IEC 61131 Controller, Straton IDE, VPN router, built-in I/Os

Z-TWS4-RT multifunction controller is a modern all-in-one modular device with high connectivity. This CPU combines PLC tasks based on IEC 61131-3 Straton softLPLC platform with a web server, datalogger, remote control, teleservice, and energy management functionalities (according to IEC 60870-101/104, IEC 61850 protocols). The controller can be used with different architectures and configurations depending on the complexity of the system and the hardware requirements.

Z-TWS4-RT is an advanced control system with 4 built-in I/O's, 1 CAN port, 3 serial ports, 1 USB port, and a dual Ethernet port. This CPU is designed for plant automation (Straton - Soft PLC IEC 61131-3) and Energy Management applications (thanks to IEC 60870-5-101, IEC 60870-5-104, IEC 61850 protocols). Z-TWS4-RT is also a Linux-based CPU conceived for data acquisition and control applications.
