Does anyone knows this message in trace.log.
I can't find any rational explanation in the customer project.
This message appears directly in the PcVue start up
Thank you

Hi Manu,
I am not sure if it is related, just wondering if there could be any expression that is invalid from EXPRV.DAT and EXPRM.DAT.
Thanks,

Hi,
The trace file indactes that it is linked to OPC communication. Try to have to the configuration of the variables.

Hi Manu,
Just copy the following lines (Varexp.dat) in a blank project and you will get the error.
(It is a simple OPC loopback to retrieve @System.Station_number)
OPCDEF,LoopBack,"","SV.OPCDAServer.1",1,1,1,,10000,60000,0,,8,0,0,"",30000,300000,1,1,1,1

I will give the reason why in a second post.

Here is the explanation:
It should be "" instead of 0 for field OPC_CustomizationExpression
