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 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.  …
