Press Release Summary:
Ethernet-based Model 750-841 is protected against unauthorized access by means of built-in IP filter. Communication parameters are established via list of trust worthy devices, and, based on IP address and port number transmitted by device, controller can identify whether or not to send or receive information from that unit. Model 750-841 includes multi-tasking 32-bit CPU with real-time clock, 512 KB program memory, 128 KB data memory, and 24 KB retentive memory.
Original Press Release:
Ethernet Based PLC with IP Filter
Germantown, WI, June 2005 - WAGO Corporation is pleased to announce the 750-841 Ethernet based programmable controller is now protected against unauthorized access by means of a built-in IP-filter.
"This added functionality allows controlled access to both control and configuration data," claims Mark DeCramer, Advanced Electronics Product Manager for WAGO Corporation. "Thereby, adding another level of security to the Ethernet."
Configuration of the IP-filter is facilitated by means of web pages in the controller. When the security option is switched on, only certain nodes can communicate with the 750-841. These communication parameters are established via a list, of trust worthy devices, stored directly in the controller. Based on the IP address and port number transmitted by the device, the controller can identify whether or not to send or receive information from that device.
The 750-841 Ethernet based controller boasts a powerful multi-tasking 32 bit CPU with a real-time clock, 512 KB of program memory, 128 KB of data memory, and 24 KB of retentive memory. In addition to supporting MODBUS/TCP, MODBUS/UDP, and EtherNet/IP network protocols, the controller also supports a number of Ethernet protocols for system management and diagnostics such as HTTP, BootP, DHCP, DNS, SNTP, FTP, SOAP, SNMP and SMTP.
