LS_AnalogInput - analog inputs
9 Internal interfaces
This chapter gives information about the system blocks of the regenerative power supply
module. The system blocks are fixedly integrated in the runtime system and provide the
application in the »Engineer« function block editor with the internal interfaces for the I/Os
and for the device and line interface.
9.1 LS_AnalogInput - analog inputs
The LS_AnalogInput system block represents the analog inputs in the function block
editor.

Value/meaning
AIN1_dnIn_n
DINT
Analog input 1
• Scaling:
±2 30 ≡ ±10 V for use as voltage input
±2 30 ≡ ±20 mA for use as current input
AIN2_dnIn_n
DINT
Analog input 2
• Scaling: ±2 30 ≡ ±10 V
AIN1_bCurrentError
BOOL
Status signal "Current input error"
• Only when analog input 1 is used as current input.
• Application: Cable-breakage monitoring of the 4 ...20 mA circuit.
