PLCSim Netzwerkerweiterung "NetToPLCSim"

[Thomas_v2.1]

Hi,
your WinCC PC has 192.168.1.1 and your Step7 PC has 192.168.1.2? Then the IP addresses should be correct, and nettoplcsim/plcsim is reachable at IP 192.168.1.2.

You could try to start the monitoring in nettoplcsim and see if there are any connection requests. You can start it with right-click on the station you want to monitor in nettoplcsim (see attached screenshot).

If you don't need the multiple instances option, you could test with the older 0.7.2 version. Under some circumstances the new version has got some problems with WinCC.

Hi

thanks for your attention

yes, my WinCC PC has 192.168.1.1 and your Step7 PC has 192.168.1.2

I use monitor before but nothing happen
there isnt any request connection in monitor window

I also test with nettoplcsim V0.7 but It also cant be successful

I strongly need help

Which operating system are you using? Nettoplcsim runs only under 32-bit Windows.

If you have any firewall software running on your Step 7 PC, you have to permit port 102 for incoming connections.

I use xp 32 bit

even i turn firewall off
and also i check 102 port by Tcpview software
and just nettoplcsim is use that port

[saman4389]

in nettoplcsim v0.7.2 I use cpu with cp 343, is it correct?

my wincc lisens was expired, dows it important for disconnected connection ?

Maybe.
You can try the libnodave test programms. I attached the necessary files (libnodave.dll and testISO_TCP.exe), but you can download them also from libnodave page at sourceforge.
Unpack the files on your WinCC (or any other) machine, open a command line and navigate into the folder.
Then try

testISO_TCP.exe 192.168.1.2

The program connects to the plc with IP 192.168.1.2 and tries to read some variables from DB1 and 16 Bytes from marker 0 to 16.

thanks Thomas

what does libnodave show me ?
i load very small program too plc, it is just a start/stop circuit (with address Q0.0 )

It's a little test-program that does nearly the same as when you start WinCC with configured variables with addresses MD0, MD4 and MD8.

If the testprogram is able to read out the variables from nettoplcsim, then the setup of plcsim/nettoplcsim and your network is OK. Then the problem is your missing WinCC license.
If you have no program loaded into plcsim, it should show an error when reading variables from DB1 (because not available) and show the values of zero for the marker-words.
Your output seems like this:

E:\libnodave-0.8.4.6\win>testISO_TCP.exe 192.168.1.10
openSocketw.c: Connected to host: 192.168.1.10
Connected.
Trying to read 64 bytes (16 dwords) from data block 1.
