The programmable fieldbus controller for ETHERNET combines the functionality of the ETHERNET fieldbus coupler with the functionality of a Programmable Logic Control (PLC). Programming of the application is done with WAGO-I/O-PRO 32 in accordance with IEC 61131-3. Via the API socket the user can program all clients and servers for the transport protocols (TCP, UDP,...) using function modules. Characteristics and use:
l The use of decentralized control can better support a PLC or PC
l Signal pre-processing reduces fieldbus transmissions
l Complex applications can be divided into multiple tasks
l Tasks can be prioritized
l Peripheral equipment can be controlled directly, resulting in faster system response times
l Programmable response in the event of a fieldbus failure
l Simple, self-sufficient control
