This this file, Modbus TCP based machine connectivity has been handled. Additionally, data has been pre-processed using Connectware Rules.
The example below uses an additional Docker image provided by Cybus that requires a suitable license. You can check the current capabilities and permissions of your Connectware license in the Cybus Portal (https://portal.cybus.io ). If your license is not eligible to use the example Docker image, please contact Cybus Sales (sales@cybus.io ).
