Citect Equipment Parameter Address Offset with Multiple Params

[AVAutomaz]

Hi,

I would like to dynamically calculate the address, adding multiple parameters and a fixed offset.

The selected protocol is MODNET.

If i write only "{equipment.HC900_Addressing[Offset]}" with value 40001, it works.

The "formula" test I ran is this.

How can I write the address assignment, using the two parameters and the fixed offset?

Hi @AVAutomaz,

Unfortunately I can't see the "Formula" test in your original post.

I'm not sure if mathematical formulas are supported when creating the equipment instance.

I'll do some more research and let you know what I find.

Let us know more details and what version you are using.

Kind regards

Olivier

Hi @olivier_vallee,

i don't know why, but i see the image in my previous post only when i'm logged in.

I have attached the picture.

The version of citect Scada is 2018 R2.

Currently i am using a workaround: I changed the values ​​directly in the variable.DBF. But this involves editing with excel or libreoffice.
Also, every time I update the equipment, it is necessary to update the DBF again. I would like to do it automatically in Citect.

Hi @AVAutomaz,

Thanks for providing the image, it gives more context as to what you were trying to achieve.

I did a bit of research, and unfortunately the equipment template isn't intelligent enough to do the math operation you want. Perhaps it can be done in Excel after you have created the tags using Equipment Editor? To evaluate the expression?

I recommend posting a suggestion on the Plant SCADA AHA ideas portal: https://plantscada.ideas.aha.io/

Suggest that Equipment Templates or Equipment substitutions support basic math operations and also provide the example of what you are trying to achieve with your addressing in the variable tag.

Kind regards,

Olivier

HI @olivier_vallee,

Using Libreoffice (not Excel because I have Citect on Virtual Machine and Excel on Host) it is possible to edit the "Variable.DBF". I created a spreadsheet that transforms the resulting expression into the calculated number. Unfortunately, however, I have to perform this operation every time I update the equipment. I tried to add a new idea on the link. Thanks
