[0060] Temp 0: Temp0 is a local variable used in the data concentrator PLC8 logic, which references coefficient 0 in the configuration download array. Temp# ranges from 0 to 150 for some CDAs. The Temp row in the CDA example has the Temp# or coefficient for each column used in the logic. Factors 0...150 contain real world input or output positions.

[0061] Unselected: is the reference position in the MA.Bit (main bit) array of the configuration tool stored in the coefficients, where the coefficients in the logic are not selected or not needed or not used. If the reference position of the coefficient is 0, the state of position 0 in the MA.Bit array is always 0. The state of position 1 in the MA.Bit array is always 1 if the position of the coefficient is 1. The v...

Abstract

The present invention provides an automated configurable control system (CCS) for a manufacturing process system, which permits a user to address menus on screen images for initially configuring the process, and for subsequently rapidly adding, modifying, and deleting components and control signals, without revising software programs. The control system utilizes a configuration tool for automatically providing a configuration database file from data inputted by a user into the CCS. A deployment tool automatically downloads the configuration database file to a SCADA application responsive thereto for defining the system, monitoring the status of the processing system, and displaying screen images. The deployment tool also provides the data via a download application to a PLC application for defining the objects and logic of the processing system.

Description

technical field [0001] This invention relates generally to systems for controlling and monitoring manufacturing processes, and more particularly to such systems that can be configured with minimal software changes. Background technique [0002] Currently, manufacturing monitoring and control systems make it possible to add elements or devices to the process system being monitored and controlled, but such new added elements or devices are located in fixed logic and / or input / output (IO) configurations . To operate outside the fixed structure provided, the user must modify the software in the monitoring and control system. For this, skilled software engineers are usually required, and the required code is often complex, monotonous, and difficult to debug. Therefore, in order to overcome these problems in the prior art, people have always hoped to develop a monitoring and control system that enables users to flexibly and conveniently perform target definition when configuring ...
