Parameter Descriptions
6-53 Terminal 42 Output Bus Control
Range: Function:
0 % [0 - 100 %] Holds the level of output 42 if controlled by
*
bus.
6-54 Terminal 42 Output Timeout Preset
Range: Function:
0 % [0 - Holds the preset level of output 42.
*
100 %] If a timeout function is selected in
parameter 6-50 Terminal 42 Output, the output
is preset to this level if a fieldbus timeout
occurs.

3.7.7 6-6* Analog Output 2 MCB 101
Analog outputs are current outputs: 0/4–20 mA. Common
terminal (terminal X30/8) is the same terminal and
electrical potential for analog common connection.
Resolution on analog output is 12 bit.
6-60 Terminal X30/8 Output
Option: Function:
Select the function of terminal X30/8 as an
analog current output. Depending on the
selection, the output is either a 0–20 mA or
4–20 mA output. The current value can be
read out in the LCP in
parameter 16-65 Analog Output 42 [mA].
[0] No When no signal on the analog output is
operation present.
