Controller ETHERNET; 3rd Generation; Media Redundancy
In conjunction with the WAGO-I/O-SYSTEM, the ETHERNET Controller serves ETHERNET networks requiring fast and safe media redundancy. The controller supports all digital, analog and specialty modules found within the 750/753 Series, and is suitable for data rates of 10/100 Mbit/s.
Media redundancy is achieved by operating the controller in two separate networks – which is accessible via two different IP addresses (including two MAC IDs). Cross communication between separate channels is not possible. The two separate ETHERNET interfaces allow redundant connection of two transmission paths (no hub or switch required). Both interfaces support Auto-Negotiation and Auto-MDI(X). The DIP switch configures the last byte of both default IP addresses and may be used for IP address assignment (DHCP, BootP).
The media redundancy controller is designed for fieldbus communication via MODBUS in ETHERNET networks. It also supports a wide variety of standard ETHERNET protocols (e.g., HTTP, BootP, DHCP, DNS, FTP). An integrated Webserver provides user configuration options, while displaying PLC status information.
The IEC 61131-3 programmable controller is multitasking-capable and features a battery-backed RTC.
