Abstract
A disclosed example system includes a termination panel, and a shared bus on the termination panel. The shared bus is to removably receive a plurality of bases that removably receive modules to communicate with field devices, and communicatively couple the modules to an input/output card to exchange communications between the modules and a controller that is in communication with the input/output card via a second bus.
Claims15
A system, comprising:
- a termination panel;
- and
- a shared bus on the termination panel, the shared bus to:
- removably receive a plurality of bases that removably receive modules to communicate with field devices, and
- communicatively couple the modules to an input/output card to exchange communications between the modules and a controller that is in communication with the input/output card via a second bus.
2 more elements
A method, comprising:
- determining whether modules are connected to correctly corresponding field devices based on field device identifiers stored in an input/output card in communication with the modules;
- and
- exchanging communications between the modules and a controller, the modules in communication with a shared bus via corresponding bases removably coupled to the shared bus, and the communications exchanged via the input/output card in communication between the shared bus and the controller.
