Analog input value in Logi.CAD3

[johan.vandeglind]

Hallo,

I have a little problem that I can’t solve, I want to use the full 24 bit ADC of the AIO module in logi.CAD.

The 0 to 10 volts is displayed in a WORD value of 0 to 10.000 mV when I read the global input in Logi.CAD.
I want it to use the full 24 bit range of 0 to 16.777.216

Is it possible to processes the “0 to 10.000” mV to “0 to 16.777.216”,

The value 1 in logi.CAD should give a value of 0,000596

Kind regards,

Johan van de Glind

Hello Johan,

Please tell us a little more about your (physically) application. What's the reason for the need of such a high resolution?
With current version of logi.CAD 3 it is not possible to get a higher resolution as WORD (16 bit).

Hello Walter,

Thank you for your reply.
We made a measuring system for a hospital project.
We need to have the high resolution for the reasearch purpose of this system.

We chose the RevPi as control system in noledge of the 24bit ADC.

Hello Johan,

thank you for the details.
After further internal clarification I can give you the following information:
The data type for the analog value is provided by "Pictory" to logi.CAD3. I think we would also need some informations from Kunbus how to get a higher solution for the analog inputs.

Hello Walter,

Yes I had the same idea, thats why at first I emailed Kunbus, but they said I needed to ask it here because they don't answer technical questions.
Do you think you I need to email again?

Hello Johan,

for changes in this behaviour (resolution for analog value) some big changes in the whole implementation (at logi.cals and at KUNBUS) are needed.
