Hi

I have an S7-1200 CPU I download the program with desktop PC and monitor it and everything is fine, but whenever I use a laptop I can not connect to PLC, even I used another laptop and either this does not work. evey thing (I mean software) in the PC and laptops are same.

Does anybody know what's the sulotion?

Hello,

which messages you get if you try to connect?
Can you ping the PLC from the Laptops?

Regards

Christoph

thanks for reply

With laptop I can connect to S7-300 (CPU 315 2pn-dp) and s7-1500 and et200sp but I cannot connect to s7-1200.

In accessible nodes  It can find the nodes and but whenever I try to download it tells can not establish connection.

I use PNIE in the configuration to connect.

I also have a tp 1200 comfort that I can not download with PNIE but it works with ethernet but the PLC does not have this option to connect

i've tried all these ways.

Eventually I installed "SIMATIC STEP 7 Professional 2017 v5.6" and I could download TIA portal V13 SP1 project to PLC!!!!!!!!!!!

Maybe it's installed some drivers or corrected some bugs in TIA!!!!!
