{ 1 }
0 =
Only in RAM
, changes to the parameter settings are no longer saved on the EEPROM.
All previously saved settings are retained, even if the FI is disconnected from the mains.
1 =
RAM and EEPROM
, all parameter changes are automatically written to the EEPROM
and remain stored there even if the FI is disconnected from the mains supply.
2 =
OFF
, no saving in RAM and EEPROM possible (no parameter changes are accepted)
NOTE:
If BUS communication is used to implement parameter changes, it must be ensured
that the maximum number of write cycles (100,000 x) in the EEPROM is not
exceeded.

PLC:
A stored PLC program is also protected by the settings "
0"
or "
2"
. However,
with the setting "
0"
the PLC program can also not be loaded or executed.

For devices which communicate via an AS interface (only possible for SK 270E-FDS and
SK 280E-FDS) this is performed by the setting of the communication protocol.
After the mode has been set, the display reverts to the value 0.
The factory setting of the AS-i mode is made according to the version of the device and can be
checked in P746.
0 =
No change
1 =
4IO+CTT2=7.A.7+7.A.5:
Double slave
(A/B-Slave + CTT2-Slave) in the extended
address range, with extended data transfer for cyclical exchange of process data
2 =
4IO+4IO=7.A.7+7.A.7:
Double slave
(2 x A/B-Slave) – in the extended address range
3 =
Reserved
16 =
4IOStd=7.F:
Single slave
– in the standard address range
17 =
Reserved
32 =
4IOExt=7.A.7:
Single slave
(A/B slave)- in the extended address range
33 =
Reserved
NOTE:
Switching can only be performed between AS-i modes which match the hardware
configuration of the device. E.g. switching between a single slave and a double
slave configuration is not possible. Such an attempt is suppressed by the
frequency inverter and generates an error message.
NB:
Avoid changing the AS-i mode more than 10 times.
Frequent
changes damage the device Changes are then no longer possible.
This parameter is only function above AS-i – Version 1.3 (see parameter P745).
