Re: can bus receive and transmit

I don't see any problem with math here. You can use MAP functional block for it: https://cannylogic.com/docs/fbd/converters/map/

If you need to send to and receive from same CAN bus, then CANNY 7 looks suitable for it.

But if you need to alter the CAN messages using "man-in-a-middle" technique, then you need CANNY 7.2 Duo
