  • How Web Server on PHPoC Works

    PHPoC devices have an embedded web server. It enables to control, monitor or do setting via web browser.

    Now, Let's see how it works.

    After developing source code files and upload it to PHPoC devices, you can access it via web browser.

    When you types IP address of PHPoC on web browser, web browser actually makes an HTTP request to PHPoC device.

    When receiving HTTP request from web browser, Web server does:
    • Get the requested file name on PHPoC request. For example, if you type "http://192.168.0.180/my_file.php", the file name is my_file.php. If you do not specify file name (just type "http://192.168.0.180"), the index.php file name is used as default.
    • Finds the file in system.
    • Reads that file if the file exists.
    • Seeks for PHPoC code in the file (PHPoC code is placed in side "<?php ?>" or "<? ?>" tags).
    • Interpret PHPoC code. (PHPoC code can be used to monitor/control sensors/devices or other works)
    • Send the interpreted file to web browser.
    The interpreted file is client-side code, which includes HTML, CSS, and/or JavaScript.

    Web browser displays web page according to content of the received file.

    • Arduino - RS-485 Expansion Board
      by support
      PES-2607 is an easy-to-use RS422/RS485 Expansion Board for Arduino Uno and Mega, which allows Arduino to exchange data with serial device via RS422 or RS485.
      Especially, Arduino does NOT use UART pins to communicate with RS422/RS485 expansion board. Therefore, users can use Arduino UART pins for other purposes.
      Moreover, A single Arduino Uno/Mega can communicate with multiple RS422/RS485 expansion boards (up to 14) without using Arduino UART pins.
