Using I/O Camera Devices
If you are using a camera device with digital I/O channels for the process integration MERLIC can be used in machine vision systems that are integrated in a manufacturing machine. The machine controller, e.g., a programmable logic controller (PLC), must be able to control an integrated vision system, to monitor the execution, and to query the results. Therefore, MERLIC provides a process integration mode to enable the communication with a machine controller. The process integration mode can be started with the application "MERLIC RTE" that is provided with the MERLIC installation. mode of MERLIC, you can perform various tasks while MERLIC RTE is running. As soon as MERLIC RTE has been started, it is ready to trigger commands to MERLIC or query results.
The procedures how to check the MERLIC states, execute the MERLIC Vision App, or obtain the results are the same as for digital I/O devices. However, there are some differences which commands are supported. For example, it is not possible to change the recipe via the camera device with digital I/O channels. For more information, see Commands and Signals (I/O Camera).
Make sure that you defined a default MERLIC recipe for MERLIC RTE. When using camera devices with GenICam compliant digital I/O channels, it is mandatory to select a default recipe. For more information, see Defining the Default Recipe
