gongue Posted February 21, 2023 Report Share Posted February 21, 2023 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. Quote Link to comment Share on other sites More sharing options...
Gabriel Franco Posted February 21, 2023 Report Share Posted February 21, 2023 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 Quote Link to comment Share on other sites More sharing options...
MVP 2023 Flex727 Posted February 21, 2023 MVP 2023 Report Share Posted February 21, 2023 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. Quote Link to comment Share on other sites More sharing options...
ORSO2001 Posted February 22, 2023 Report Share Posted February 22, 2023 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.

svg Posted May 5, 2023 Report Share Posted May 5, 2023 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? Quote Link to comment Share on other sites More sharing options...
