Hello,
I am trying to estabilish ISO-on-TCP connection between S71200 CPU 1214DC/DC/Rly and S7200 with CP 243-1 (6GK7243-1EX01-0XE0) but without  success (com_error.jpg).

In my case, S71200 is a client, S7200 is a server

I am using TCON on S71200 to connect with ETH0_CTRL on S7200.
S71200 com param (client) -> IP 192.168.0.1, TSAP E0.01 (tia_tcon_param.jpg)
S7200 com param (server) -> IP 192.168.0.2, TSAP 10.00 (wizzard.jpg)
In ethernet wizzard on S7200 i read connected module in wizzard so there is no way that i have wrong  slot, module number or something like this. 

Strange thing is, that when im trying to download project to S7200 i get warning (download_warning.jpg) that i have configured different module from these connected. As i said before, i read it in wizzard and double check catalog number.

What am I missing?

i attached also projects in .zip

Hello,

have looked to your files. Pls try for first start Microwin and go to PLC->Information. Check there if it all is ok, mean also realy type of that Ethernet module, or simply error messages. make Picture of that screen pls, post. PLC can be at STOP.

S7200 is not in stop mode i can tell You that for sure. On monday i will post screen of S7200 diag buffor if that can help.

In comm params is everything allright?

Hello,

I think ok, but thinking now about that remote TSAP (S7-1200) in S7-200 cfg. Maybe you can use simply 10.0 for that remote parameter (unspecified), but this yoy can test. Are you sure about that s7-200 HW cfg? I know that you said Yes, but that message point to that, have you only CPU224 and then only Ethernet module, or is some module putted between them? Via this answer you can check that S7-200 TSAP also. Really, now I don't be sure about S7-1200 TSAP ident 0xE0, max. can be 0xFD? With that STOP I meaned that is enough for me screen of CPU in stop, if it must be putted to STOP to make screenshot, nothing more. Ok, connect to S7-200 and make printscreen of that Information screen. Simply checking text of cover about type of module isn't enough for me sry, therefore that Info Online screen is needed. Cover is cover and can be anything.

If they are right, thing that im tyring to do is impossible. S7200 dont support T-Communication so i wont be able to exhange date using TCON, TSEND, TRCV functions

Hello,

hmmm but if you're right, simply think what kind of communication you can prepare with that full IEEE 802.3 standard Ethernet module??? Only S7 communication? I'm really doubt for that, because if it's like you mean that module is simply unusable. Simply that Ethernet module must working with ISO and TCP/IP. Nevermind pls go to MicroWin, start again Ethernet wizard and read first window about Ethernet wizard carefuly. What are there infos? Pls check this and give info.

Update: sry but I don't have any Ethernet module to check this, else I will be preparing my solution to check this. Look pls to Ethernet module documentation also.

Update from manual: Client/Server - PUT/GET, Server - READ/WRITE.

Update: http://w3.siemens.com/mcms/industrial-communication/en/ie/system-interfacing/simatic-s7-sinumerik-o/s7-200/pages/cp243-1.aspx

What can be answer?

Case solved.

I manage to get communication done with GET function. I attached some screens of TIA project configuration. TSAP adress of S7200 is clear (module number 0, connection number 0), but S71200 is a mystery for me. Every manuals that i find, including these in help were useless, because i get com when I randomly selected adress from drop down list, in my case 3A.01 (?). I tested it also with 10.01 (like on screens) but it didnt work, mayby because S7200 has 10.00? I dont know.

 S7200 is easier to configure using ethernet wizard. Just fill form with IP and TSAP used in TIA project and configure it as server, function ETH_CTRL block has to be called with every plc loop (SM0.0)

Hello,

great, but look, therefore I ask you for that Information screen of Microwin, there you can see module positions and simply check/count TSAP number.
