Major Function

- Adaptable to various input and output : DI, DO, AI, AO, Pulse, Timer, PID, and Logic Point, etc.
- Performing multi functions : watch, control, measurement, synchronization of standard time, alarm management, message management, and high speed network communication function
- Sequential control and loop control function
- Supporting various protocol (Harris 6000, DNP 3.0. Modbus, etc.) 

Characteristics of the System

 - On-the-spot trouble diagnosis, and maintenance and repair are possible and easy.
 - Online watch of all sorts of operational data. 
 - Using the same time as in the control post by dint of the function of synchronization of standard time.
 - Change and maintenance and repair are easy by dint of plug-in-type circuit design. 

Application 

 - Remote watch control system
 - Whole automatic system of a transformer substation
 - Water management and environment watch control system 
 - All sorts of industry including traffic signal watch and control system
