Dear All,

I' d like some help since I'm beginner in this. I have the following modules:

-CPU 313C order number: 6ES7 313-5BG04-0AB0 v3.3

-CP 343-1 Lean order number: 6GK7 343-1CX10-0XE0 v3.0

I want to establish an Ethernet connection so as to receive and send data from my PC. I use the following software:

-Simatic manager STEP 7 v5.5+SP3

-National Instruments OPC server 2012

-NI Labview 2014

I tried to establish an unspecified S7 connection but i failed. I'd like some ideas.

 Dear Nikosant,

I 've been in your situation and I had many of your questions when I started few months ago. Therefore my expirence may help you.

1- One very important point in order to make the LabVIEW application work is that you should have next 3 software packages installed in your computer (you can chek then in the NI License Manager):

a - LabVIEW 2012

b- Real-Time Module 2012

c- NI OPC Server 2012

Note that all of them HAVE TO BE the same version, 2012 or 2013 or 2014. As you have it now (LabVIEW 2014 and OPC 2012) will not work!!!!

2- Those are the steps to set the communication between the NI OPC and the PLC http://www.ni.com/tutorial/7450/en/ .As I said before, If you dont have the same version in NI software packages you will not get the option of "adding a new I/O Server" in your LabVIEW project.

3- Forget the S7 Connection (I spent a lot of time trying to make it work and it didn't :( )and go better for a TCP/IP Ethernet connection as described in attached document. It's easy and works. Sorry that it is not in English but I'm sure it will help you

4- I'm not 100% sure but I think that you will also need a NI DSC license, to run your application. Please check it. See this link "You need the DSC Module to use the OPC UA VIs on Windows targets, and you need the Real-Time Module to use the OPC UA VIs on LabVIEW Real-Time targets. "

For my application I used LabVIEW (RT and OPC)2013 and the S7 1212 PLC and it works :D I also tried with the Siemens Lean OPC and LabVIEW 2014 and it works as well. The only thing with this second option is that I couldn't make it work with the S7 connection so at the end I used the OPC UA from Siemens OPC Lean. 

Good luck!

Dear Nais,

I managed to communicate my devices last month and it's as you said. I used:

-Labview 2014

-DSC Module 2014

-NI OPC server 2014

and the TCP/IP Ethernet connection

Thank you
