True or False: Every ControlLogix system must consist of at least one analog tag.

In a ControlLogix system, it is not mandatory for the system to include an analog tag. The architecture is flexible and can function with purely discrete tags, which control on/off or binary states. Analog tags, which are used to handle continuous signals and provide more precise control over variable parameters, are only necessary if the system's application requires them.

For example, if the application involves simple on/off device control, such as motors or lights, the inclusion of analog tags would not be relevant. Hence, while some ControlLogix systems may utilize analog tags for specific tasks, they are not a fundamental requirement for every system. This flexibility allows for a variety of configurations, making it possible to design a ControlLogix system entirely without analog tags if the application does not demand it.
