Client Citect SCADA cannot connect to server

AO

Hi all

I tried to connect Citect SCADA Client to my Server.

The client hardware alaram shows "No IO Server Could Be found" same the thing for server Alarm and Report.

i find some document that say if you get "No IO Server Could Be found"  you should open ports (2082, 2083...) in the fire wall to connect client to the server. I tried to connect to IOServer Port 2082 Via Telnet but it dosent work.

When i usethis command on the server: Telnet 127.0.0.1 2082 its fine but when i change 127.0.0.1 by The server IP adresse 192.168.10.112 on the same machine its not working. i disabled the firewall but still not working. Then i made my local network private but still not working.

Can you plz help me

Thank you all

  • Hi Sir thank you for your reply
    Plz fin my answer below each question:
    1. After changing your network type, did you make sure to check again if the firewall was off for private networks?
    Yes it was Off
    2. Did you disable the firewall on both machines? yes i did
    3. After changing firewall settings, have you rebooted the machine? Normally not needed, but you never know...
    No i didnt i thought its not necessary
    3. Can you ping from both machines to each other?
    Yes i can ping both sides
    4. Are there any other firewall devices in your network (switches, routers etc.)?
    No just a regular unmanaged switch
    5. Do you have anti-virus or anti-malware software enabled that can block or filter network traffic?
    yes i have anti-virus Trend Micro Security but it was Off.
    There is no way to try to know wich application is blocking those ports?
    By the way im using windows 10

    When you get it working eventually, please try to re-enable everything you turned off, step-by-step. Better to add the ports that need to be open to your firewall exception rules, than disabling the firewall altogether.
    yes i will do it step by step thank you for you advice
