Keyence permits FTP to export pictures in numerous codecs, however when exporting graphics, the system outputs the bottom picture file and a separate .SVG overlays file.
Ignition couldn’t interpret the SVG overlays, that means it couldn’t show the annotated pictures. As a workaround, we displayed the digicam’s hosted webpage contained in the Ignition HMI. Another would have been to construct all graphical overlays instantly in Ignition, however time constraints made that impractical.
The lesson right here is to think about how you plan to make use of pictures downstream early within the course of.
Assessing the imaginative and prescient system improve
Total, the Keyence VS-Sequence proved to be a robust alternative for the growing old customized imaginative and prescient system. The VS Creator platform was intuitive, particularly the Imaginative and prescient Dashboard, and simulation instruments considerably accelerated improvement earlier than {hardware} even arrived. Troubleshooting is now far simpler with out counting on a compiled VB.NET software, and PLC communication was seamless utilizing Keyence’s offered information.
Whereas the image-export limitations required artistic workarounds, the core imaginative and prescient instruments, calibration capabilities and programming atmosphere made the combination clean and maintainable.Â
