Modbus RTU Master tests with Arduino via RS232 Part 2

Posted on by PDAControl

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

Posted on by PDAControl

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.  …
