Electronics controller I/O interface PLC Wago

WAGO Compact Controller 100 remains a small-scale PLC with a wide variety of built-in I/O for use in smaller applications.  While the PLC can still interface with industrial devices using protocols such as MODBUS TCP/UDP, EtherNet/IP or EtherCAT using the two on board EtherNet ports; device now includes communication protocols such as BACnet, OPC/UA and DNP3 for the utility sector. By programming the product using Codesys 3.5, it allows users to code in one or more of the IEC 61131-3 compatible languages as well as utilize the controller’s built-in Web Server to develop HTML 5 visualizations. The two flexible Ethernet ports allow for use of a switch or two unique IP addresses, with one port for field devices and the other for SCADA or Cloud services. The wide variety of built-in digital and analog I/O plus RTD inputs can be used with WAGO’s 750-362 MODBUS Coupler for I/O expansion in any application.
