No. 00: Set_Permanent_Parameter - Siemens SIMATIC ET 200SP Manual

9.4.1

No. 00: Set_Permanent_Parameter

Meaning
This command configures a parameter value for the specified AS-i slave in the AS-i master.
The value is stored in the non-volatile EEPROM of the CM AS-i Master ST. The parameter
value is additionally forwarded to the addressed AS-i slave.
However, the "parameter echo" of the AS-i slave cannot be read out with this command (see
No. 02: Write_Parameter (Page 109) command).
Note
Use of other Siemens AS-i masters
Other Siemens AS-i masters do not transfer the configured parameters to the AS-i slave
immediately.
For AS-i slaves that meet the AS-i standard slave profile 7.4, this command is not permitted.
For these slaves, the AS-i master itself administers the parameter assignment of the AS-i
slave. In this case, the configured parameters are always equal to F
Note
Configuration data are overwritten
If you configure the AS-i slaves using HW Config, there is normally no need to use the
command described here.
If you use this command, you will overwrite the respective configuration data that resulted
from SET button configuration or HW Config configuration.
When this command is executed, the AS-i master switches to the offline phase and then
switches back to "normal operation". The AS-i master restarts.
