MP_RoomSensor_Parameter

This function block is used to parameterize room sensors of types 22Rxx-19-1 that were produced before May 2022 (as of May 2022, see MP_OperatingUnit_Configuration).
For more information, see www.belimo.com.

MP_Address is used to specify the MP-Bus device with which the function block is to communicate. bRead reads the parameters, bWrite writes them to the room sensor. bBusy indicates that the function block is active. bError is used to indicate an error in communication with the actuator. The type of the error can be read with iErrorId.

Name	Type	Description
MP_Address	USINT	MP-Bus address of the slave.
bWrite	BOOL	A positive edge starts the function block and writes the parameter.
bRead	BOOL	A positive edge starts the function block and reads the parameter.
strDataKL6771	DataKL6771	The data structure with which the KL6771() function block must be linked.
bUnitSelTemp	BOOL	FALSE = °C, TRUE = °F.
iOffsetCo2_Write	INT	OffsetCO2 [ppm] -500...500.
rOffsetTemp_Write	LREAL	OffsetTemp [UnitSel] -15...15 °C (-27...27 °F)
rOffsetHumidity_Write	LREAL	OffsetHumidity [%] -20...+20.
rOffsetDewPointTemp_Write	LREAL	OffsetDewPointTemp [UnitSel] -15...15 °C (-27...27 °F).

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.
stUnit	STRING	C = °C or F = °F, ? = not read.
iOffsetCO2	INT	OffsetCO2 [ppm].
rOffsetHumidity	LREAL	OffsetHumidity [%] 0.01.
rOffsetTemp	LREAL	OffsetTemp [°C or °F] 0.01.
rOffsetDewPointTemp	LREAL	DewOffsetTemp [°C or °F] 0.01.
