9.2.12 PID Registers
Registers 37, 38, 39, 41 and 45 are associated with the PID function and are sent over the modbus communication
network in signed internal units.
Example: An Actual PID setpoint value of 999.0 would be transmitted as 9990 (27 06 hex) where an actual PID
setpoint value of -999.0 would be transmitted as -9990 (D8 FA hex).
