Hello,

 In the last two weeks I am trying to to establish data exchange between two S7 station via IE. On first I have CP-343-1 Lean (CPU is 315DP v2.6) and on second is ET-200S (CPU is im-151-8 v.3.2) with integrated PN.  I have considered all option which I know. CP does not support support T-block, im-151 does not support support tcp in NetPro. CP cant use PUT-GET or other S7 connection. Apparently, there is no common options for both stations. What can I do. What possibility exists for this situation?

Hello milovjani;

In the following discussion, our friend fritz has provided some very important information that could be helpful in your project:

how to communicate between CPU315-2DP with CP 343-1 lean and IM151-8 PN/DP CPU

Hope this helps,

Hello,

addition to Daniel's post, if you decide use your CP343 Lean as Client, you can use it but with AG_CNTRL, AG_SEND and AG_RECV instructions (FC5,FC6,FC10). In this case you can create your connection in NetPro as active to server (other device if capable) and Exchange data. This system I was used previously with connection to PC application what was acted as Server. On ET200S side with integrated Profinet Port you have available instructions for CPU integrated PN port, look to Daniel's sugested post, documentation.

hi,

from CPU-CPU Communication with SIMATIC Controllers:

Communication is possible, but the S7-300 have to be server for the IM151-8, so the blocks have to be used in the IM151-8

As you can see, also the T-Blocks are possible. For this blocks you don´t need to establish a connection over NetPro. It is a programmed connection. TCON will establish the connection and TSEND and TRCV are for sending and receiving.

hope this helps,

regards,

Thanks for all suggestions, a will try tomorrow, again.

I already try PUT-GET and it didn't work. Probably I made some stupid error. I have copied block FB14 and FB154 from NET_CP Library, not from Standard because my IM-151-8 haven't SFB14 and SFB15 blocks. Is it OK? Of course in other things I followed guidelines from manuals and examples. In NetPro I used unspecified partner and got proper ID, but nothing good happened. I even copied station from 315 Project in my ET200S project and did merge of subnets, without results.

As regards T-blocs I have used Open Communication Wizard for creating required DB blocks, but changed my mind when I saw that there is no option for CP-343 in Interface, just for CP-443. Then I read one post from Fritz where he said that T-blocs is not option for CP-343. Did I use correct method for T-options?

I would be grateful for your suggestions in respects of my dilemmas mentioned above.

Thanks for explicit answer about source for FB blocks, Fritz.

My dilemma was consequence of error report when I first time download blocks for PUT/GET (from Standard Library). Something about missing declaration for PLC type and problem with calls for SFB 14 and 15. Then I saw in online monitoring of IM-151-8 there is no SFB 14 and 15 blocks. I used exactly same examples for making program as you linked in your answer. Of course, I created instance DB in my Project. In Help stated suggestion to check did I use supported blocks for chosen PLC.Then I tried with Net Library, errors was vanished, but without communication.

Unfortunately, automatic line with previous described S7 station today was in working regime and because that I was not able to experiment anything today.

I would appreciate if you have some advice or answer what is reason for appearing described errors about used SFB blocks. Is there something I can do about that, or I need to ignore them.

Thanks in advance!

hi milovjani,

have a look to the FAQ, fritz sent you, again. Everything is described there

How do you program communication blocks FB14 "GET" and FB15 "PUT" for data exchange in the S7 program of an S7-300 CPU?

Have a try, and delete everything you programmed before with this communication, and make it from the beginning. It works! I have done it many times.

There is also a sample-program, at the end of the FAQ. Maybe this helps.

regards,
