Communication between PLC and Raspberry PI

[SternTech]

Hello, I was wondering if it is possible, for example, a PLC control for Raspberry PI, or read values ​​of PLC with Raspberry PI.

Thank you !!

Not sure if this will help, but a lot was discussed on this subject last week, follow the link.

Hello Badger, I was not very useful but thanks anyway !!!

There are quite a few open source libraries to communicate using Modbus. You might look into pymodbus or jamod, depending on your programming language preference.

EtherNet/IP works too on the pi, if you have a Rockwell, Schneider, or Omron PLC.

Hi robertkjonesjr

I want to make the Raspberry PI send data to a PLC Siemens S7-1200 would be possible with Modbus or Ethernet/IP??

Thank You!!

 

[robertkjonesjr]

I'm not a Siemens guy so do not know if they support ModbusTCP directly or not. I am sure their will be gateways that can do it.

This link is a start -for OpenModbus.

search for kurt braun on youtube.
and yes it is good possible with the libs from www.oscat.de
(can be used on siemens and on RPi

Hi

You could try Snap 7 from Sourforge

Stuck! Please help me

Hello guys. I am trying too establish a secure connection between my Schneider plc and my raspberry pi. What i want is my pi to read the values from plc and then transmit those values to cloud. Any idea how this can be done?

 

[boneless]

I think NODERED should be able to handle that. Do you have MODBUS available on the Schneider PLC?

Alternatively, check out CODESYS for RasPi

 

[Epy]

Node-RED would work for that as boneless said. Make your PLC a Modbus TCP slave, RPi will poll it and send to cloud in whatever shape or form you want.

Hi!

An alternative to your RPi would be IOT2000. There is a lot of information about it here:
