Analog Control Tags

 It is the role of analog control tags to transmit analog data entered by the user to an I/O device. An analog control tag might be used to change the speed of a motor, or to specify a feed time for chemicals to be added to a well or tank.

In most cases, an operator will use the control tag to write information out to the system. You also have the option of configuring an automatic data source such as a calculation tag to provide the information that is to be written.

The characteristics of analog control tags are summarized in the table below.
