750/753 Series I/O-System Fieldbus Coupler PROFIBUS DP; 2nd Generation; 12 MBd

Item no. 750-333
Fieldbus Coupler PROFIBUS DP; 2nd Generation; 12 MBd


This buscoupler interfaces the I/O modules of the WAGO‐I/O‐SYSTEM to PROFIBUS DP.

When initializing, the buscoupler determines the module structure of the node, to create the process image in PROFIBUS. In order to optimize addresses, the I/O modules with a bit width smaller than 8 are grouped in one byte.

It is furthermore possible to deactive I/O modules and to modify the image of the node according to the connected signals without having to modify the existing application.

The diagnosis concept is based on diagnostics according to the EN 50170 standard. Therefore the programming of modules is not necessary to interpret the diagnostic information from each manufacturer.
