6.2.23 MP_Window
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 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 .
ManuelMode can be used to activate or deactivate manual operation. The type of ventilation can be
specified through WindowSettings .
