FB_BA_SunBldSwi

With the help of the function block FB_BA_SunBldSwi the blind actuator FB_BA_SunBldActr or the roller blind actuator FB_BA_RolBldActr can be controlled in manual operation mode. The connection takes place via the positioning telegram ST_BA_Sunbld either directly or with an additional priority control.

Operation

In manual mode, the function block controls the blind function block FB_BA_SunBldActr or the roller shutter function block FB_BA_RolBldActr via the command inputs bUp and bDwn; bUp has priority. The commands are passed on to the respective commands bManUp and bManDwn of the positioning telegram. If a command input is activated that is longer than the entered time nSwiOvrTi [ms], then the corresponding control command latches. Activating a command input again releases this latch.
If the function block is activated by input bEn = TRUE, bit bActv is set immediately in the positioning telegram. The function block uses this to indicate its priority over low priorities at the priority switch (see ....). At the same time, the bit bManMod is set in the positioning telegram to notify the connected actuator function blocks that they should respond to manual commands.

If the function block is deactivated by bEn = FALSE, both bits, bActv and bManMod, are set to FALSE again.

Linking to the blind function block

The manual mode function block can be connected either via an upstream priority control FB_BA_... or directly at the blind function block. The connection is established via the positioning telegram ST_BA_Sunbld.
