6 Parameterization and configuration
Parameterization
Parameterization means providing a PROFIBUS-DP slave with certain information
required for operation prior to commencing the cyclic exchange of process data. The
measuring system requires e.g. data for Resolution, Count direction etc.
Normally the configuration program provides an input mask for the PROFIBUS-DP
master with which the user can enter parameter data or select from a list. The
structure of the input mask is stored in the device master file. The number and type of
the parameter to be entered by the user depends on the choice of nominal
configuration.
The configuration described as follows contains configuration and parameter
data coded in their bit and byte positions. This information is e.g. only of
significance in troubleshooting or with bus master systems for which this
information has to be entered manually.
Modern configuration tools provide an equivalent graphic interface for this
purpose. Here the bit and byte positions are automatically managed in the
"background". The configuration example on page 124 illustrates this again.
