Buffer mode selection (XX = 00...02)
Poll of the buffer data (only one current packet!)
Buffer mode 00: answer: AAAA
AAAA = Measured temperature (0xF001 => Overflow)
Buffer mode 01: answer: AAAABBBBCCCC
AAAA = Measured temperature (0xF001 => Overflow)
BBBB = ffff
CCCC = ffff
Buffer mode 02: answer: AAAABBBBCCCCDDDDEEEEFFFFGGHHIIJJ
AAAA = Measured temperature (0xF001 => Overflow)
BBBB = ffff
CCCC = ffff
DDDD = Setpoint value at ramp function (current ramp setpoint value!)
EEEE = (Analog) control output (0-1000) in % (0.0-100.0%)
FFFF = ffff
GG = Data status byte 0
HH = Data status byte 1
II = Data status byte 2
