Hello,
Please kindly advise if the following requests are feasible on the PV780. If yes, please also advise how to set by PowerVision.
1) Regarding the J1939 Engine Speed, analog signal to output proportionally within 0-2000 RPM through Frequency Output 1 (Pin #14).
2) Digital output to ON through Pin #22 when engine RPM is up to 500 RPM.
Thank you,
tshiii

Re: Engine Speed Output Request/PV780
(I moved this topic here to Programming and Configuration.)
I believe what you have asked about is very doable with PowerVision.
1) Setting the frequency output. The J1939 Engine Speed parameter to fire a Engine Speed Update event when the RPM changes.
The Engine Speed Update event fires the action to set the Frequency Output.
The Frequency Output is using the J1939.Engine.Engine Speed variable.
2) Here is an activity diagram example of setting the digital output high if the RPM is up to 500, low otherwise. The activity diagram runs on the same Engine Speed Update event.
It should be easy to change this if you want to make the frequency output proportional or take into consideration the count per RPM or if the logic is backwards on the digital output. There could be a couple ways to understand the request, but it should be easy to change.
