• FLS window opener
• Flap and positioning actuators (e.g. NM24-MFT2, NV23-MFT2)
• Fire dampers (e.g. BF24TL-T-ST)
• PTH sensors
There is a function block that carries out communication with the device for each of these drives or sensors.
The MP-Bus slave is addressed through an addressing block. The slaves can be addressed manually or
automatically.
Software required for use of the KL6771
TwinCAT PLC has a corresponding library for addressing the KL6771 from within the application.
Note
Required TwinCAT library
TwinCAT supports the KL6771 with its own library.
If the KL6771 is to be used with an external controller, a Bus Terminal controller (BC or BX)
is required on which the MP-Bus library can run. Operation of the KL6771 on a PC or CX
without TwinCAT PLC is not supported!
