Device Description
The Fieldbus Controller DeviceNet
TM
750-806 links the
WAGO-I/O-SYSTEM 750 to the DeviceNet
TM
fieldbus system.
This fieldbus controller can be used for applications in mechanical and systems
engineering, as well as in the processing industry.
The fieldbus connection is made via series 231 5-pin plug connector
MULTI CONNECTION SYSTEM (MCS)
.
The DIP switch can be used to specify baud rate and station address of the
fieldbus controller.
WAGO-I/O-
PRO
creates application programs that adhere to IEC 61131-3.
CODESYS by 3S (the standard programming system) serves as the basis of
WAGO-I/O-
PRO
, which was expanded specifically with the target files for all
WAGO controllers.
Compatibility with IEC-61131-3 programming software!
The compatibility between your fieldbus controller and the IEC 61131-3
programming software used depends on the fieldbus controller's firmware
version and the version of the programming software.

Use the search function (search for “Compatibility Notes”).
According to IEC 61131-3 programming, data processing occurs in the PFC. The
process results can be output directly on sensors/actuators or transmitted via
fieldbus to the higher-order controller.
The fieldbus controller has 128 KB program memory, 64 KB data memory and
8 KB retentive memory available for the IEC 61131-3 programming.
In the fieldbus controller, all input signals from the sensors are combined. After
connecting the fieldbus controller, the fieldbus controller determines which I/O
modules are on the node and creates a local process image from these. Analog and
specialty module data is sent via words and/or bytes; digital data is grouped bit-
by-bit.
The data of the analog modules is mapped first into the process image. The
modules are mapped in the order of their physical position after the controller.
The bits of the digital modules are combined into bytes and then mapped after the
analog ones in the process image. If the number of digital I/Os is greater than 8
bits, the Fieldbus Controller automatically begins a new byte.
Depending on configuration the user can access all fieldbus and I/O data.
