Inputs

VAR_INPUT
  MP_Address       : USINT := 1;
  bStart           : BOOL;
  strDataKL6771    : DataKL6771;
  TMpolling        : TIME := t#10s;
  bTemp_C_F        : BOOL;
END_VAR

Name	Type	Description
MP_Address	USINT	MP-Bus address of the slave.
bStart	BOOL	A positive edge starts the function block. If this remains continuously TRUE, the function block will be activated cyclically with a period specified by the time in TMPolling.
strDataKL6771	DataKL6771	The data structure with which the KL6771() function block must be linked.
TMpolling	TIME	The time for which the function block should address the actuator. Default 10 s, minimum time 1 s.
bTemp_C_F	BOOL	FALSE = °C / TRUE = F

Outputs

VAR_OUTPUT
  bBusy        : BOOL;
  bError       : BOOL;

  iCO2         : INT;
  iVOC         : INT;
  iHumidity    : INT;
  bFlushStatus : BOOL;
END_VAR

Name	Type	Description
bBusy	BOOL	This bit is set for as long as the function block is active.
bError	BOOL	This output goes TRUE as soon as an error occurs. This error is described via the iErrorId variable.
iErrorId	MP_ERROR	This output outputs an error code in the event of an error. bError goes TRUE at the same time.
strMPX_ERR	MP_BUS_MPX_ERROR	Error messages of the sensors
iU	INT	0…10 V UNIT 1 mV
bDigital	BOOL	DI 24 V
iTemp	INT	0...50 °C Unit:0.01 °C
iCO2	INT	0...2000 ppm Unit:1 ppm
iVOC	INT	0...2000 ppm Unit:1 ppm (pseudo)
iHumidity	INT	10...90 % Unit: 0.01 %
bFlushStatus	BOOL	VOC gradient threshold exceeded, FALSE = air quality OK, 1 TRUE = air quality not OK, flush
