OM
Control of the logic outputs by the host application
The logic outputs can be controlled by the host application (as opposed to the normal internal setpoints) if
they are enabled by the IM command and the appropriate 4 digit code.

Enable Output 3
A “1” bit in the code enables the corresponding logic output to be controlled by the host application using
the IO command. A “0” in the code leaves the corresponding logic output controlled by the internal setpoint.
Logic output 1 is again the least significant bit.

Note:
When reading the status of the logic outputs using the IO command, the setpoint status will be
returned regardless of the OM setting. Sending OM_0000 disables the external logic output control.
Factory default: OM=0 000
AI
Function of Logic Input 1, 2 or 3
The DAS 72.1 has 3 independent logic inputs. These inputs can be configured as follows:

AI_1
¿
I1:+00000
no function
AI_1_6

Similarly to read or set the logic input 2 or 3, use AI_2 or AI_3 instead of AI_1.
Factory default: 0
