Press Release Summary:
HMI Controls VS 720 display and process images from Simatic VS 720 vision sensors. Along with central operation, they enable visualization of live images, analysis of faulty test objects, display of image analyses, and archiving of results. Products utilize MS DCOM and ActiveX technologies and can sequentially display images from up to 4 vision sensors, differentiated according to good or fault. Up to 20 values can be displayed per vision sensor.
Original Press Release:
Simple Operation and Monitoring of Image Processing Systems
Images from the Simatic VS 720 vision sensors can now be simply displayed and processed using HMI (Human Machine Interface) systems. Siemens Automation and Drives (A&D) has developed so-called HMI Controls VS 720 for this purpose. These permit central operation, visualization of live images, analysis of faulty test objects, display of the image analyses, and archiving of the results for one or more vision sensors.
HMI Controls VS 720 utilize the Microsoft DCOM and ActiveX technologies, and have been specially designed for Simatic Multi Panels and PC-based solutions with the WinCC and ProTool/Pro visualization systems. They are integrated into the visualization system like standard HMI functions. Connected via Industrial Ethernet to the HMI system, the vision sensors transmit live images to the HMI Controls. Images from up to four vision sensors can be displayed sequentially, and differentiated according to "good" or "fault". Test criteria which are additionally displayed for faulty images facilitate fault analysis. Images are saved in a ring buffer which is overwritten cyclically, for example until a faulty test object stops the sequence. In addition, all images can be sequentially saved with consecutive numbers and time/date stamp to permit later evaluation.
Up to 20 values can be displayed per vision sensor, and archived if required. The archived data are simply exported in a CSV (Comma Separated Values) file and subsequently processed further. The HMI Controls VS 720 also have functions for remote operation, for example to display active test programs of the vision sensor or to load new test programs.
In the second delivery stage, recorded values are simply converted into an HMI variable and displayed by the HMI signaling system, for example to generate graphs and recognize trends. In addition, test programs are saved centrally on the HMI unit.
