These inputs are logical LS inputs associated with frequency measurement capabilities.
It can be used as general purpose frequency input and is also dedicated to speed sensor input.

This input can be used as:

• Logical Input
• Frequency Input

This configuration is chosen by the parameter 'Mode'.

1 -Logical Input 

1.1 -Characteristics

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

The following mnemonics are available for the logical inputs function:

Mnemonics	STraToN Type	Description
Input_Boo	BOOL	This boolean value give the status of the inputs TRUE for active level FALSE for Inactive level
Threshold_fault	BOOL	This value indicates to the Application that the input is between the two thresholds.
Equipment	BOOL	The usage of the variables of default "Threshold_fault"is not active while the variable connected to this mnemonic has its value to 'False' ( more details ).

2 - Frequency Input

2.1 Characteristics

The valid input frequency range is 0.5Hz to 12kHz

• ON level is: tied to GND
• OFF level is: open circuit

2.2 Parameters

Category	Parameter	Description
General	Time Out	The valid range for this time out is 0ms to 10000ms with a resolution of 100ms.

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

Mnemonics	STraToN Type	Description
Input_Freq_OFF	WORD	The Data TOFF_FREQx value is updated with the OFF state duration measurement. The unit is 1µs. This is a double word variable, it must apply to the double word rule see variable rules
Input_Freq_On	WORD	The Data TON_FREQx value is updated with the ON state duration measurement. The unit is 1µs. This is a double word variable, it must apply to the double word rule see variable rules
Threshold fault	BOOL	This boolean value indicate to the Application that there is not signal available during a time out set by the parameter “Time out”.
Equipment	BOOL	The usage of the variables of default is not active while the variable connected to this mnemonic has its value to 'False' ( more details ).
