Vision V130 Unsigned scaling

Recommended Posts


I have a problem.

I'm communicating with MOXA ioLogik from whom I read RAW value of Analog Input.

The RAW value is in range from 0 - 65535.

The calculated value should be from 0 - 500.

If I use Linearization FB I've got wrong number with numbers over 32676 (Signed Negative)

The PLC always assumes that it is calculating with SIGNED INTEGERS.

How can I overcome this problem?
