Can messages

[elecLear78]

I have several clarifications with respect to can messages.
1. There are CAN messages with raw and physical values. What exactly is the difference. I keep getting confused with these terms.
2. In can messages they have a multiplication factor and offset. Why exactly they're there? In my program once I receive these messages can I process them as it is or should I multiply them or divide them and while sending out should I again multiply them?
3. And most important what is intel format and Motorola format in this messages?
Please help.

There is nothing like that in the CAN specification. There is a single data frame which transfers 8 bits of data. See https://en.wikipedia.org/wiki/CAN_bus#Data_frame
Raw and physical values and motorola vs intel are properties of the data protocol that uses CAN as a transfer medium. You need to specify what that protocol is if you want to get any answers.

"CAN" works better if you keep the string tight.
