INTRODUCTION

PLC Controller Communication API via TCP Protocol
This section provides an overview of the API designed for communication between a PLC controllers and a local server using the TCP protocol. The local server can be a standalone computer or a virtual server that acts as an intermediary (Broker). Once the data is received by the local server, it is further transmitted via HTTPS to the main DLB (Data Logistics Server) service. This setup ensures secure and efficient data exchange, enabling seamless integration between industrial automation systems and centralized data management platforms. The API is designed to be robust, scalable, and easy to implement, supporting real-time communication and reliable data transfer.

Requirements

To install requirements, enter the following commands at the terminal prompt 

sudo apt update
sudo apt install apache2
sudo apt install php
sudo apt install curl
sudo apt install php8-curl

Next paste the DLB script into a file /var/www/html/index.php

On the end pleas remove the file /var/www/html/index.html

Warning: The local server must never be exposed with an external IP address. Doing so will make it vulnerable to hacker attacks, potentially leading to unauthorized access and the blocking of the local server.
