Hi everyone.

I need help with configuration connection PLC <-> PC server. I use CPU 1511. Server has specific IP adress and Port number, delimiter . Which kind of connection choice ? TCP connection ? From server I must get data ( string, index ). To server I must set data ( string, index ). Did anyone done something like ? Maybe is somewhere an example how to do ?

So, do you have to use TCP or not? Lets clear that out, before starting to solve the problem.

So, I'd say that you want to use Ethernet TCP. I also presume that you want to communicate with PC (you didn't give other PLC), you sould try to do it using PUT/GET functions, or T-blocks. PUT/GET may be found in S7 communication library, and T-blocks in Open User communication. As you are using CPU 1500 series, regarding T-blocks, you can use TSEND_C and TRCV_C... link.

Thanks for answer.
Maybe You know what kind of server I can used for test ?

According specification I must get data ( like a string with the corresponding index ), and the same data I must send to another server.

HI,

here is the thing. There is no actual server... Communication between two partners (in your case PLC and PC) does not require any particular server (hardware). It's just the meter of specifying who is the server and who is the client between two of them. (in your case PLC would be server and PC would be client). See the: link.

Hello

I learned a little more. I was talking about a program that emulates server and I found a server project on VB. But in these case I send data to PC. It's second point in my project.

Now I want read something from server, eg data record with  index specyfication.
