Frequency Input can operate in two different Mode edit by the parameter "Mode" :

Logical Input : input used in logical mode.

Frequency Input: Frequency Input is used.

1-1 - Parameters Description

Except the Mode parameter, there is no other configuration needed for the input in logical mode.

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 it is set to 1 when the input is active and reset to 0 when it is inactive. The status evolution is shown in the following hysteresis where: V1 and V2 are threshold values set by manufacturing parameters. using High side or Low Side is set by manufacturing parameter. For HS configuration :
		For LS configuration :
Equipment	BOOL	To manage the Fault detection ( more details ).
