Fieldbus coupler 750-333

3.1.1Description

The fieldbus coupler 750-333 displays the peripheral data of all I/O modules in the WAGO-I/O-SYSTEM 750 on PROFIBUS DP.

In the initialisation phase the bus coupler determines the physical structure of the node and creates a process image from this with all inputs and outputs. I/O modules with a bit width smaller than 8 can be combined to form one byte in order to optimise the address space.

In addition the possibility exists to deactivate projected I/O modules. In this manner the physical structure of the node can be individually designed with regard to the peripheral signals, without undertaking any changes to an already existing control application.

The diagnosis concept is based on an identification and channel based diagnosis in accordance with EN 50170. Thus it is not necessary to program modules for the evaluation of manufacturer specific diagnosis information.

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

•Automatic recognition of transmission speed on the PROFIBUS from

9.6kBd 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
