Basic Modbus RTU Master RS485 Test with ESP32 + XY-K485 + PZEM-016 (without libraries)

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…

Meter PZEM-004 + Arduino Nano Modbus RTU (RS232) & Platform IoT Node-RED

Originally this test is performed in June 2018 in less than one year, for reasons of availability do not publish, technically just missing the documentation, then I will present the results, well they say there is better late than never.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…

Initial Review Meter PZEM-016 Modbus RTU RS485 by PeaceFair

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…

Tutorial ESP8266 12E Modbus RTU Master (Improved)

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…

Testing Industrial Platform Groov and ESP8266 NodeMCU

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…

Installation node Modbus TCP Node Red

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…

Update ESP8266 Industrial Modbus TCP IP V2.0

 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…

Industrial – PLC FPX C14R Panasonic – Slave Modbus RTU RS232

  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…

Introduction to OPC Servers

The OPC (OLE for Process Control) is a communication standard in the field of control and monitoring of industrial processes, based on Microsoft technology, which provides a common interface for communication that allows individual software components to interact and share data. The OPC communication is done through a client-server architecture. The OPC server is the…
