A Flag point is a two-state (On/Off) point that is used for storing a Boolean value. Flag points are not scheduled and are not processed. Their state is changed from another function, such as by operator input or a user-written program.

Provision is made for up to 16,384 Box Flag points, the first 128 of which can be configured for off-normal alarming.

Numeric points are used for storage of real numbers. They are used for batch/recipe operations, or as a scratch pad to store the intermediate results of calculations.

Like Flag points, they are not scheduled or processed, but are changed as the result of other system activity. There can be up to 16,384 Numeric points.

The Timer point allows for timing of process events by the operator or sequence program. After being started, it provides an indication when the elapsed time has reached a predefined limit. There are 64 timer slots. Each is processed once per second.

The string variable adds increased flexibility to both continuous and batch oriented CL control programs. String variables of 8, 16, 32, or 64 characters can be compared and modified by the APM Control Language (CL). Using CL, you can manipulate and store unique messages that pertain to your process. Also, with this serial interface, ASCII data from a subsystem can be imported and used as string variables, as well as written back to the subsystem. Up to 16,384 eight character strings are supported.

A simple control loop can be implemented in an Advanced Process Manager, using an analog input point, a regulatory control point, and an analog output point.

Although three data points are used, the primary operator interface is a single tag (FC101) for viewing, alarming, and manipulation in the customary manner through a Group, Detail, or Custom Graphic display.
