After successfully simulation resists, we implemented the PID controller into the customer’s application. Then using the LabVIEW Control Design and Simulation Module, Rothenberg Industries created a simulation of the application to design the PID algorithm. Provided the customer with the ability to attain starting PID Gain values to implement in their application.įirst, we created a mathematical model of simultaneously filling and draining a storage tank of cross section A. LabVIEW Control Design and Simulation Module.

The production metrics are to be used for statistical process control via JMP JSL. Upon completion of a run, a VBA script is triggered to analyze the raw data and calculate predefined cycle metrics that are stored a manufacturing SQL database along with the respective production information. The data is continuously written to a *.flat file in real time and stored on a segregated terminal server to preserve partial data if there is any network interruption. The system also includes several real-time alarms such as over-temp and uniformity warnings that are displayed on the corresponding operator panels set from the Microsoft excel configuration file. If the channel type to be acquired is a current or voltage signal, a linear scaling factor is available. The sampling rate can be individually set for each channel as well as the data acquisition start and end value. The data acquisition settings include the Static IP of the ethernet device(s), the individual DAQ modules, the individual channels in the module and signal type (Thermocouple type, Current or Voltage). The system is ergonomically configured from a Microsoft excel file including data acquisition, operator panel, real-time alarm, and post-run KPI settings. During production, the system is interfaced by one or more operator terminals that are run off shop floor computers. A qualified engineer can remote into the terminal server from any location to interface with the central engineering panel. We developed a LabVIEW data acquisition system that continuously runs on a protected networked terminal server that controls multiple ethernet enabled data acquisition devices. The process was to be designed for future scalability regarding operator stations, data acquisition channels and devices. Our client required that their data acquired for thermocouple, current and voltage transducer signals be easily accessible. The system would be interfaced from multiple shop floor computers around the plant and from a central engineering panel. Our client has dozens of manufacturing furnaces and hydraulic presses that require data acquisition with traceability down to the individual component serial number.
