Easy integration with Cognex vision systems
Traditional vision inspection systems often do not allow direct integration into the machine control system (PLC). However, some vision systems have inputs that allow the PLC to send a trigger and outputs for transmitting signals back to the PLC indicating whether the product has passed inspection.
While this basic interaction may have been sufficient in the past, today’s vision applications are much more complex. Oftentimes there are multiple steps within the inspection process that are evaluated as a whole to determine whether a product has passed or not. If a product has not passed it is especially important to know exactly which step in the inspection has failed.
