Hello, my name is Lucian, I am new to arduino, I'm trying to connect the Arduino via Modbus with a rockwell plc, would help a lot if someone had some sample code for modification.
I am wanting to use the Arduino and interface with plc Rockwell (Micrologix 1400) as the main driver.
Thanked already.
would help a lot if someone had some sample code for modification.
All you needed to do was ask.
void setup()
{
}
void loop()
{
}
Hope that helps. Good luck.
ya SURE.tELL US ABOUT setup and also paste your code
Actually not even know where to start , create the logic to receive commands via Modbus in micrologix is a little easier for me than writing code from start to send commands to arduino micrologix . Appreciate it if someone had some sample code or a sample code to send ASCII data to ASCII micrologix.Eu can export the data as follows micrologix these data by the open notepad . The extension of the file is EAS .

Hi Lucian,
Start with Google Code Archive - Long-term storage for Google Code Project Hosting.. One of a few modbus libraries for arduino. It is pretty stable as I have tested it with many commercial, industrial and marine equipment.
