13.3. Enabling local controls
Application
●
Protection against unauthorised operation via local controls
●
Protection against unauthorised parameter setting via local controls
Properties
Operation modes LOCAL and/or OFF can be enabled or disabled.
Condition
Actuators with parallel interface: For the function <Enable local controls>, a digital
input for the Enable Local signal has to be available and configured.
Enable/disable local controls via fieldbus commands
Actuators with fieldbus or communication interface: For control via fieldbus
interface, the command for enabling the local controls is done via fieldbus command
Fieldb. enable LOCAL.
Switching behaviour:
●
Fieldb. enable LOCAL = 1 = enable:
Operation via local controls enabled.
●
Fieldb. enable LOCAL = 0 = disabled:
Operation via local controls disabled.
Information
Actuators with fieldbus or communication interface: In the event of loss of
fieldbus communication, the local controls will be disabled since no enable signal is
present.
If the operation commands are not transmitted via fieldbus commands but via
<Additional inputs> or an additional <Parallel interface>, a digital input has to be
available and configured for disabling or enabling.
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
Information
The logic for the digital inputs may be inverted. Depending on the parameter setting
(e.g.Coding DIN 5M0127), the input is either High active or Low active. Default setting
is High active.
