2.3.4 Configuration by Controller Application
The second option to configure the Slave module is to let the controller
application decide on the configuration. To do so the parameter "Force User
Config" in the configuration array has to be set to 1. By setting this parameter
and initialization of the other values the controller program can configure the
slave. With this method the slave module will not start any network
communication as long as the master and slave configuration don't match to
each other. The following table shows the outline of the mapping of the
configuration data image.
