Fieldbus Controller 750-806
3.2.1 Description
The programmable fieldbus Controller 750-806 (short: PFC) combines the DeviceNet functions of the fieldbus Coupler 750-306 with that of a programmable logic control (PLC).
The application program is created with WAGO-I/O-PRO 32 in accordance with IEC 61131-3.
All input signals of the sensors are grouped in the Controller.
According to the IEC 61131-3 programming, data processing occurs locally in the PFC. The link results created in this manner can be put out directly to the actuators or transmitted to the higher ranking control system via the bus.
The programmer has access to all fieldbus and I/O data.
In the initialization phase, the fieldbus Controller determines the physical structure of the node and creates a process image from this with all inputs and outputs. This could involve a mixed arrangement of analog (word by word data exchange) and digital (byte by byte data exchange) modules.
The local process image is subdivided into an input and output data area.
The data of the analog modules are mapped into the PDOs according to the order of their position downstream of the bus Coupler. The bits of the digital modules are compiled to form bytes and also mapped into PDOs. Should the number of digital I/Os exceed 8 bits, the Coupler automatically starts another byte.
In addition to the functions of the fieldbus Coupler, the fieldbus Controller supports the following DeviceNet functions:
•Create Connection via UCMM-Port
•Offline Connection Set
•DeviceNet Shutdown
•Dynamic assembly
•Change MAC ID by SW
•Heartbeat
•Bit-Strobe
