Switching behaviour:
●
Fieldb. enable LOCAL
= 1 = enable:
Operation via local controls enabled
●
Fieldb. enable LOCAL
= 0 = Priority REMOTE:
Operation via local controls disabled
If the operation commands are not transmitted via fieldbus commands, but via
<Additional inputs> or additional <Parallel interface>, a digital input has to be available
and configured for the <Priority REMOTE> function.
Configuration of digital input
Required user level:
Specialist (4)
.
Device configuration M0053
I/O interface M0139
Digital inputs M0116
Example
Use input DIN 5 for signal
Enable Local
:
Parameters:
Signal DIN 5
M0122
Setting value:
Enable Local
(wiring diagram designation:
Enable LOCAL
)
Information
The logic for the digital inputs may be inverted. Depending on the parameter setting
(e.g.
Coding DIN 5 M0127
), the input is either
High active
or
Low active
. Default
setting is
High active
.
Priority REMOTE via digital input
Switching behaviour for coding
High active
:
●
Input
Enable Local
= high level (standard: +24 V DC):
Operation via local controls enabled
●
Input
Enable Local
= low level (0 V DC or input open):
Priority REMOTE: Operation via local controls disabled

Priority REMOTE behaviour
This function determines which selector switch function (LOCAL, OFF) requires an
additional enable signal.
Required user level:
Specialist (4)
or higher.
Customer settings M0041
Local controls M0075
Priority REMOTE M0773
Default value:
Sel. sw. Local
Setting values:
Sel. sw. Local
Priority of control from REMOTE is only effective in operation mode LOCAL (selector
switch is in position Local control). If no enable signal is present, operation via push
buttons on the local controls is disabled and the actuator can be controlled from
