3.1.4.3 Process Images of the I/O-Modules with PROFIBUS-DP

The input and output data of the digital modules are mapped to the Profibus bit

by bit. The configuration of the node determines whether each module

occupies a byte or the data of several modules is grouped in one byte.

The input and output data of the analog modules (D0...Dn) are mapped via

bytes.

In addition to data bytes, specialty modules (counter modules, pulse width

output module, etc.) also send Status Bytes (S) to the Master or receive

Control Bytes (C) from the Master.

Depending on the configuration of the coupler, the status, control and data

bytes of the byte-oriented modules are sent in the Motorola or in the Intel

format.

Note

For the number of input and output bits or bytes of the individual I/O

modules please refer to the corresponding I/O module description.
