Hidesmul24, I have attached my network architecture here. when I run Wincc V7 RT in 2 servers(Redundant), both the servers are really quick in updating PLC values. Then if I activate runtime in any two clients, then also it is working fine. If I activate runtime in third client, the scada is taking 25sec to update tag values from PLC. Also the server (SERVER A) which the three clients are pointing to is slow but the standby server (SERVER B) is fast. If i make three clients point to SERVER B then SERVER B is slow and SERVER A is fast. we called siemens network expert and he told there is no problem in the network, the problem is at application level. Any clue where I have to look into. Regards, Govind.

Raja, iIt's hard to tell what is wrong, cause can be several things: scripts waiting for each other, update cycles used on your pictures,... Please check your log-files, usually under "C:\Program Files\Siemens\WinCC\diagnose"...especially the ones related to your communication(s). Check these logs for entries around the time that your problem(s) start. |

usually there are several log files in that folder? Check the one whose names is related to your communication channel, for example "SIMATIC_S7_PROTOCOL_SUITE_01.LOG" |
