The programmable fieldbus coupler 750-833 combines the PROFIBUS DP-
functions of the fieldbus coupler 750-333 with that of a programmable logic
control (PLC). The application program is created with WAGO-I/O-PRO in
accordance with IEC 61131-3. The programmer has access to all fieldbus and
I/O data.

•  Load relief for the central controls using decentral processing units

•  Dividing complex applications into individual testable units

•  Programmable fault reaction in the case of a fieldbus system failure

•  Load relief of the communication system PROFIBUS DP by signal proc-

essing

•  Reduction of reaction times by direct access to the periphery (without hav-

ing pass through the fieldbus system PROFIBUS DP)

•  Autarcic smallest scale controls  (station address 0)

•  Use for decentral and central control

•  Programmable in accordance with IEC 61131-3 in all 5 languages: IL, LD,

FBD, ST and SFC

In the initialisation phase the bus coupler determines the physical structure of
the node and creates the process image of all inputs and outputs on this basis.
I/O modules with a bit width of less than 8 can only be grouped to one byte in
each case in order to optimise the address space.

It is also still possible to deactivate projected I/O modules. In this manner the
physical structure of the node can be individually structured with reference to
its periphery signals, without touching an already existing control application.

The diagnosis concept is based on the identification and channel based diagno-
sis in accordance with EN 50170. In this manner it is not necessary to program
modules for evaluation of the manufacturer specific diagnosis information.

•  Max. process data length 128 Byte (input  and output process image)

•  Automatic recognition of the transmission speed on the PROFIBUS of

9.6 kBd to 12 MBd

•  All I/O modules from the WAGO-I/O-SYSTEM 750 are supported

•  Configuration modules can be parameterised as wildcards.

•  Parameterable substitute value for each channel

•  D-Sub 9 pole bus connection
