Device Description
The 750-333 fieldbus coupler maps the peripheral data of all available I/O
modules of the WAGO I/O SYSTEM 750 on PROFIBUS DP.
In the initialization phase, the fieldbus coupler determines the physical structure
of the node and creates a local process image with all inputs and outputs from
the data that is obtained. In order to optimize addresses, the I/O modules with a
bit width smaller than 8 can be grouped in one byte.
The physical structure of the fieldbus node may be individually adapted to the
configuration of each system without changing the I/O addressing of a global
control application of the higher-order controller. This is done by appropriate
parameterization of the configuration modules within the DP Master
configuration.
The diagnostics concept is based on the identifier and channel-related
diagnostics, as well as the module status and DP/V1 status messages according
to EN 50170.
Thus, there is no need for programming I/O modules for evaluating manufacturer-
specific diagnostic data.
