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.

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
1 Pulses per revolution value.
2 Sensor power supply voltage.
3 Sensor speed.
4 Diagnostic signals.
5 Function block status.
6 Function block faults.
7 RPM output.
8 dRPM 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.
