Interbus S buscoupler with extended diagnostics 750-304/000-001
The Interbus S buscoupler with no. 750-304/000-001 has the possibility of extented diagnostic functions. The technical data is the same as 750-304.
Different from the standard buscoupler, a word for diagnostic messages is put into the input data process image and a word for the control of the diagnostic input is put into the output data process image.
The maximum number of input and output modules is reduced by the additional diagnostic function because Interbus S transmits only 31 words of a process image.
Order of the diagnostic status word: |

Channel: This is the location for the fault input of a module. The counting is done in the same way as numbering channels.
Module: This is the number of the module. Counting starts at the fieldbus coupler. The first module attached to the coupler is module 0.
The diagnostic control word is for diagnostic actions. E.g. error messages can be cleared in this way.
