PROJECT DESCRIPTION

Welcome to a Siemens S7-1200 to Arduino Modbus TCP/IP Communications Tutorial 

 In this video we have introduced an Arduino into the mix, which communicates with the Siemens S7-1200 PLC and Factory I/O using the Modbus TCP/IP Protocol.

This Siemens S7-1200 Modbus TCP/IP Video is 1 of 3 Modbus videos where we deal with the Arduino; programming it to function as a Modbus Server. The Arduino reads a potentiometers’ rotational position via an analogue input then stores that value in an input register.

 In the following videos, the Siemens S7-1200 PLC, being on the same local area network is able to read the value stored in the Arduino Input register and use it as a setpoint to control the Water Level in the Tank.

 

As a prelude to this video you may want to watch the previous two videos on Water Tank Level Control as they will definitely help you understand what we are trying to achieve. The Links are below

 Siemens S7-1200 Water Tank Level Control Part 1. https://youtu.be/-hEjh5SEbrc

 Siemens S7-1200 Water Tank Level Control Part 2. https://youtu.be/poi08Wtxkbo To view the next video in the series, Siemens S7-1200 Modbus TCP/IP Communications with Arduino Part 3. select the link: https://youtu.be/OuSlJl8EHz0 A free 30 day Licence of Factory I/O If you would like to get a free 30 day licence of Factory I/O or even purchase a copy, you can use the link below. I will earn a small commission for this, however, it helps me produce videos like this one to help you program PLCs now and in the future and it shouldn't make a difference to the price you pay. Many thanks. https://factoryio.com/url-action?ref=... Details about my patreon account will be added here shortly.
