PLCLink vs MQTT Manager

Supervision application for PLC or other URL command device. Particularly intended for supervision integrators, for research laboratory, up to end user or home remote. PLCLink can read and write one or more accessible PLC over Internet with ModBus or HTTP protocols and is well adapted for numerical results presentation. You just add a XML file inside app documents folder or inside PLC folder, some web page help you for this work. Transfert between PLC and application with ModBus (502) or HTTP (80) format. WAGO PLC are full compatibles because of SSI capabilities but some other ModBus PLC can be used to. • Configuration are easy to send for end user with a email. • Cell value can be send by email. (IFTTT action). • A room can be protected with a PIN code. • DropBox can help you for file storage. • QR Code can load wagoML source with plclink:// protocol. • Data can be saved in a .csv file. • Modbus record transfert mode for easy debug. • Modbus can now be synchronous for Schneider PLC. • Many data representation : text, days, month, bits and explicit icon. • A colorPicker for setting RGB lamp. • Push notification. • Action with javascript objects into iFrame. IPad version is very powerful with self editor for wagoML local file. PLCLink questions regularly this file (2s) and display results in a specific room window. This file comes with WagiML format, you will find a description here : http://pautex.fr/plclink/wagoml.php Entries can be saved and email up to final destination client, very easy to managed. This version allows playback of information by a url, the answer is direct text reply or included in an xml or JSON structure. These mode are ready good for small device as MBED and Raspberry PI. PUSH notification You choose a random 10+ digits number and simply with reading a specific URL you send calls to iPhones recorded with this number. All PLCs connected to the Internet are capable of producing this notification. Development : Pautex JF ¢ Pautex 2011-2024, NANCY

MQTT Manager is a general-purpose application to read and write topics on a MQTT broker through a friendly interface based on widgets. The application is organized in 4 tabs and each tab can contain any number of widgets. Widgets are chosen between the available ones: * Display: Shows a numeric value or text (scrolling it) * Gauge: Shows a numeric value over a graded scale * LED: Shows the value of a topic as a LED on or off * Graph: Shows the values of a topic as a graph * Switch: Writes a value to the topic depending on the switch position * Secure Switch: Similar to the Switch Widget. To operate the switch, the protection has to be remove with a click on the yellow bands though * Switch & LED: Writes a value to a topic and shows its value as a LED on or off * Knob: Writes a value to a topic proportional to the position of the knob * Slider: Writes a value to a topic proportional to the position of the slider * Push Button: Writes a value to a topic when the button is pushed and another value when it is released * Text: Writes the value entered by the user to a topic The application includes: * a complete user manual * documentation to learn the MQTT basics * the documentation to install a private MQTT broker on: * Raspberry Pi * Linux * macOS * documentation to use the Adafruit IO service instead of your MQTT broker. This allows to get started in a few minutes, without installing additional software * documentation includes how to configure a local mosquitto broker with authentication, using SSL and using client certificates for users/devices identification and authentication * Arduino ESP32, Arduino MEGA, Arduino Nano 33 IoT and MKR1000 sketches to create a MQTT node which sends data to the application and can be controlled by it * Raspberry Pi Pico W micropython script to create a MQTT node which sends data to the application and can be controlled by it
