Follow on Google News | Highly Accurate Die Casting Process Control SolutionBy: CAS DataLoggers CAS DataLoggers supplied the data acquisition and control solution for a prominent manufacturer of die-cast presses. These presses used hydraulic systems to force molten metal into a die, forming intricately- Installation CAS DataLoggers provided the solution that incorporated an ADwin-Gold Real-time Data Acquisition and Control System (https://www.dataloggerinc.com/ This 16 analog input channel system measuring at 18-bit resolution was then connected to various sensors to effectively monitor the pressure, force, speed and displacement during the injection shot. Usage The ADwin-Gold system's local real-time CPU supported parallel, individually- The ADwin application runs on the processor internal to the ADwin hardware. It is accessible by applications on computers running Windows, Linux, Mac iOS and other platforms. Multiple PCs communicated with the ADwin-Gold concurrently during program implementation and commissioning, and when necessary, one PC could also access multiple ADwin systems, as part of a network to provide centralized monitoring. The system also enabled calibration of the system's analog inputs and outputs and had drivers for many popular programming environments including VB, VC/C++, LabVIEW, Kakkiste and others. The ADbasic application was created using the ADbasic development environment With ADbasic, users defined the processing sequences executed on the ADwin hardware, optimizing and compiling the program code with just a click of the mouse. The system's real-time processes executed independently after being loaded on the ADwin-Gold via ADbasic or a graphical PC user interface. ADbasic also contained the functions to access all inputs and outputs as well as those for floating-point operations, process control, and PC communication. Users also had a library containing standard functions such as for filtering, various examples for counter use, function generators etc., which helped them to quickly implement the program. ADTools offered a simple way for users to view their real-time data graphically or numerically to visualize process sequencings or to set input values via potentiometers, sliders, or push buttons. Additionally, ADtools constantly provided the current status of the ADwin system's resources. Benefits The manufacturer's shot injection process was effectively monitored and controlled following installation of the ADwin-Gold data acquisition system. The ADwin provided highly accurate, die casting process control in real-time and was easily customized to provide special functionality, resulting in faster, and more accurate performance than was possible using conventional PLCs. Operators used a Windows-based PC for the HMI to greatly simplify connection to the factory network for monitoring, recipe management, and process feedback—this oversight gave users the split-second response times needed to ensure the correct part density and porosity. Additionally, data transmission and accessibility were greatly simplified via the system's flexible communications capabilities. The project is one of the many applications of control systems possible with ADwin.
