Configure a Modbus Register, OPC UA Tag, or PI Historian as a speed
Ensure that you have an Modbus Register, OPC
UA Tag, or PI Historian configured on your asset tree.
The speed reference of an asset allows the server to associate speed values with sensor data for use in calculating spectral
band values. The server determines the speed reference value for an asset by multiplying the reference speed and the speed
ratio for that asset.
Complete the following steps to configure a speed reference.
Configuration button and select a Rotating Equipment (Data Source) or a Wireless Equipment (Data Source) asset.
Speed Properties section, click the
Edit button next to the
Speed Reference field.
Select a Modbus register, OPC UA tag, or PI Historian in the Select
Speed Reference dialog box.
Use the Speed Ratio property of the sensor to set the speed value at the sensor when sensors on an asset run at different
speeds, such as when sensors are located on opposite sides of a gear box. The speed ratio uses the driver:driven format. Numbers
can include decimals but must not include spaces or non-numeric characters.
If the speed reference value is 3600 RPM and the sensor's speed ratio is 2:1, the sensor speed will be 1800 RPM.
