6.1.5 Connection of the "Analog I/O" module for active usage
• In the active usage the supply voltage for the communication line is supplied by the
device itself. There is no need of an external power supply.
• The wiring must be in accordance with the intended operating mode of the Analog
I/O module (→  196); see the drawings below.
"Operating mode" = "4..20mA output" or "HART slave +4..20mA output"
