Modbus

Modbus protocol is widely used in manufacturing environment such as automative industry, energy conversion plants, machinery networks and other industrial environments. Data generated within production zones, are now becoming more and more relevant for the business process management and optimization. Although modbus protocols is relatively old, it is still the de-facto protocol to share data within production related environments, thanks to evolved structure of the protocol with TCP support. Supervisory Control and Data Acquisition, shortly SCADA systems, are using information from different data generation, to mostly control the production processes. Evolving business flows requires information from every aspect of production tools. This data then used to analyse the efficiency, quality and performance of overall processes as part of lifecycle managements. This is why it is crucially important to transfer the data from production environment for further analysis, while keeping the machinery network isolated from any incoming threats.
