I have a peculiar problem.
I am communicating with 5 PLCs using Modbus on TCP. I am using Ignition version 7.5.6 on Linux.
When i start my server machine, Ignition server also starts. The status window shows that it is connected to all the 5PLCs.
But when i view the tags, it shows bad quality periodically. (the value is there for 5 seconds then the quality goes bad for 2 seconds and then the value comes back. )This happens continuously.
But when i disconnect and reconnect the Devices(PLCs), this problem disappears…
That means every time i start my system, I’ll have to disconnect and reconnect all my devices, which is cumbersome and am sure something can be done to set this right… …
Looking forward to a solution.
