Decentralized industrial plants, such as sewage treatment plants, waterworks or district heating plants, have industrial control systems. However, they are not constantly manned by operators and also do not have extensive local control systems. This makes the decentralized plant an automation island to begin with. For operating actions, maintenance interventions or even malfunctions, a visit to the plant by an operator is actually necessary. The solution that has become established for this is telecontrol technology. Good networking and reliable remote control software enables convenient operation and monitoring from a distance.
The Ewon Flexy 205 Remote Maintenance Routers go a step further here. In addition to pure remote networking for remote maintenance and remote control, they also connect the decentralized systems to a globally available cloud, the Talk2M-Cloud. This cloud combines the connected systems of a customer account into a holistically managed system inventory, enables remote access and provides up-to-date system data.
The Talk2M cloud offers a modern REST interface for other systems (What is REST?). Via this interface it is possible to integrate the entire system inventory into other system landscapes (e.g. ERP, MES, AI, BigData, Analytics, etc.).
With OPC Router we show here how data can be exchanged with the Talk2M cloud via REST. Please read the step-by-step instructions for the procedures below:
Prerequisite for the instructions is a configured EWON Flexy 205 connected to HMS’ own Talk2M cloud (you will need the tools eBuddy and eCatcher).
