Signal handling for information to be shown on display

Jay Raut 4 years ago in IQANdesign • updated by Gustav Widén (System support) 4 years ago • 1

I want to display some information on an MD4 display, which is coming from the Engine ECM via CAN bus.

The Engine ECM is connected on CAN bus D. where as the MD4 is connected on CAN bus B.


IQAN provides me an option to directly link the data coming from the engine to each of the attributes on the display. 

For example: I am able to link the information received from Engine ECM on CAN bus D directly with the Engine RPM gauge on  MD4 display. Is this approach correct?

OR 

Another way I could think of is to relay the information received from CAN bus D to CAN bus B with the help of a proprietary CAN message.  and then link that signal to the display.

Can you guys please help?

You can connect channel values from any IQAN master module in the system to the MD4 display pages of that same project file. 

Just read the J1939 signals using JFIN and JPIN channels, then you can access it on all MD4 display pages.
