Modbus communication register Page 37/40
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 measurement channel is being
started
REG(41101)(bit03) = 0: there is no active timer
REG(41101)(bit04) - (bit15) = 0: not used
DWORD
“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 corresponds to the number of
seconds since January 1, 1970.
April 27, 2015 at 3h35min19sec corresponds to 1430141719 seconds since the reference date,
the hexadecimal value is 0x553E3B17.
REG(41092) = 0x3B17
REG(41092) = 0x553E
ParamState
“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
Bit 06 = 1 : Parameter stop dosing on alarm
Bit 07 = 1 : Parameter in pause due to a timer
Bit 08 = 1 : Associated sensor(s) out of scale or disconnected
Bit 09 = 1 : Associated sensor(s) measuring low out of scale
Bit 10 = 1 : Associated sensor(s) measuring high out of scale
Bit 11 = 1 : Associated sensor(s) unstable measurement
Bit 12 = 1 : Low alarm active parameter (alarm threshold crossed)
Bit 13 = 1 : High alarm active parameter (alarm threshold crossed)
Bit 14 = 1 : Overdose parameter (maximum dosing time exceeded)
Bit 15 = 1 : Empty amount dosing tank
Bit 16 = 1 : Dosing tank empty
Bit 17 à 31 = X : Internal operating information, ‘random’ values
