(1) Modbus register number 1 is equivalent to Modbus address 0x0000.
(2) Registers 609 to 622 must be read as one block, all at one single request.
(3) Registers 945 to 954 must be read as one block, all at one single request.
(4) For registers 609 to 622 when counter reaches its maximum value (65 535), the next incremental max value will
cause the counter to wrap to zero.
(5) For registers 513 to 576 (Analog Sensor OK Max/Min) presented value is in mV except when measurement type
is configured as Temperature. For Temperature measurement, sensor OK limit is either in °C or °F presented
with one decimal. (Value is 10 times bigger than real value since last digit is the decimal value.)
(6) Each relay status register (129-136) contains in the lowest 4-bits the status of the 4 relays controlled by that
RLM slave. Bit set means the relay is active (in its alarm state). It does not directly indicate the state of the relay
(energized or not). Bits 4-15 are not used.
Example:
Register 130 returns 0x0001
Relay 5 is activated, relays 6-8 are not.
MSB = Most Significant Bits
LSB = Least Significant Bits
