Spark Sequence Definition

This MotoHawk™ block sets up a sequence of spark coil drivers, starting with the given pin and working up, one for each driver required by the 'Sequence Type'.

Block ID

Spark Sequence

Library

MotoHawk_lib/Advanced Digital I/O

Description

The input ports may be scalars or vectors, but if vectors, the size must equal the number of cylinders defined by the Encoder Definition block. This number may be calibratable, in which case the vector must be as large as the 'Maximum Number of Cylinders'. When diagnostic outputs are enabled, open and short circuit detection is made available. The Open and Short outputs are one of: 0 - OK 1 - Fault 2 - Indeterminate

The end of a pulse can create a trigger using the PSP End Trigger Block.

Angle inputs are before TDC (BfTDC), in units of 1/16th of degree crank angle. Time inputs are in microseconds. Eg: 730degBfTCD == 10degBfTDC == -710degBfTDC

Angles are converted internally to Mod(angle, DegInCycle). It is therefore not possible to schedule a pulse more than one cycle into the future. When Mod(start - stop,DegInCycle) == 0, angular duration is considered to be zero. For example, this will occur on a 4-stroke when start = 720, stop = 0. To achieve a maximum angle, stop = start - DegInCycle - 1/16.

Block Parameters

Parameter Field	Values	Comments/Description
1st Resource	Drop-down list	Select from available listings, as appropriate, to assign initial pin of sequence.
Sequence Type		Select sequence type from list
	Standard Coil (Coil per Cylinder)	(per cylinder)
	Banked (Fire on both phases until CAM sync)	(per 2 cylinders & half duration)
	Batch (wasted spark)	(per 2 cylinders & half duration & all cylinders)
	Muxed (distributed)
Stop Mode		Select method for Stop
	Angle Controlled	Control Stop Mode by Angle
	Duration Controlled	Control Stop Mode by Time Duration
Update Mode		Select whether to have the OS protect against pulse errors. Only visible for supporting modules (Classic Module Types). Modules that don't support will always use the OS update mode.
	OS	ControlCore protects against missing pulses.
	Application	No error checking is provided, and the application is completely trusted. Not recommended.
Granularity		Select granularity (resolution) as required. Only visible for supporting modules (Classic Module Types).
	Fine	Uses interpolation to schedule angles that fall between encoder teeth.
	Coarse	No interpolation, uses encoder teeth to identify engine position.
Minimum Duration Mode		Select whether to have static or dynamic minimum duration. Only visible for supporting modules (Classic Module Types)
	Static	Select to have constant value, input in mask
	Dynamic	Select to have value calculated in model and input into the block as a signal port.
Minimum Duration (ms)	Numeric	Only visible for supporting modules (Classic Module Types). Any scheduled electrical injector duration smaller than this value is considered to have zero duration when scheduled. Is a member of the mask when the static Minimum Duration Mode is selected and is a signal when dynamic is selected.
Output Spark Diagnostics	Check Box (enable)	When diagnostic outputs are enabled, open and short circuit detection is made available. The Open and Short outputs are one of these: 0 - OK 1 - Fault 2 - Indeterminate
Open-Circuit Threshold [ADC Counts]	Numeric	Set the numeric threshold for ADC counts.
Allow I/O pins to be calibrated	Check Box (enable)	Check to enable calibration, and enable below parameters. This field is only available on Classic modules, see ModuleTypes for help.
Prefix	Alpha-numeric text, single-quote enclosed	Assigns prefix to name. Use "|" character between folder names to delineate subfolder structure.
Read Access Level	0-8	Sets security level 1 lowest, 8 highest, for user access to read value. A setting of zero indicates unsecured access is allowed.
Write Access Level	0-8	Sets security level 1 lowest, 8 highest, for user access to write value. A setting of zero indicates unsecured access is allowed.
Instrumentation Group	Alpha-numeric text, single-quote enclosed	Defines the folder name and hierarchy to be used by a suitable instrumentation tool. Use "|" character between folder names to delineate subfolder structure.
