The first is the docking of equipment in the industrial field, the so-called OT network. In the traditional OT network, PLC acts as a logical controller to monitor and control the status of executing equipments on site to ensure the coordinated and orderly operation, various sensors collect data and feedback, and HMI/SCADA system monitors the running status of the whole factory.
Since each automation equipment manufacturer carries out different communication protocol standards, the industrial communication network composed by core PLC may also adopt different communication protocols. The complexity of communication protocols is the first important challenge for the Industrial Internet of Things.
The second part is data sharing, that is connecting to IT network. IT engineers are likely to be more familiar with technologies such as databases, high-level language programming, network communications... This is quite different from the technology involved in OT networks.
On the premise that the Industrial Internet of Things can be compatible with OT network, can also use various IT technologies for data docking. Therefore, for the Industrial Internet of Things, in order to achieve better interconnection, the integration of IT and OT is a process that must be experienced.
What we really need is to explore the value behind the data, which involves the necessary processing of the original data. Of course, we can send the raw data directly to the cloud/server for data processing, but this often leads to efficiency issues and network bandwidth pressures. A better approach would be to process the raw data collected directly at the edge.
First of all, EG410 and EG500 inherit the advantages from Raspbian OS, which means over 35,000 software packages or pre-compiled software comes from Raspbian can be used directly on Elastel IoT Gateways, and users can configure and secondary develop on it with a high degree of freedom.
In addition, raspberry PI's active community support is also a great engine to Elastel IoT Gateway. From basic high-level programming language support (such as Python, Java, C, C++, etc.), to pre-installed Node-Red environments, enhanced the Elastel IoT Gateways a wide range of possibilities.
* Using CODESYS on EG410 and EG500 may requires the additional licenses purchase.
