Embodiment Construction

[0015] figure 1 It is a block diagram of an exemplary actuator interface module 100. In this exemplary embodiment, the module 100 is a circuit card. Alternatively, the module 100 has any configuration that facilitates execution of the operations of the module 100 as described herein. The module 100 includes at least one embedded controller 102. The controller 102 includes firmware 104. The firmware 104 is configured to implement at least a part of the control logic (not shown) associated with the module 100 and to facilitate interface communication. In an exemplary embodiment, a programming language is used to configure the control logic in a manner substantially similar to a typical programmable logic controller (PLC) ladder logic, and the programming language includes at least a portion that can be downloaded from Charlottesville, Virginia. Commercially acquired by GE Fanuc Automation North America Machine Edition LogicDeveloper-PLC, but not limited to this. Alternatively, as...

Abstract

A method and an apparatus for easying logic control and interface communication. A method of distributing programmable control logic includes embedding substantially all of at least one programmable control logic scheme within at least one field device. A field device interface is embedded within the field device that includes firmware configured to facilitate execution of at least a portion of a programmable control logic scheme. The programmable control logic scheme is substantially contained within the firmware. The at least one field device forms at least a portion of a sensor actuator control network (SAC Net) that also includes at least one embedded actuator interface module and at least one embedded sensor interface module. Each of the modules include at least one of the field device interfaces embedded therein. The method also includes providing at least one logical input to the at least one programmable logic control scheme over at least a portion of the SAC Net.

Description

Technical field [0001] The present invention relates generally to logic control, and more specifically, to embedded programmable logic control and interface communication. Background technique [0002] Many known distributed programmable logic control systems include multiple programmable logic controllers (PLCs) or other processor-based configurations or solutions, including distributed control systems (DCS), but are not limited to them. Typically, a PLC-based distributed programmable logic control system has hardware and software components. For example, many of these PLC-based distributed control systems are used to manage individual parts of the workplace to control individual components, small processes or subsystems. PLC is also used in extended industrial control system applications to provide coordinated control of equipment, equipment, systems, and processes. A PLC usually includes a central processing unit (CPU) and a plurality of input / output (I / O) modules with I / O con...
