The registry should resemble the image below.
• Once finished verifying the settings, close the registry. To use PanelScan as a two-camera system, put in both MMF0 and MMF1 . Operation of Memory Mapped Files (MMFs) Memory Mapped Files are created by Visionscape whenever the AVP Backplane runs. The AVP Backplane runs when you start FrontRunner or PanelScan. Important: You must have a Visionscape GigE license key, enabled for third party GigE cameras, installed in the system. The creation of the MMFs is displayed in the Visionscape Debug Window. See the 2nd and 5th lines: There are two ways to acquire an image whenever a new job is created in Visionscape, depending on the PanelScan configuration:
Load Image from VsMemChannel0 for PanelScan Standard and Load Image from VsMemChannel1 for PanelScan Wide. The image below shows an example from Standard. Note that you can create any number of Memory Mapped File channels in the registry so that you can have one per camera. 33 Copyright © 2019 Omron Microscan Systems, Inc.
