Cannot set variable tag to number higher than 100

Hello,

I have a strange behavior in CitectSCADA 7.40 and two variable tags! I cannot set them through SCADA to a value more than 100, it just ignores the new number entered, but if I set the number in the PLC, SCADA shows it properly! The variable tags are pointing to DT1219 and DT1235, which are normal working address, and are of INT types.

Any suggestions as to why a number higher than 100 is being ignored? There are other similar variables, of INT types, that works just fine, and are used the same way to modify their values.

Maybe the Eng full scale of that tag is 100

It was not, but I created this variable from a variable that had one! I deleted the Eng scale but seems SCADA kept it anyway. I tried to renter one and delete it, no change. I deleted the tag than started from one that had none to recreate the tag and this time it works!
Small bug in version 7.40 SP2! Thanks for the suggestion that helped find a resolution :)

Hi Hubert;
This is normal to Citect.
You cann't enter a number to a tag thatis higher then the "Eng full scale" .
However when reading from PLC, the tag will display the correct value even if it is higher from the "Eng full scale"

But there were no more Eng scale set in the variable! Citect was still considering it, so I had to delete the tag and recreate it from an entry I knew never had an Eng Scale set to it.

I think default is 0 to 100 Eng scale.
Always configure scaling for variable with data entry.

Maybe the change never got compiled. I always disable Incremental Compile (Project Editor | Tools menu | Options) so it does a full compile each time and eliminates problems like this where changes don't seem to take effect. The other option is leave incremental compile enabled, but compile 2 times in a row. It will say there are no changes to compile and if you choose to compile anyway it will do a full compile.
