Use some wires from Arduino to PLC.

Ciao, Ale.

Welcome to the forum.

Please read the first post in any forum entitled how to use this forum.,148850.0.html

  • What model Arduino and what model PLC.

  • What is your application?

  • What do you want to communicate between the two?

  • Simple slow digital ON/OFF?

  • High Speed comms (RS232)?

  • Analog Levels?

It is possible for Arduino to connect to PLC, but doing what is the question.

Thanks.. Tom... :slight_smile:
