Multi-tasking PLC
Wago's new PFC200 controller can be used as a gateway between CAN and Ethernet systems.
"The thing that makes this product unique is that it has a number of different fieldbus interfaces on it," says Norz. "It can be used as a gateway between a CAN system and an Ethernet system, for example. I/O modules can also be used for direct control from the device."
Part of the fieldbus-independent Wago-I/O-System, the PFC200 line has access to 400+ analog, digital and specialty modules. This includes compatibility with hazardous location devices without separate components, such as Zener barriers. Users can cost-effectively extend the functionality of existing hazardous location applications—particularly in petroleum processing.
"This is going to be especially attractive to oil and gas and off-shore applications because it's so small and powerful," says Norz.
To suit a very diverse application range from textile manufacturing to marine engineering, the controllers employ IEC 61131-3-compatible Codesys software. This provides users familiar with standard programming languages, such as Ladder Logic, with an easy-to-use, environment for PLC programming and process visualization. More advanced users have the freedom of writing projects in C, PHP or shell scripts. Regardless of language, all programming and libraries created will interact with Codesys applications.
Each PFC200 controller carries 13 LEDs to provide operational information, such as system fieldbus and user status, at a glance. An operation mode switch (run, stop and reset) resides on the top of each controller for additional flexibility.
To provide robustness and reliability, Wago has minimized moving hardware in the PFC200 series. The units do not rely on internal cooling fans, keeping energy requirements low. The absence of rotating storage media and batter-free buffering of the real-time clock also enhance reliability, while making the units extremely shock-resistant. Wire terminations are provided by maintenance-free Cage Clamp spring pressure technology.
To support varying applications, the PFC200 line spans from an entry-level controller (Ethernet connectivity and serial connections) to a flagship unit with Ethernet, serial, CAN and Profibus connectivity. The multi-tasking PFC200 controllers enable users to perform several tasks simultaneously.
The PFC200 line will be available to customers by the end of September.
