Analogue inputs: configuration and diagnosis
20881
► Configuration can be carried out via the system variables ANALOGx_y_MODE (
→
Appendix
(
)) or, preferably, via
INPUT_ANALOG
(
) (input MODE). In principle, it is
carried out in pairs:
• ANALOG0 and ANALOG4
• ANALOG1 and ANALOG5
• ANALOG2 and ANALOG6
• ANALOG3 and ANALOG7
If the analogue inputs are configured for current measurement, the device switches to the safe voltage
measurement range (0...32V DC) and the corresponding error bit in the flag byte ERROR_A_INx is set
when the final value (> 23 mA) is exceeded.
>
When the value is again below the limit value, the input automatically switches back to the current
measurement range.
>
When the analogue input FBs are used, the diagnostic function is automatically activated.
>
If for an input channel the limit value is exceeded, switching to the safe voltage range is also done
in pairs:
Example:
ANALOG0 > 23 mA
>
ANALOG0 and ANALOG4 are switched to the safe range 0...32 V DC.
>
The error bit is only set for the incorrect input value.
As an alternative, an analogue channel can also be evaluated binarily.
