Abstract: 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.
