PI SMT
PI SMT refers to PI System Management Tools. PI SMT is the program that you use for configuring PI Servers. A single copy of PI SMT manages multiple PI Servers. PI SMT runs on either a PI Server Node or a interface node.
Pipc.log
The pipc.log file is the file to which OSIsoft applications write informational and error messages. When a PI interface runs, it writes to the pipc.log file. The ICU allows easy access to the pipc.log
Point
The PI point is the basic building block for controlling data flow to and from the PI Server. Fora given timestamp, a PI point holds a single value. API point does not necessarily correspond to a point on the foreign device. For example, a single point on the foreign device can consist of a set point, a process value, an alarm limit, and a discrete value. These four pieces of information require four separate PI points.
Service
A Service is a Windows program that runs without user interaction. A Service continues to run after you have logged off from Windows. It has the ability to startup when the computer itself starts up. The ICU allows you to configure a PI interface to run as a Service.
Tag (Input Tag and Output Tag)
The tag attribute of a PI point is the name of the PI point. There is a one-to-one correspondence between the name of a point and the point itself. Because of this relationship, PI System documentation uses the terms tag and point interchangeably. Interfaces read values from a device and write these values to an Input Tag. Interfaces use an Output Tag to write a value to the device.
