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

Is it something to do with the DCOM settings ..
I'm not sure, just guessing..

Hi Galli,

Where I can adjust the settings for DCOM? What could be the worst possible effect when I adjust it wrong? Thank you Galli.

Warm regards,
Rey

I'm not the expert..
But if you to see/check the DCOM as this example will do...

Hi Galli,
I don't config the dcom as because i don't know what will be the effect after configuring it.
Could anybody have some more idea on this?

Warm regards,
Rey

Hi Galli,

I found it, the cause of the tricks is my panda antivirus.

Thank you very much for all of the helps.
