Odometer with PV450

Post by taylorsscott » Thu Sep 22, 2011 7:32 am

I have a customer requirement for a odometer yet I do not have SPN 1032 Total ECU Distance nor SPN 245 Total Vehicle Distance available. Has anyone came across this and created a way to calculate total distance based off other CAN parameters to display on a PV450?

Hello taylorscott,

Here is a configuration that calculates Total Vehicle Distance from "J1939.Engine.Wheel Based Vehicle Speed".

The variable "UserDefinedVariable.Distance.Total" holds the value.

It is calculated by executing this calculation event every second:

Code: Select all

"UserDefinedVariable.Distance.Total" + ( ( "J1939.Engine.Wheel Based Vehicle Speed" / 60 ) / 60 )
The variable is saved to non-volatile memory ever 60 seconds.

"J1939.Engine.Wheel Based Vehicle Speed" has an event in fire on change that causes the transition to the loop that executes the calculation event every second. This is to make sure that "J1939.Engine.Wheel Based Vehicle Speed" is valid because if it is invalid, the result of the calculation event will also be invalid.

Regards,

I am trying to implement the code you provided into my Configuration, but I am running into errors on state "Initialize Distance and Speed" and also "Calculate Distance and Speed."

Can you please help resolve these errors?

Regards

I think the problem was a partial download:
viewtopic.php?f=7&t=117

When I downloaded the file it was smaller than the 3.02 MB so tried again and the second time it downloaded the full file and I was able to create the configuration without errors.
