INISA develops a communication software for Omron PLCs network, capable of using FINS protocol, the most common in these PLCs. The program, developed on platform VBnet, runs on a Fanless PC, without a monitor or keyboard (Does as a data logger) and allows the capture of data from various processes of various PLCs, managed by their occurrence events.

To create a digital platform (Web Server) that provides a personalized solution to companies and thus have the information thy consider relevant to their processes, accessible at any time, from any place and device ( Anytime / Anywhere / Any Device Concept), segmented for each category of factory staff that should received and analyse it.

Our customer, Capital Goods manufacturer, and in a line that is already installed and in production, wants to register and analyse information relative to energetic consumption, reached pieces production and other plant parameters, that allow future decisions for the optimal exploitation. Both, from the point of view of the line manufacturer (Hours of use of the different sub machines, spare parts management, load percentage respect to the nominal, etc.) as well as the point of view of the production/productivity achieved. All this in order to optimize and offer better installations and services to its customers in the future.

MQTT (Message Queue Telemetry Transport) is a lightweight Machine to Machine (M2M) communication protocol that is used in Industry 4.0 and IoT applications environments. It is an open standard (ISO / IEC PRF 20922) and it is based on the publication-subscription pattern. It works on the top of the TCP/IP stack. Its main objective is to exchange messages between clients and a server (Agent-Broker). Clients can decide for themselves if a message is important to them, depending on the topics to which they have subscribed.

What is needed is to identify the necessary and existing production variables in the plcs already in the plant to be able to access to its variables bidirectionally (reading and writing) using a browser, interacting in this way with their information from higher-level systems.

Fusion furnaces, refining furnaces, continuous casting, refrigeration … processes All of them associated with the castings done in a steel mill and which have to be registered in real time on a Common Data Base for the access from any computer of the plant or from outside…
