Device/input simulation

You can define a simulated value to be input to the AIFB instead of the output value from the
Transducer Block. The simulated value allows the AIFB to be tested independently of the
characteristics of the environment.
Actual Mode: Device / Output Simulation
Actual Mode allows you to select one of three possible outputs.

AIFB function groups

D.9 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 198). The output is communicated via cyclic transfer
to PROFIBUS PA and displayed on the LCD.
