Hello,
Good day, I have problem communicating my Laptop to S7300 CP 343-1.
I can only monitor once but after I terminate it I cannot monitor it again, after that I tried to ping the IP adress of the CP and still I get replies but still cannot monitor.
When I close the program and open it again same things happen I can monitor it only once again.
I know best people to ask are here, please help me Friends. Thank you very much.
Warm regards,
Rey

Hi PLC_ITA,
Good evening, I already tried to turn off windows firewall of my computer but still it connect only once.
I'm now thinking of the port to be added on allowed on firewall because I have read something that even the firewall is off some of the ports are still close, i'm afraid that the port assigned to S7 is close.
How can I check the ports assigned to s7? Some more idea please,.
By the way Im using XP SP2.
Thank you very much PLC_ITA....
Warm regards,
Rey
