CANNOT LINEARIZE NEGATIVE NUMBERS IN URA-0800T

[gongue]

hello everyone. I need help. I have a URA-0800T to linearize dew point from -100 to +23 degrees celsius. but the linearizer block only allows me to put UINT16 type tags on input A, and I cannot put INT16 type y1 and 2.
can anybody help me? Thanks in advance.

I´m able to place INT16 tags to C (Y1) and E (Y2), even A (input) is UINT16. Attach your program to take a look. Also, confirm Unilogic version

If you already have a UINT16 in E or F, it may not let you use INT16 in C. Make sure you're entering INT16 in C, E, & F.

hi

i think that the "problem" is that you select the input chanel of the URA-0800T analog reader module...this can has only UITN16 range and not negative value...linearization LFB is needed to conver the UINT16 range in the INT16 range...for example 4 mA (positive value) input means -100 (negative value) and 20 mA (always positive) means +23 (positive)...hope that is correct and clear.

Is it really that #65535 is the correct value  for 20mA in linearization for URA-0800T as Gabriel Franco noted (2 years ago)? This module has 16bit A/D, but "with sign" according to manual! Maybe #32767? And #6553 for 4mA?
