PLUS+1® Compliant KPP_SPD Speed Sensor 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 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. |
|
|
|
|
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 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. |
|
|
|

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.
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.
