The WT32-ETH01 module is an Ethernet adapter that integrates the ESP32 microcontroller with an Ethernet interface, allowing for wired connectivity in projects that typically rely on Wi-Fi or Bluetooth. It’s popular for applications requiring reliable communication, low latency, and stable networking in local environments or embedded systems. WT32-ETH01 Functionalities WT32-ETH01 Specifications Components and Integrated Parts…
In this opportunity we will carry out tests and explanation of the Modbus RTU protocol implemented in ESP32 requesting data from the Single-phase consumption meter PZEM-016. The intent of this tutorial is: 1. Explain in a simple way the creation and operation of an industrial protocol, in this case the Modbus RTU protocol used and…
Originally this test is performed in June 2018 in less than one year, for reasons of availability do not publish, technically just missing the documentation, then I will present the results, well they say there is better late than never. In this opportunity our PZEM-004 meter or it is also possible with our PZEM-004T communication…
In previous tutorials, we conducted tests with the PZEM-004 y PZEM-004T with display, single-phase power consumption meters , which have great potential for basic applications of electrical consumption measurement or active power. For some months I have a new Peacefair PZEM-016 meter which has features and additional improvements which we will see in the following…
We have performed several tests regarding Arduino integrating Arduino-PLC and Arduino-HMI Panasonic for Industrial applications, in this opportunity we have found other libraries for Arduino as Master Modbus RTU, which we will use only in Modules ESP8266, main advantages of the library has Easier facility regarding read and write log settings. Initially the libraries only…
This time we will test the Groov platform, but what is groov? Is a solution (IIoT) created by Opto22 for the visualization, control and monitoring of industrial equipment from pc, mobile devices, tablets, smartphones and smart tv. It supports SNAP PAC controllers, Modbus TCP / IP devices and other PLC controllers from other brands such…
For this test Users of a Panasonic FPX C14R PLC that have communication via serial RS232 and its protocol is Mewtocol, an ESP8266 01 module configured to function as an Ethernet Serial bridge has been integrated, of course adding a MAX232 chip that performs TTL conversion to RS 232. The result of this test is…
In the search for attachable communication protocols Node-Red I found thanks to the collaborative development a library or nodes for communication Modbus TCP IP, the following tutorial is indicated as installing the nodes in lubuntu (Ubuntu). Previous tutorials Recommended Tutorial 1 : Install Lubuntu (Ubuntu) Tutorial 2 : Installation node red platform Tutorial 3 : Installation…
There have been numerous applications in the ESP8266, I have taken as a goal to integrate this module into one of the industrial protocols most commonly used Modbus TCP IP, it would be good to have a node or sensor that sends data or a driver, OPC, PAC, PLC, HMI or SCADA. A long time…
The Panasonic PLC in this case the FP-x Family has embedded Modbus protocol, setting the test be conducted Panasonic PLC Modbus RTU Slave. Serial RS485 Modbus RTU network We will communicate with a Modbus simulator right through RS232. Documentation for panasonic in the family FPX there is a routing table registers between native Modbus…
