In steel making plants there is various aspects of KPI and production parameters that is always monitored by the Engineers and managers during the day.
These data is already available on the automation system (PLCs, MMI and configuration data bases) but it is depressed during this different source.
The idea of the project is to collect all this data in a single dashboard for each area of the plant that display this data in a easy way to be monitored both during work hours and the rest of the day ( by using the plant VPN network).
So a dash board with developed with node-red running on a Raspberry Pi 3 B+ as the server.
The Raspberry Pi is connected to three different network (area 1 automation network, area 2 automation network and business network)
An additional wireless network card was used to connected to area 2 automation network while utilizing the built in Ethernet and wifi to connect the business network and area 1 automation network.
The connection to the area 1 & 2 automation networks was needed to collect data from the different PLCs and databases.
While to connection to the business network was used to connect to the dashboard for any computer of smart phone in the company network as well as through VPN from out the company premises.
Additional nodes was used in the node-red environment to facilitate connection to the simatic S7 plcs.
Additional nodes was used in the node-red environment to facilitate connection to the simatic S7 plcs.
Other devices was connected trough a socket connection and the data was parsed using a function node and some JavaScript code.
