2.1 System Description
2.1.1General
The WAGO-I/O-SYSTEM 750 consists of various components which are capable of providing modular and application specific fieldbus nodes for various fieldbusses.
A fieldbus node (short: Node) consists in principle of a fieldbus coupler (short: Coupler) ) or Programmable Fieldbus Controller (short: Controller) ) (1) at the front end, a number of special I/O modules (2) and a End Module (3) which is placed at the other end.

6• WAGO-I/O-SYSTEM 750
System Description
2.1.2Coupler/Controller (1)
The Coupler/Controller forms the link between the fieldbus and the field devices with their I/O functions. All control functions required for the faultless operation of the I/O functions are carried out by the Coupler/Controller. The connection to different fieldbus systems is established by each of the corresponding Coupler/Controller, e.g. for PROFIBUS, INTERBUS, CAN, MODBUS etc. In this way a change of the fieldbus system is possible.
The programmable fieldbus controller 750-833 combines the PROFIBUS DP functionality of the fieldbus coupler 750-333 with the functionality of a Programmable Logic Control (PLC). Programming of the application is done with WAGO-I/O-PRO in accordance with IEC 61131-3, covering all 5 programming languages. The programmer can access all fieldbus and I/O data.
Characteristics and use of the Controllers:
•The use of decentralized control can better support a PLC or PC
•Signal pre-processing reduces fieldbus transmissions
•Complex applications can be divided into multiple tasks
•Tasks can be prioritized
•Peripheral equipment can be controlled directly, resulting in faster system response times
•Programmable response in the event of a fieldbus failure
•Simple, self-sufficient control
