Starting and Stopping MERLIC RTE

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 can be started via the application MERLIC RTE MERLIC RTE (Runtime Environment) is the name of the application that is used to start MERLIC in process integration mode. It can be started either via the Windows start menu or via the command line with the executable "merlic_rte.exe". which is provided with the MERLIC installation. There are different ways to start MERLIC RTE: via the start menu (on Windows systems), via the MERLIC RTE Setup, and via command line.

When starting MERLIC RTE via the Windows start menu or the MERLIC RTE Setup, the Frontend of the respective MERLIC Vision App (MVApp) will also be started automatically. If no recipe is prepared and thus no MVApp is loaded, the Frontend will show a respective text message.

MERLIC RTE Startup

When starting MERLIC RTE, the various components and settings will be validated and loaded:

• If any settings have been defined for MERLIC RTE in the respective INI configuration file, for example, port settings, they will be validated and used for the MERLIC RTE process. For more information, see Configuration Options for MERLIC RTE and Additional Settings for Communication Plug-ins.
• If a default recipe is defined, it is loaded. The MVApp that is referenced in the recipe is loaded with the configured parameter setup. If the recipe references an acquisition sequence, it will be automatically activated.
• If an instance of a communication plug-in was running in the last session while MERLIC RTE was stopped, MERLIC will try to start the plug-in instance again with the respective plug-in configuration.
• If MERLIC RTE is started via the MERLIC RTE Setup or the Windows start menu, the MERLIC Frontend is automatically opened. If no recipe is prepared and thus no MVApp is loaded, the Frontend will show a respective text message.
• A new log file is created for the MERLIC RTE process. For more information, see Logging.
