i uploaded an example of code
now i cant make it to scale bcd code to hex
now ull notice in code i have 2 scl3 cases, thats because i scale it for CX-Supervisor i have tempareture range from -50ºC to 150ºC and the tempareture regulator writes the tempareture in following format
-50ºC......FE0C
-0.1ºC.....FFFF
0ºC........0000
150ºC.......05DC
thats why i scale the negative value and positive value diffrently, actually i scale negative value from 0-499 and positive including 0ºC from 500-2000
now i just have to make it work the opposite way
some how it manages to get #08CA as result when i have #750 at D500, when the max result i should have is #05DC, and i do get #05DC when the value of D500 is #500
any ideas?
Edit: ok from what i can see from instructions i have to specify 5 parameters first is offset, second range of BCD area or ΔX, third is ΔY orrange of hex area, fourth is maximum conversion and fifth is minimum conversion
so for only scaling positive range of tempareture i would have to set, athleast thats how i understand
D330 #0000
D331 #1500
D332 #05DC
D333 #05DC
D334 #0000
but still doesnt works :(
