All of the input and output, status and control tags will have an I/O tab in their tag properties folder.
The I/O tab consists of properties used to identify and establish a connection to the communication driver tag being used to communicate with your physical I/O device. This is accomplished by identifying the communication driver tag, the address at which this basic I/O tag is to read or write data, and the rate at which the I/O device should be scanned for data. A manual data option is provided to allow you to set a constant value for the tag, independent of any actual I/O, for configuration and testing purposes.
Typical I/O tabs for both analog and digital I/O tags:

Digital input tags (including digital status and pump status tags) can have single or double bit addresses. Status tags (analog and digital) will include extra configuration options.
