ActiGRAF Help : MULTIC2 Input with Threshold Description



The configuration of the input on HS or LS is done by manufacturing parameter.

1 - Parameters Description

Parameter Description
Filter define the filtering value for the Logical input. the filter unit is Ms.
When programming the ECU a resolution of 50 Ms is used, hence the increment unit is 50.
High threshold Define the high threshold for failure detection. The threshold's unit is mV. A resolution of 10mV is used to pass the value to the ECU.
Low threshold Define the low threshold for failure detection. The threshold's unit is mV. A resolution of 10mV is used to pass the value to the ECU.


2 - Mnemonics Description

The mnemonics names for ECU IO must applies a set of rules more details.

Mnemonic STraToN Type Description
Input_Boo BOOL Indicate the status of the input, the status evolution is shown in the following hysteresis:

  • For HS configuration :
    Input Boo Status for HS
  • For LS configuration :
    Input Boo Status for LS
  • Fault BOOL If the analogue value of the input is in the range defined by Low Threshold and High threshold, the Fault variable is set to 1. Otherwise it is null. This variable must use a specific naming see variable rules.
    Equipment BOOL To manage the Fault detection ( more details ). This variable must use a specific naming see variable rules.
