Register 41041 is the state of the PO1relay.
REG(41041) = 0: open relay
REG(41041) = 1: close relay
“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” uses 1 register to encode a 16bit integer or a bit field.
Example (bits):
Register 41101 contains the device status indicators.
REG(41101) = b0000000000000101 REG(41101)(bit00) = 1: the
device is running
REG(41101)(bit01) = 0: the timer is not running
REG(41101)(bit02) = 1: regulation and alarms of a least one meas‐
urement channel is being started
REG(41101)(bit03) = 0: there is no active timer
REG(41101)(bit04) - (bit15) = 0: not used
“dword” uses 2 registers and allow to code a 32-bit integer or bit
field.
Example:
Register 41092 contains the local time of the device, this time cor‐
responds to the number of seconds since January 1, 1970.
April 27, 2015 at 3h35min19sec corresponds to 1430141719 sec‐
onds since the reference date, the hexadecimal value is
0x553E3B17.
REG(41092) = 0x3B17
REG(41092) = 0x553E
“dword” uses 2 registers and allow to code a 32-bit integer or bit
field.
Bit 00 = 1 : Parameter ON (Regulation and alarms)
Bit 01 = 1 : Associated sensor(s) in start-up phase (Active delay)
Bit 02 = 1 : Parameter paused
Bit 03 = 0 : Circulation contact or active flow meter (Ex : No water
circulation in the room)
Bit 04 = 1 : Associated sensor(s) requiring maintenance (‘Key’ logo
displayed)
Bit 05 = 1 : Parameter during dosing
