Zenon 5.50 Variables with surreal values.

Zenon 5.50 Variables with surreal values.

Hello,
We have Zenon 5.50 connect to Modicon tsx mirco by modbus.
The project is old but the enterprise is now more big than before. Consequently, Zenon must read more variables, but we have problems. Momentarily, the indicators take a surreal values. We have cuts in graph.
The department of quality doesn't accept the graphs. We have a lot of cuts.
The cuts isn't problem of Modicon. The ladder code of Modicon run fine. I write a code with ladder... ( If... %mw2102<2 then put on bit test) The bit test never change.
It happens with constant variables too.
Any ideas?
Thank you
Narc­s
