RSView32 VBA Excel

[Marie1982]

Hi,

I have 2 problems.

1- I have an RSView32 application which contains a memory tag defined with these parameters:

Min: 0
Max: 2
Scale: 0.01
Offset: 0
Data type: Default

On my display I have a numeric input with these parameters:

Field lenght: 20
Decimal places: 7
Format: floating point
Overflow: show exponent

In runtime, if I try to enter 0.5 i get the error "Attempted to download invalid floating point number '0.5', index 1"

Why and how do I correct this?

Problem #2

I use a bunch of tags defined in the same way than those en problem #1 to put in a Excel report via VBA code. I also get system values to know the time and date. Finally I also have a digital tag.

Here is how I get the values from RSView in my VBA code:

Dim tag(14) As tag

Set tag(0) = gTagDb.GetTag(sPoste & "\Rapport" & "\Chlore")
Set tag(1) = gTagDb.GetTag(sPoste & "\Rapport" & "\Debit")
Set tag(2) = gTagDb.GetTag(sPoste & "\Rapport" & "\Volume")
Set tag(3) = gTagDb.GetTag(sPoste & "\Rapport" & "\Turbidite1")
Set tag(4) = gTagDb.GetTag(sPoste & "\Rapport" & "\Turbidite2")
Set tag(5) = gTagDb.GetTag(sPoste & "\Rapport" & "\Turbidite3")
Set tag(6) = gTagDb.GetTag(sPoste & "\Rapport" & "\Turbidite4")
Set tag(7) = gTagDb.GetTag(sPoste & "\Rapport" & "\Filtre")
Set tag(8) = gTagDb.GetTag(sPoste & "\Rapport" & "\pH")
Set tag(9) = gTagDb.GetTag(sPoste & "\Rapport" & "\Temperature")
Set tag(10) = gTagDb.GetTag("system\Month")
Set tag(11) = gTagDb.GetTag("system\DayOfMonth")
Set tag(12) = gTagDb.GetTag("system\Hour")
Set tag(13) = gTagDb.GetTag("system\Year")

When I write those tags in my excel file, I get all the system tags and digital tags ok, but the analog tags are always 0.

I found that the system tags are defined as Unsigned integer. I changed one of my tags to that data type and then it was ok. I tried floating point but got the same result, always 0. How can I get floating point values???

Thanks for your help.

As a guess for question 1.
At run time try entering the value 50 and see if it displays as 0.50
as any number you enter may only be seen as a signed or unsigned integer that needs scaled by 0.01

I set this up exactly the same on a test screen and I do not get the error and it accepts .5 w/ no problems.

I found the solution. See technote 47066 from AB knowledgebase. It corrected both problem 1 and 2.

Thanks

gTagDB.gettag is for RSView....
Can anyone suggest similar thing for FTView......
