Advanced > SPC protocol

Trigger source — Trigger source for SPC transmission

Dependencies

This parameter appears only if you select the SENT Protocol parameter as SPC.

Source of hardware trigger — Source of hardware trigger for SPC transmission

GTM - TOM0 (default) | GTM - TOM# | GTM - ATOM# | EGTM - TOM# | EGTM - ATOM#

Select the source of hardware trigger for SPC transmission.

Note

The rising edge of the hardware trigger activates the SPC pulse.

The Sent trigger signal depends on the choice of Source of hardware trigger parameter. The available sent trigger signals for different combinations of timer module, timer submodule and timer unit are:

Module	Timer unit	Sent trigger signal
eGTM	TOM0/ATOM0	Sent_TriggerSignal_0
	TOM1/ATOM1	Sent_TriggerSignal_1
	ATOM2	Sent_TriggerSignal_2
GTM	TOM0/ATOM0	Sent_TriggerSignal_3
	TOM1/ATOM1	Sent_TriggerSignal_4
	TOM2/ATOM2	Sent_TriggerSignal_5
	TOM3/ATOM3	Sent_TriggerSignal_6
	TOM4/ATOM4	Sent_TriggerSignal_7
	TOM5/ATOM5	Sent_TriggerSignal_8

	ATOM7	Sent_TriggerSignal_10
	ATOM8	Sent_TriggerSignal_11
	ATOM9	Sent_TriggerSignal_12
	ATOM10	Sent_TriggerSignal_13
	ATOM11	Sent_TriggerSignal_14

Dependencies

This parameter appears only if you select the Trigger source parameter as Hardware trigger.

Sensor count — Specify sensor count

1 (default) | 1 to 4

Specify sensor count for sensor selection.

This parameter decides the number of SPC pulses to configure in the sensor selection mode.

Dependencies

This parameter appears only if you select the SPC Mode parameter as Sensor selection.

Pulse length # in ticks — Pulse length for SPC pulse #

0 (default) | 0 to 63

Specify pulse length for SPC pulse #.

Note

• You can configure up to 3 SPC pulses if you set the SPC Mode parameter as Feature selection.

• You can configure up to 4 SPC pulses (based on Sensor count parameter) if you set the SPC Mode parameter as Sensor selection.

• You must specify a value at the DataSel input port within the range of 1 to 4 depending on the SPC Mode parameter. If you provide a DataSel value outside this range, the block will, by default, consider the pulse length values for the out-of-range SPC pulse as the value provided at the Pulse length 1 in ticks parameter.

Dependencies

This parameter appears only if you select the SENT Protocol parameter as SPC.

Pulse- # delay length in ticks — Pulse delay for SPC pulse #

0 (default) | 0 to 63

• You can configure up to 4 SPC pulses (based on Sensor count parameter) if you set the SPC Mode parameter as Sensor selection.

• You must specify a value at the DataSel input port within the range of 1 to 4 depending on the SPC Mode parameter. If you provide a DataSel value outside this range, the block will, by default, consider the pulse delay value for the out-of-range SPC pulse as the value provided at the Pulse- 1 delay length in ticks parameter.

Dependencies

This parameter appears only if you select the SENT Protocol parameter as SPC.
