If a ControlLogix consists of a single chassis, it is referred to as what?

In the context of ControlLogix systems, a ControlLogix controller that consists of a single chassis is referred to as a local chassis. This terminology highlights that the components within that single chassis are accessed directly and remain localized to that physical hardware. A local chassis typically houses the CPU, input/output modules, and other necessary components required for the operation of the control system.

The term "local" indicates that all modules and controllers are physically close together in a single unit, as opposed to remote setups, which would involve modules that are located away from the primary ControlLogix system. This distinction is essential in applications where communication speed and system configuration are critical factors. A local chassis provides ease of maintenance and straightforward troubleshooting since all components are integrated into one location. Therefore, recognizing a single chassis as a local chassis is crucial for understanding the configuration and capabilities of ControlLogix systems.
