摘要： An interface module includes a high density analog interface (HAI) for electrical interconnection between a programmable logic controller (PLC) and an analog to digital converter (ADC) or a digital to analog converter (DAC). The HAI includes a single application specific integrated circuit having a data scaling function block, a diagnostics function block configured to verify functionality of said scaling function block, a self-calibration function block configured to compensate for drift in said ADC, and a shared interface function block configured to electronically connect said module with a programmable logic controller (PLC).

摘要： A method, apparatus, and system for controlling a process are provided. The control device apparatus includes an input section configured to receive input signals from a controlled process, a first output section communicatively coupled to the input section wherein the first output section is configured to transmit the received input signals to a controller, and a second output section communicatively coupled to the controller, the second output section is configured to transmit control signals from the controller to the controlled process. The apparatus further includes a safety logic block communicatively coupled to the input section in parallel with the received input signals that are transmitted to the controller, the safety logic block is configured to generate a safety output signal using the received input signals, the safety logic block is further configured to transmit the safety output signal to the controlled process independent of the control signals.
