The query "Parameter lesen" (read parameters) takes a few milliseconds since this process triggers
the internal call "Parameter vom Modul neu einlesen" (read in parameters from module again).
The most recently read-out data is transferred.
Thus, execute the query "Parameter lesen" (read parameters) twice in 1 s intervals to read out
the current parameter data from the module.
If you only execute the query "Parameter lesen" once, in the worst case, the parameters that were
read in the last time the device was restarted will be returned.

The parameters and configuration data are not saved locally by the bus coupler. They must
be sent from the PLC to the bus coupler and the installed modules on startup.
