SQL Data Corruption

Recommended Posts

Hi,

I need help to tackle a problem,

Cyclic i write data into an table, this works like a charm. However at random events there is some kind of data corruption.  All 4 columns are written with a large number. 

When i Look into the PLC the data is 100% correct.  Making a SQL trace data is  incomming wrong, please refer at the attachement

This is just in one of the 1000 times.

Changing the write interval does not help. 

We use CAT6 shieleded  cable. 

Thanks in advance!
