby in pair.
RS-485 interface, RS-232, Ethernet can be distributed by the user between data collection from field devices and transmission of information to the top level.
To communicate with the field devices are preferred protocol IEC 60870-5-101, which provides for the regulation of traffic between the RTU and devices, and allows you to send a data with timestamp directly from the sources of their formation.
