Can a PLC send data to an Arduino?
You only could send data between an IO-Link device and an IO-Link Master (your PLC). Your Arduino don’t have any IO-Link functionality (I guess), so you had to find another solution. Thanks for contributing an answer to Electrical Engineering Stack Exchange!
Are there any projects using Arduino as an IO-Link slave device?
I looked around but found no info about Arduino and IO-Link, are there any projects using Arduino as a IO-Link slave device? IO-Link is a communication protocol intended for industrial environments. It usually involves voltage levels of 24V.
How does PROFIBUS-DP communication between Arduino and plc?
In addition, we can extend Input and Output of PLC through Profibus – DP interface. It means that Arduino can works similar to Siemens DP/DP Coupler Module to connect two Profibus – DP networks together. And this DP/DP Coupler’s price is also very expensive. We can refer to their prices as follows: Communication Module CP343-1 Lean.
How to configure Arduino into Siemens PLC system?
Learn about *.GSD file to configure Arduino into Siemens PLC hardware system. The PROFIBUS DP network is based on an RS485 physical communication and it has to strictly follow the telegram format structure and telegram sequences defined by PROFIBUS network.
Arduino –> WaveShare RS232 shield –> Serial Cable –> PLC (The shield has it’s RX and TX pins connected to the Arduino pins 16 (TX2) and 17 (RX2), VCC and GND to 3v3 and GND) But in this setup, it isn’t working.
What kind of communication protocol does Arduino use?
IO-Link is a communication protocol intended for industrial environments. It usually involves voltage levels of 24V. Apart for that, you will have to write your own communication stack on the Arduino (as far as I know there is no open source stack, although the standard is an open standard).
