AIFB function groups
Analog Input Function Block function groups (simulation, mode and status)
Measured values are processed within an Analog Input Function Block to produce the device
output. See AIFB function groups (Page 262). The output is communicated via cyclic transfer to
PROFIBUS PA and displayed on the LCD.
