Non-connected channels
So that non-connected output channels of the AO 8 x 12 Bit are de-energized, you must set the
"Output type" parameter as "disabled". Disabled channels can remain unconnected.
Connection of loads and actuators
You must connect loads to CHx + and the reference point of the analog circuit CHx – of a current
output.
Redundant use
In redundant mode, the AO8x12Bit modules are present in duplicate and are configured and
operated redundantly.
