PLUS+1® Compliant KPP_SPD Speed Sensor Function Block

KPP_SPD Function Block

The KPP_SPD function block outputs an RPM signal that is based on inputs from a KPP speed sensor.

This function block receives its Spd input through MFIn.

Inputs

Inputs to the function block are described.

Input	Type	Range	Description
Para	——	——	Input for a user-defined Pulse/Rev value that defines the number of pulses equal to one
			revolution.
			Optionally, inputs a:
			FaultDetTm value that replaces the function block’s internal default fault-direction time.
			DirLockHz value that replaces the function block's internal default fault direction-lock frequency.
SnsrPwr	——	——	Reports sensor power supply voltage.
Spd	——	——	Speed signal from the speed sensor.

Function Block Parameter Values

The para bus input signals, which set the KPP_SPD function block's operating characteristics, are described.

The input signals of the Para bus set the function block’s operating characteristics. The Puls/Rev value is specified outside of the function block for the specific sensor used. Typically, you do not have to change any of the other values for the correct operation of the function block.

Input	Type	Range	Description
Puls/Rev	U16	1–600	Sets the conversion factor that is used to convert the measured frequency from Hz to RPM.
FaultDetTm	U16	0-65535	Sets the delay time before the function block:
			– Reports a detected fault.
			– Clears a reported fault that is no longer detected.

KPP_SPD Function Block

Outputs

Outputs of the function block are described.

Output	Type	Range	Description
Diag	——	——	Outputs a Diag bus that has a:
			• Para sub-bus.
			• FltTmrFreq signal.
			Also has a Checkpoints page which you can set to enable advanced checkpoint with
			namespace components. This makes all of the function block's input, output, and internal
			signals available to the Service Tool.
Status	U16	——	Reports the function block’s status conditions.
Fault	U16	——	Reports the function block’s fault conditions.
RPM	U32	0–9000000 rpm	The calculated rpm.
			1—1.0 rpm.
dRPM	U32	0–9000000 x .1	Legacy signal, previously labeled RPM in version 1.03 and earlier.
			10—1.0 rpm.

Function Block Connections

Connections you can make with the KPP_SPD function block are described.

Item Description

1Pulses per revolution value.

2Sensor power supply voltage.

3Sensor speed.

4Diagnostic signals.

5Function block status.

6Function block faults.

7RPM output.

8dRPM output.

Using Namespaces

Namespaces can help you successfully compile an application that uses the same function block more than once.

Change each function block's namespace by setting its Namespace value to something unique. If you do not change the Namespace value, you cannot compile the application.
