Delay in connection reestablish for S7 driver

Post by deepaktony »

Hi...!!!

I am using WinCC OA 3.14 with S7 driver. When connection between PLC & WinCC OA breaks, it takes approx. 5 to 10 seconds to detect connection break and again connect the cable of PLC, it will takes approx. 30 seconds to establish the connection again.

Any one please help to reduce these time by change in any settings.

Hello,

with the following config-entry you are able to modifiy the time for alive checks:

[s7]
AliveInterval = 10 #default is 30 sec


The connection timeout (default 5000 msec) can be modified at the S7-Configurationpanel of the WinCCOA-Systemmanagement.

best regards
Rainer Glocknitzer
