14.5.4 Multiplexer/Demultiplexer
The multiplexer/demultiplexer enables the transfer of various digital signals between
an overriding controller and frequency inverters via field bus or between frequency
inverters via the system bus. For parameterization of the multiplexer and demultip-
lexer using the VTable application, the commissioning and diagnosis software VPlus,
version 4.0.2 or higher is required.
Multiplexer:
The multiplexer features 16 inputs for logic signals or digital input signals.
On the output, the logic signal 927 - Output MUX for the inputs of the TxPDO process
data of the system bus or for PZDx-IN process data of the Profibus can be used.

1252 Mux inputs 7 - Off
The parameters
Mux input index (write)
1250 and
Mux input index (read)
1251 for
the input signals of the multiplexer enable parameterization via the control unit
KP500 or the application VTable in VPlus.

Non-volatile (fixed parameterization): Volatile:
0: All indices in EEPROM 17 All indices in RAM
1…16: One Index of 1…16 in EEPROM 18…33: One Index of 1…16 in RAM
Note:
The setting "0" for
Mux input index (write)
1250 changes all data in
EEPROM and RAM.
In the case of non-volatile storage (0…16), the changed values are still available
when power supply is switched on again.
In the case of volatile storage (17…33), the data is only stored in RAM. If the unit is
switched off, this data is lost and the data required are loaded from EEPROM after
restart.
Demultiplexer:
The demultiplexer features an input
DeMux Input
1253 whose signal can be for the
process data RxPDO of the system bus or OUT-PZDx of Profibus.
On the output of the demultiplexer, the logic signals „910 - Output DeMux Bit 0“ to
„925 - Output DeMux Bit15“ are available, e.g. for control of FT-instructions.
