MP_OperatingUnit_ConfigurationVentilation

This function block is used to configure room sensors of types P-22Rxx-1900x-1. It is compatible with 22Rxx-19-1 room sensors produced as of May 2022 (before May 2022, see MP_RoomSensor_Parameter).
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. bStart activates communication with the MP-Bus device. 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.

Inputs

VAR_INPUT
  MP_Address                   : USINT := 1;
  bStart                       : BOOL;
  strDataKL6771                : DataKL6771;
  fVentilationStage            : LREAL;
  nSystemOperationMode         : E_MP_SystemOperationMode;
  bVentilationStageControlMode : BOOL;
  nDisplayModeVentilationStage : E_MP_DisplayModeVentilationStage := MPBus_DisplayModeVentilationStage_7;
  bVentilationControlMode      : 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.
fVentilationStage	LREAL	Ventilation stage in the room/zone in % (0...100).
nSystemOperationMode	E_MP_SystemOperationMode	Operation mode of the system
bVentilationStageControlMode	BOOL	Mode of ventilation stage control. Applies if bVentilationControlMode is set to TRUE.
nDisplayModeVentilationStage	E_MP_DisplayModeVentilationStage	Display mode of the ventilation stage.
bVentilationControlMode	BOOL	FALSE = manual mode only; TRUE = hybrid control mode (setpoint invisible in auto mode).

Outputs

VAR_OUTPUT
  bBusy                  : BOOL;
  bError                 : BOOL;
  iErrorId               : MP_Error;
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.
