(1) : It isn’t possible to set a High alarm lower than a Low alarm and vice versa.
(2) : To disable a low or high alarm you must send a NaN.
2) Data formatting
BOOL
“bool” uses 1 register and can have two values 0 or 1.
Example:
Register 41041 is the state of the PO1relay.
REG(41041) = 0: open relay
REG(41041) = 1: close relay
REAL
“real” uses 2 registers and allows coding of floating point values on 32bits.
Example :
Register 41303 is the measurement value of channel E03, the unit of this value is the unit
selected in the measurement menu of the device.
For a measurement value of 1.94ppm, the hexadecimal encoding is 0x3FF851EC.
REG(41303) = 0x51EC
REG(41303) = 0x3FF8
WORD
“word” uses 1 register to encode a 16bit integer or a bit field.
Example (bits):
Register 41101 contains the device status indicators.
REG(41101) = b0000000000000101
