MP_Window

MP_Window 1:

This function block is used to control and monitor a window ventilation system (FLS).

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. If bStart remains TRUE, the device is addressed cyclically with a period specified by the time in TMPolling. The time should be set longer than 1 second. bError is used to indicate an error in communication with the FLS. The type of the error can be read with iErrorID.

ManualMode can be used to enable or disable manual operation. The type of ventilation can be specified through WindowSettings.

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.

WindowSettings

Data_Window

Nominal ventilation settings.

ManuelMode

BOOL

FALSE = manual operation permitted, TRUE = manual operation disabled.

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.

MP_Window 3: Outputs

VAR_OUTPUT
  bBusy             : BOOL;
  bError            : BOOL;
  iErrorId          : MP_Error;
  WindowState       : Data_Window;
  Window_Mech_Error : BOOL;
  Memory_Error      : 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.

WindowState

Data_Window

Current ventilation settings.

Window_Mech_Error:

BOOL

The window or actuator is blocked

Memory_Error

BOOL

The actuator has a memory error. Reprogram or replace.
