numerator_update

Set to 1 if the numerator for this DTE is to be updated, set to zero otherwise. The block responds to a rising edge on this inport. This is used by the block to increment the specific numerator for the DTE. Note that the DTE specific numerator will be incremented only once per drive cycle. Therefore, it is important that this inport is returned to level 0 before a new drive cycle event, if a numerator update is not required. The signal passed to this inport should be connected to all DTEs which contain the same Monitor identifier in order that the specific numerator is updated simultaneously for all those DTEs.

Range: 0 or 1

denominator_update

Set to 1 if the denominator for this DTE is to be updated, set to zero otherwise. The block responds to a rising edge on this inport. This is used by the block to increment the specific denominator for the DTE. The user should set this inport to 1 only when every monitoring condition necessary for the monitor of the specific component to detect a malfunction and store a pending fault code has been satisfied. Note that the DTE specific denominator will be incremented only once per drive cycle. Therefore, it is important that this inport is returned to level 0 before a new drive cycle event, if a denominator update is not required. The signal passed to this inport should be connected to all DTEs which contain the same Monitor identifier in order that the specific denominator is updated simultaneously for all those DTEs.

Range: 0 or 1

test_value

The test value collected during the test.

Range: [0, 65535]

test_limit_min

The threshold which the test value must be above in order to pass the test.

Range: [0, 65535]

test_limit_max

The threshold which the test value must be below in order to pass the test.

Range: [0, 65535]

test_run

Sets whether the test has been run at this time step.

When this input is 1, the block sets the test value and min and max limits for the DTE to the values on inports test_value, test_limit_min and test_limit_max respectively. When this input is 0, the stored test value and min and max limits are held unchanged. Note that this input is level-triggered and not edge-triggered. This is required so that results for continuously-monitored tests such as range checks on sensors may be updated at every step.

Range: 0 or 1

reset

Sets whether the test is to be reset at this time step.

Set to 1 to cause the block to reset the test value, test min and test max for this DTE to initial values of 0 and its test run status to 'test not run'. Set to 0, otherwise. Note that this input is level-triggered and not edge-triggered. This is required so that test results may be repeatedly reset if necessary. Note also that test_run takes precedence over this input.

Range: 0 or 1

dte_numerator

The specific numerator for this DTE. Used internally for calculation of the DME's In-Use performance ratio which this DTE belongs to.

Range: [0, 65535]

dte_denominator

The specific denominator for this DTE. Used internally for calculation of the DME's In-Use performance ratio which this DTE belongs to.

Range: [0, 65535]

numerator_updated_this_dc

Set to 1 if the specific numerator for this DTE has been updated this drive cycle, set to 0 otherwise.

Range: 0 or 1

denominator_updated_this_dc

Set to 1 if the specific denominator for this DTE has been updated this drive cycle, set to 0 otherwise.

Range: 0 or 1

dte_test_value

The test value that the platform holds for this DTE.

Range: [0, 65535]

dte_test_limit_min

The test minimum threshold that the platform holds for this DTE.

Range: [0, 65535]

dte_test_limit_max

The test maximum threshold that the platform holds for this DTE.

Range: [0, 65535]

dte_test_run_status

The test run status that the platform holds for this DTE. A value of 0 indicates that the test has never run. A value of 1 indicates that a test has run on this drive cycle. A value of 2 indicates that a test has run but not on this drive cycle.

Range: [0, 2]

DTE identifier

The unique identifier for this DTE.

Range: [0, 255]

DME identifier

The identity of the DME that this DTE belongs to. For example, an Exhaust gas sensor monitor will have a subset of DTEs. This DTE needs to have a matching DME identifier parameter with its parent DME.

Range: [0, 255]

ISO Type?

If this box is checked then the parameters pertaining to ISO specific DTEs are available. Note that a DTE can be ISO type, J1939 type or both.

Range: 0 or 1

Monitor identifier

The ISO-15765 monitor identifier (OBDMID - see J1979 spec dated Sept 2010 appendix D) that this DTE belongs to. It is used for reporting over ISO-15765 diagnostics in response to service $06. Only available if the ISO Type? option is checked.

Range: [0, 255]

ISO scaling identifier

This identifier is used to reference the scaling and unit to be used by the external test equipment in order to calculate and display the test values (results), Minimum Test Limit, and the Maximum for the DTE. Only available if the ISO Type? option is checked.

Range: [0, 255]

ISO test identifier

The ISO specific test identifier (TID). Only available if the ISO Type? option is checked.

Range: [0, 255]

J1939 Type?

If this box is checked then the parameters pertaining to J1939 specific DTEs are available. Note that a DTE can be ISO type, J1939 type or both.

Range: 0 or 1

J1939 test identifier

The J1939 specific test identifier (TID). See J1939-73 Sept 2010 section 5.7.7.1 for details. Only available if the J1939 Type? option is checked.

DM10 bit position

This is the bit position to set in a requested DM10 message response, to indicate test supported. Refer to J1939-73 FEB2010 section 5.7.10 for details. The assignment of a given test identifier (as provided in the J1939 test identifier parameter) to a given bit position is manufacturer specific. This parameter is optional and may be left blank, in which case the DM10 bit position will default to the value provided in the J1939 test identifier parameter, provided it lies in the range specified below. Only available if the J1939 Type? option is checked.
