| STEEL IP65 ENCLOSURES 10/100 Mbit/s CARRIER RAIL DIN 35 CAGE CLAMP CONNECTION |
| This buscoupler allows connection of the WAGO-I/O-SYSTEM as a slave to the ETHERNET fieldbus. The buscoupler is capable of supporting all the I/O modules. The buscoupler automatically configures, creating a local process image which may include analog, digital or specialty modules. Analog and specialty module data is sent via words and/ or bytes, digital data is sent bit by bit. This buscoupler is suitable for data rates of 10 Mbit /s and 100 Mbit /s. It is programmable according to IEC 61131-3 using 512 KB program memory, 128 KB data memory and 24 KB retentive memory. This 32-bit based CPU is capable of multitasking and has a battery-backed real-time clock. The controller offers many different application protocols which can be used for data acquisition or control (MODBUS, ETHERNET / IP) or for system managing and diagnostics (HTTP, BootP, DHCP, DNS, SNTP, FTP and SNMP). HTML pages can be placed on an internal server for use in Web-based applications. Programs can be directly accessed via XML and ASP. Library functions for mail, SOAP, ASP, IP configurations, ETHERNET sockets and filesystem complement the product profile. |
