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.

PLUS+1® Compliant KPP_SPD Speed Sensor Function Block
KPP_SPD Function Block
The Namespace value adds a unique prefix to each component name.
Also, if you want to use these function blocks' companion Service Tool screens, you must include the
function block's advanced checkpoint with namespace in the application's compiled .lhx file. Use the
function block's Checkpoints page to include the checkpoint.
Change Namespace Value
To successfully compile your application, change the namespace value for function blocks that are used
more than once in an application.
1. In the PLUS+1® GUIDE menu bar, click the Query/Change button.
2. Click on the function block whose namespace you want to set to a unique value.
The Edit Page window opens.
3. In the Edit Page window, enter a meaningful Namespace value.
Namespace values are case-sensitive.
•
To save controller memory, use a short namespace value.
•
4. Press Enter.
5. Repeat these steps to enter unique namespace values for other identical function blocks.
Include Advanced Checkpoint with Namespace in Compiled Application
Make all of a function block's input, output and internal signals available to the Service Tool.
Each function block has an Advanced Checkpoint with Namespace page that you can edit to ensure
unique namespaces are included in the application's companion screens for the Service Tool.
1. Enter the function block.
2. On the Checkpoints CP page, ensure the Chkpt signal is set to T.
3. To set the value to true:
a) Select the chkpt signal.
The Edit Value window opens.
b) Select T from the drop-down menu.

KPP_SPD Function Block
Status and Fault Logic
Use status and fault codes to determine proper program operation. The function block does not use
standard status and fault codes.
Status Logic
The status code indicates the calibration state of the function block.
Status Bit*Reported While
Invalid setup/calibration 4 The Input Para bus Puls/Rev signal has been assigned a value outside a range of 1–600.
*
Position of set bit in a 16 bit status or fault code. Bit 1 is the least significant bit.
Fault Logic
A frequency input signal is compared with sensor power voltage to detect faults.
The voltage level of the frequency input signal is measured as a percent of sensor power voltage. This
measurement is used to detect faults.
The function block detects and reports fault conditions and applies constraints. The sensor power and
frequency range fault conditions in this block are reported immediately upon detection and clear
immediately when the condition is no longer detected.
Frequency signal faults are detected while Freq = 0 or when Count = 0. (The bus routed to the function
block’s Spd input contains the Freq and Count signals.) Detected faults are reported in the Fault output
value from the time the count reaches FaultDetTm until it counts back down to zero.
Problems that can occur in the function block are described in the table that follows, along with potential
solutions to these problems.

Fault Reporting Examples
Use the examples that follow to learn more about how the function block detects and reports faults.
Speed Sensor 1 Fault Detection
This example shows how a set of five faults is reported using a fault timer.
The fault timer counts up to FaultDetTm while any fault in the set is detected. The fault time counts
down to zero while no fault in the set is detected.
Speed Sensor 1 Fault Detection
Speed Sensor 2 Fault Detection
This example shows how a set of three faults is reported for each input signal, with each signal using its
own fault timer.
The fault timers count up to FaultDetTm while any fault in the set is detected and counts down to zero
while no fault in the set is detected.

Speed Sensor 2 Fault Detection
Unlike speed sensor 1 faults, speed sensor 2 faults do not distinguish between a ground fault, a signal
fault, or a power lead open fault. If you get one of these faults, check all three leads to determine which
lead is causing the fault.
