Priority 3 Not Required for Receive Data

Data Length 5 Message Data

EEC1.Status_EEC1 - Name to access byte 1 of message

EEC1.Drive_DMD_Eng - Name to access byte 2 of message

EEC1.Actual_Eng - Name to access byte 3 of message

EEC1. EngRPML - Name to access byte 4 of message

EEC1. EngRPMH - Name to access byte 5 of message

EEC1. NoRSP - Name to access No Response Status bit

Code Example

Dim EngRpm as Uint ‘Define storage location for RPM Calc J1939

Dim EngTorque as Uint ‘Define storage location - Actual Engine Torque

EngRpm = (EEC1.EngRPMH * 256 + EEC1.EngRPML) / 8 ‘Convert from 0.125 RPM to 1 RPM per bit

If (EEC1.Actual_Eng > 124) then ‘Test to see if positive %Torque

‘ -note %Torque Resolution 1% pbit, -125% offset

EngTorque = EEC1.Atual_Eng – 125 ‘Engine Torque % - offset of 125% = positive %

Else

EngTorque = 0 ‘Use 0% when negative % detected

End if

Note: The Engine RPM example first converts two bytes into one number and then converts from 0.125 RPM

per bit into 1 RPM per bit.
