ActiGRAF Help : MASTER25 Universal Input Description

MASTER25 has three Universal Inputs that can be configured either in analogical or logical mode. For these inputs, the Mode parameter can take one of the following four values :

- Logic LS: input used in logical mode.
- Logic HS: input used in logical mode.
- Analogic resistor: input used in analogue mode.
- Analogic voltage : input used in analogue mode.

### 1 - Logical Mode

##### 1-1 - Parameters Description

Parameter | Description
--- | ---
Filter Value | The filtering value gain is adjustable between 5ms to 480ms.
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.

##### 1-2 - 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 :
- For LS configuration :
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.
Equipment | BOOL | To manage the Fault detection ( more details ).

### 2 - Analogue Mode

##### 2-1 - Parameters Description

Parameter | Description
--- | ---
Filter Value | The filtering value gain is adjustable between 5ms to 480ms.
High Threshold | For Resistor Mode: Defines the high threshold for failure detection. The threshold's unit is 1 ohm.
For voltage Mode: Defines 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 | For Resistor Mode: Define the low threshold for failure detection. The threshold's unit is 1 ohm.
For Voltage Mode : Defines 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.

##### 2-2 - Mnemonics Description

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

Mnemonic | STraToN Type | Description
--- | --- | ---
Input_AnaV4 | WORD more details | Indicates the value of the input, the value is read over 4 bytes. The value is given in 0.01 Ohm for resistance configuration and 1mV for voltage configuration.
Fault | BOOL | indicates Fault detection. If the analogue value of the input is out of the range defined by Low Threshold and High threshold, the Fault variable is set to 1. Otherwise it is null.
Fault_Type | BOOL | Indicates whether the value is over the High Threshold or under the Low threshold. The following hysteresis show the variable changes, switch the analogue value:
Equipment | BOOL | To manage the Fault detection ( more details ).
