In dialects 21 to 27 or later you can read out the temperature of the CPU (processor) chip itself. We deleted this in dialect 28 to recover memory space for more useful functions.

An SPxPoll4 0,!CPU returns the floating point temperature of the CPU chip in °C at locations U(0) –> U(3)

An SPxPoll4 1,!CPU returns the floating point temperature of the CPU chip in °F at locations U(0) –> U(3)

Once you have the temperature in U(0)-U(3) you can transfer it to W using UtoW 0
