Meaning
The I/O module process data is
*)
- supplied to the I/O module
- ignored by the coupler
The diagnostics information of the I/O module
is
- mapped into the input process image
*)
- not mapped into the input process image
The diagnostics information of the correspond-
ing channel is
- transmitted to PROFIBUS DP master
*)
- not transmitted to PROFIBUS DP master
If, in the case of a PROFIBUS DP fault, the
switching of substitute values is enabled by the
coupler parameterization, this data is transmitted
to the periphery in the case of a fault.
