Configure I/O rate tag

Note: For information on overriding default configuration settings, refer to Modify configuration settings.

An I/O rate point can be configured to receive 10-minute averages of the total number of exceptions per minute that are sent to the PI Server by the PI-OASyS interface. This does not apply to a value that has passed the exceptions for a given point.

To configure I/O rate tag

1. In the PI Server node, configure the PI Tag.

2. In the PI-OASyS interface node, assume the name of the I/O rate point is inf001.

3. Edit/Create a file called iorates.dat in \Program Files\PIPC\DAT directory.

4. Add the following line to the iorates.dat file:

   :inf001, x

   Where:

   • inf001 = the name of the I/O rate point.

   • x = the "EventCount" key defined in the PIOASYS.json file.

     Note: The PI-OASyS interface must be stopped and restarted in order for the I/O rate tag to take effect. I/O rates will not be written to the tag until 10 minutes after the PI-OASyS interface is started.

5. Check the PI-OASyS interface node clock and the server node clock. They should be synchronized.

6. Ensure that the time and time zone settings on the PI Server node computer and the PI-OASyS interface node computer are correct.

   Example: Create an I/O Rate Tag with the following point attribute values.

   Attribute	Value
   PointSource	O
   PointType	Float32
   Compressing	0
   ExcDev	0
   exdesc	[UI_IORATE]
