Auto change-over I/O (during fieldbus failure)

Requirements
Properties
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 parallel interface signals only.
Irrespective of the signal assignment of the inputs of the parallel interface, the
fieldbus communication with the DCS will remain intact.
Change-over to passive channel
Required user level: Specialist (4) or higher.

Application functions M0178
Activation M0212
Fieldbus operation M1236
Default value: Commands&feedback
Setting values:
Operation commands can be executed both via fieldbus and the inputs of the parallel
interface (I/O interface).
Operation commands are exclusively permitted via parallel interface (I/O) interface.
Fieldbus is only used for feedback signals.
The function is only available for a combination of additional bus inputs or parallel
interface (I/O) and a fieldbus interface.
If this function is activated, automatic change-over to the parallel interface (I/O) will
be performed on loss of fieldbus communication.
Change-over is performed before activation of <Failure behaviour> or <EMERGENCY
behaviour>.
