8.2.4.8 Get List of Projected Slaves (GET_LPS)
With this call, the following entry is read out of the AS-i/PROFIBUS gateway: The
list of projected AS-i slaves (LPS).
8.2.4.9 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.
8.2.4.10 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.
Meaning of bit B:
B = 0Single AS-i slave or A-slave
B = 1B-slave
