Combination of fieldbus-parallel interface

The described address parameters can be read via local display, using the AUMA
CDT service software or any other (e.g. FDI based) configuration and diagnostic
system.
Actuator controls with fieldbus interface can be equipped with additional digital and
analogue inputs. Depending on the version, up to 6 digital inputs (default: 24 V DC)
and two analogue 0/4 20 mA inputs are available.
If additional inputs are available, operation commands can be sent both via fieldbus
and the additional inputs.
For manual change-over between fieldbus interface and the additional inputs, a
digital input has to be available and configured.
For automatic change-over (in the event of fieldbus failure), the <Auto change-over
I/O (fieldbus failure> function is required.
Configuration of additional inputs
Required user level: Specialist (4).
Device configuration M0053
I/O interface M0139
Digital inputs M0116
Analogue inputs M0389
Use digital inputs DIN 2 to 4 for operation commands:
Signal DIN 2 M0120 = CLOSE
Signal DIN 3 M0119 = OPEN
Signal DIN 4 M0118 = STOP
Use digital input DIN 6 for manual change-over:
Signal DIN 6 M0121 = I/O interface (wiring diagram designation:
)
face
The logic for the digital inputs may be inverted. Depending on the parameter setting
(e.g. Coding DIN 6 M0128), the input is either High active or Low active. Default
setting is High active.
Manual change-over via I/O interface input
Switching behaviour for coding High active
(Default factory setting)
Input I/O interface = low level (0 V DC or input open):
Actuator controls react to operation commands via fieldbus only.
Input I/O interface = high level (standard: +24 V DC):
Actuator controls react to additional input signals only.
Irrespective of the signal assignment of the additional inputs, the fieldbus
communication with the DCS will remain intact.
Actuator controls with fieldbus interface may be additionally equipped with a parallel
interface. Depending on the version, up to 6 digital inputs (default: 24 V DC) and up
to two analogue 0/4 20 mA inputs are available via parallel interface.
For this combined version, operation commands can be executed both via fieldbus
and the inputs of the parallel interface (I/O interface).
For manual change-over between fieldbus interface and parallel interface, a digital
input has to be available and configured.
The <Auto change-over I/O (during bus failure)> function is required for automatic
change-over (bus failure).
