Diadem DAC formula invalid mathematical operation

[Marse]

Hello,

I will disturb you with a short question, maybe easy for you but I didn't find a solution for my self ( I'm a novice in working with Diadem DAC)

I build a scheme and when I run it I receive an  error ( see attachment) "...invalid mathematical operation" and I don't know what is wrong.

Maybe I don't know how to work with the formula block, and maybe you can give me some hints.

Please have a look on this error (see attachment) and tell me what to do.

Hy again,

I came back with some auxiliary info.

I have seen that I need to use auxiliary variables, but I have 40 variables ( channels that I want to use in formula blocks) , and  I can't assign all as auxiliary variables.

How to declare the all 40 channels?

[_sabcat_]

Try formula without the ' character like this    Resistor100_1tens / 100

If you need 40 channels in one calculation then you need to divide the fomula into multiple formulas, each formula block can have max 10 channels.

Hi Marse,

It seems that you're using DIAdem 10.2. In this version there was a limit for the symbol name in the f(x) block of 16 characters. If you change the name it works fine (please have a look at the attachment). This is changed with DIAdem 11.0 or later.

Referring to your second question I'm not such whether I really understand the problem. Please can you explain what you would like to do?

Greetings

Walter

Hello Walter,

Referring to the  second question, I was thinking to transform all the 40 channels to auxiliary variables, so the formula can work, but I find out later that if I will change the name of the channels( to be shorter) it will work.

In Diadem 11 you don't have a limit of characters?

Thank you again for your help.

Best regards,

Marius

Hi Marse,

Sorry for the late response, but the last two weeks I wasn't in the office. Yes, since DIAdem 11.0 we don't have a channel name length limitation.

Greetings
