FB_BA_LightActrAnalog
The function block FB_BA_LightActrAnalog is used to control an analog light actuator.
The output is in 0...100% and converted accordingly in 0...32767 (positive integer range). The function block is thus suitable for use with the dimmer terminals (e.g. KL2751, KL2761).
Function
If the function block is not enabled (bEn = FALSE ) the outputs fActlLgtVal = 0 and iActlLgtVal = 0.
In the enabled state the light brightness value of the input telegram (stLightingCmd.fLgtVal) is passed directly to the output fActlLgtVal. The same value multiplied by 327.65 is given to the output iActlLgtVal.
