We're running a PDM 32 and have quite happily used 130 of the 200 allowable operations. I appreciate with a little spring clean I could tidy the logic up a little but in general it is all required.
However the following feature would be heck of a bonus..
A feature where the input / output logic can be represented by a flow diagram. The PDM uses fairly simple logic combinations and does lend itself to such a diagram type. With ever complex PDM control stratergies being used, it is become increasingly difficult to clearly see the process.
An auto generated flow diagram would allow the other engineers to quickly understand how and why the pdm activated its outputs.
(Yet another long shot request
