Hi,

I have a question about real variables in Twido PLC's, it exists?

I want to scale an analog input, and I have to divide one operand to another one and I don't know how.

Thank you.

Check in your CPU manual if it supports %MF registers.

Hi,

This was for a Modicon (TSX37), but think the instructions are also supported in the Twido's?

Hope this helps.

Regards,

Rob

Thank you for answers.

It works with MF, but an important thing, when assigning direct values to this tata types variables you must use " , ".

Example:

%MF1:=5.0

Thank you.

Hi,

Be careful that the smallest versions of Twido doesn´t support %MF.
