10.3.5.9 Store actual parameters (STORE_PI)
With this call, the configured parameters stored on the EEPROM are overwritten
with the current, permanently stored (actual) parameters; in other words, the cur-
rent parameters of all AS-i slaves are stored.
10.3.5.10 Write parameter (WRITE_P)
The AS-i slave parameter value transferred with the command is passed on to the
addressed AS-i slave.
The parameter is stored in the AS-i/PROFIBUS Gateway only temporarily and is
not stored as a configured parameter in the EEPROM!
The AS-i slave transfers its current parameter value in the response (parameter
echo). This can deviate from the value that has just been written according to the
AS-i master specification.
