Introduction to Modbus Modbus protocol is a master-slave communications Industrial architecture (RTU), created to be implemented Modicon PLCs. Why use this protocol and consider that it is better than other industrial protocols, implementation is easy and simple network configuration dropping down is defined (RTU) by way compact binary data concerning the device connection with a…

PLC Panasonic FPX C14 R
Serie FP-X I present the Panasonic FP-X (Nais -Aromat) series Controllers PLCs or Programmable Logic has evolved, this series the successor to the FP1 series with a small and larger memory size and speed processing value optimized for control systems motion has a varidade of cassettes Ethernet communication protocols RS232 – RS422 and RS485 has…
Modbus RTU Master tests with Arduino via RS232 and PLC Panasonic FPX C14R
This time I have communicated the Arduino with Panasonic PLC and I checked the Arduino useful in the industrial field direfencia of the previous tutorials I’ve tested both devices communicating via RS – 232. Summary 1. The arduino send via modbus ADC value 0 to Holding Register 0 and the plc into a strategy…
Modbus RTU Master tests with Arduino via RS232 and screen Panasonic GT01
On this occasion I made our arduino communication with HMI Panasonic GT01 monochrome display via RS232 Modbus RTU, Arduino screen as Master and slave. Summary 1 The value of the ADC 0 of arduino from a potentiometer 100 k will be displayed on the HMI Panasonic 2 The value entered from a keypad from…
Modbus RTU Master tests with Arduino via RS232 Part 2
In the previous test, performs the communication between Arduino Mega 2560 and a Modbus simulator slave THROUGH the USB port that commonly have our arduino, in this case we will test with an Arduino as Master Modbus but via RS-232 with our PC – simulator modbus slave. Arduino Communication Modbus RTU Master and Slave Simulator Architecture Materials …
Modbus RTU Master Library tests with Arduino Part 1
I start with the following question Arduino can be used in industrial aplicaiones? of course, using a common protocol used in the industry called Modbus Serial RTU in this case configured as Master. MODBUS communication is done by sending the value of A0 (ADC0) 10 modbus records using a potentiometer 100k variation is performed. …
