Red Lion, Crimson 3, convert 16 bit Integer to 8 Bit

Hello all, I wonder if someone might have some insight on how to convert a 16 bit Integer value into an 8 bit array in Crimson 3.

Example: Integer 12345

8 bit array:

Array[0] = 48 (12345/256=48.22)
Array[1] = 57 (12345-(48*256) =57)

Thanks,

Is this your home work?

I would look into what actually makes an integer. It is really just an array of binary digits.

No this isnt my home work, its an actual application, as my name implies, I am in fluid power not a programming expert.

Never mind, I figured it out myself, its not pretty but it will work.

Glad you got something working. Sorry for my belated response.

An 8 bit integer will be limited to 256 values 0-255. If your your 16 bit value will be larger than that you won't be able to convert a 16 bit value to 8 bit unless your store in multiple registers, I'm not sure how that would ever to useful. Essentially, you would be stripping the first 8 bit values from the 16 bit register and load those into the 8 bit register.

For example you could use a limit comparator to make sure the 16 bit integer is between 0-255 then set the 8 bit register equal to the 16 bit integer. The 0's at the end should be truncated during the operation. I find this easier to do in the Plc by just setting bits 0-7 of each integer equal to each other. This method doesn't handle any kind of overflow though.

Okay thanks for the info califflash.
