To
read
one or more registers you should use Modbus function code 3 – Read holding registers (4x
Range)
To
write
one or more registers you should use Modbus function code 16 – Write multiple registers
Note :
PWM readings are 32bit unsigned integer values recording microsecond values for the pulse width,
with a accuracy of ±8uS or better
Channel Maximum/Minimum registers record the peek value, i.e. the highest/lowest values seen by
the system, each subsequent live reading is tested against this value with the register value being
updated if the live reading exceeds the threshold value stored here.
Writing a value to the Max/Min registers will set a new threshold value for testing against.
Only function codes 0x03 (FC03) and 0x10 (FC16) are accepted by the module
