Signals and Commands

The configuration of the respective device that is used for the communication during the MERLIC 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. is mostly done in the MERLIC RTE Setup. To establish the communication between MERLIC and the device, you have to consider various information such as the available internal states of MERLIC during the process integration or the available signals and commands for the respective devices. This information is required to correctly configure the communication process for the process integration.

In case of Hilscher cards, the programmable logic controller (PLC) must be configured to use the correct commands and protocol, according to FromPLCProtocol for the data exchange. If the configuration is not set correctly, MERLIC or the industrial control system, e.g., the PLC, might not be able to process the transmitted data correctly.

If you are using the provided OPC UA server plug-in or want to implement your own plug-in using the MERLIC Communicator, please also refer the MERLIC Communicator manual and the reference documentation of the Communicator for more information about signals and commands.
