Ethernet 2.0 Controller Suitable for Shipbuilding
Wago has introduced an Ethernet 2.0 media redundancy controller that is suitable for applications requiring high network and system availability, such as shipbuilding. The 750-882 controller provides two redundant networks via independent Ethernet interfaces. This enables communication with a redundant network or two independent networks. Simultaneous redundancy is achieved by operating the 750-882 over two networks, which are accessible via two different IP addresses and Mac IDs.
The independent Ethernet ports permit the redundant connection of two transmission paths. If port one's path fails (owing to broken cable, for example), port two serves as an alternative. If redundancy is not required, networks are addressed separately for intra-network data exchange, for example from shop-floor machinery to a top-floor manufacturing enterprise system. The Ethernet 2.0 platform provides high-speed processing - 1,000 instructions less than 235uS - and accommodates HTTP, BootP, DHCP, DNS and FTP.
The 750-882 employs an TCP/IP stack, a multi-tasking IEC61131 runtime system and Modbus/TCP with rapid response. The controller includes a 1Mbyte program memory (program code), a 512Kbit data memory and a 32Kbit retain memory. A 2MByte Fast File System, additional libraries and redundancy modes complete the package. An on-board DIP switch streamlines IP address assignment, while the integrated web server provides web pages and remote access. The IP20-rated 750-882 platform carries UL 508 and GL certifications.
