Analogue inputs: configuration and diagnosis

Configuration of each input is made via the application program:
• FB INPUT
(
→ p.
169 ) > input MODE
► If the analogue inputs are configured for current measurement, the device switches to the safe
voltage measurement range (0...32 V DC) and the output RESULT is set accordingly in the
function block INPUT when the final value (23 mA for > 40 ms) is exceeded. After about one
second the input automatically switches back to the current measuring range.
As an alternative, an analogue channel can also be evaluated binarily.
