PROFIBUS DP Slave Module
Reference
The following lines in the [Backplane] section of the configuration file define the
starting registers for Input and Output data. 122 words of data will be transferred
between the module and the processor during every scan.
Input Start Register
Output Start Register
: 1 #3x word offset where data is placed by module
: 1 #4x word offset where data is read by module
Use the PROFIBUS configuration tool to set the number of words to be
transferred on the PROFIBUS master.
The appearance of the View Inputs and View Outputs screens on the
Configuration/Debug menu depend on the configured size of the Input and
Output registers.
For example, if the PROFIBUS configuration tool configured 100 words for both
inputs and outputs, the PROFIBUS Slave inputs and outputs screens would
resemble the following illustrations:

If the PROFIBUS configuration tool configured 32 words for both inputs and 24
for outputs, the PROFIBUS Slave inputs and outputs screens would resemble
