WAGO Corporation (www.wago.us) is now offering a new Ethernet fieldbus controller that can process 1,000 instructions in just 235 μS. Using the company’s second generation Ethernet platform, it also offers upgraded memory capacity for web applications and PLC programs, along with an embedded dual-port Ethernet switch.
“We are both upgrading the processor and offering enhanced features in our new Ethernet products,” said Charlie Norz, WAGO’s I/O System Product Manager. “Ethernet 2.0 is compatible with our existing platform and still uses a rackless design, which means the I/O modules fit together on a DIN rail and the user can easily add or subtract modules as needed.”
“We have upgraded our processor, so that it is 100 percent faster than our existing products, and a new file system on the controller enables the user to log more data or store web pages. The new controller doubles the amount of available memory, offering 1 Mbyte of program memory and a 2 Mbyte file system,” Norz added.
The keys to the fast processing capabilities of the 750-881 are the upgrade in program memory and a new 32-bit CPU. The Fast File System supervises substantial data logging and a web-based management system, while an e-mail capability is also offered for authorized personnel. The standard CoDeSys V2 programming environment for the 750-881 is IEC 61131 compatible and offers all five programming languages. Up to 250 I/O modules can be supported by the PFC that allows machine users to tailor solutions from among 400+ digital, analog and specialty modules.
The additional processing power in WAGO’s new second generation Ethernet platform also allows the programmable fieldbus controller to process 1,000 instructions in just 235 μS.
