Programming and Control Examples
HPF-300
This machine is designed to clean diesel injection system fuel rails using high pressure oil and air. Controlled by a PLC, a flushing sequence is constructed in Excel, or directly on the machine, to clean a component in the most efficient manner. An Excel spreadsheet has been created with various controls to assist in the correct creation of the sequences. Existing sequences may be copied from the machine for editing offline and then reloaded using a memory card. Run time information about the machine status is displayed to the operator via the HMI screen.
NCV Test Machine
This machine is designed to carry out multiple dynamic tests on an injection system component. It is a robot loaded machine picking from, and placing to, pallets of up 25 components. The Robot control interacts with the data acquisition system reacting and responding to test information about the components. All test information is recorded against a unique identification located on the component and stored on a central networked database. Operator feedback is via an HMI designed specifically for this machine using HP Vee. The run time screens are operator selectable giving access to different information, while in-sequence SPC analysis is carried out on each test result. Test parameters and new products are edited and created offline using Excel and then imported into the machine control.
Pneumatic Test Rigs
These machines are designed to test pneumatic components. The entire control, data acquisition and user interface are written in Visual Basic along with the historical data handling and manipulation features. All aspects of these applications were tailored to the exact requirements of the customer and the features provided designed to function exactly as requested. Machine diagnostics in the form of a representation of the system and meaningful operator messages make for intuitive fault finding. The flexibility of Visual Basic means any number of proprietary data acquisition products may be used to accomplish the job requirements. The entire control, data acquisition and result manipulation are carried out on a single P.C.
