MODBUS FUNCTION USE
01 Discrete Coil Status
02 Discrete Input Status
03 Holding Register
OWDMANUAL 1114
Reads output coil status,
digital outputs
Reads state of individual
digital inputs
Reads and writes to
the DAC channels (0-3).
Takes a converted float
value (from 2 unsigned
int values) and updates
the DAC output values
(in Volts 0-10VDC).
