Hi

Struggling with this for some time now.

I have Logo8 connected to Logo CIM module to read modbus sensor data

sensor outputs 32 bits hex values

value 1 is eg*: 41c8 0000 which is 25 (degrees celsius temperature after conversion with floating point calculator)

i can read separately into NAI1 and NAI2 values which are shown as corresponding decimals 16840(41c8)  and 0 (0)0000

If i send the data directly to floating/integer converter then i dont seem to get logical output

any ideas how to get temperature readings correclty?

thanks!

yes but the whole value is 0x41c80000 which is 25 in floating point

0x41c80000 is also 1103626240 in dec. any way to convert that in logo to correct floating point to get temperature?

for testing is used this calculator(enter hex value to get correct temperature reading):

in simulator works like a charm! thanks for quick response!

just to verify the case i have

output of float/int converter will be 17784 which is 17.784 degrees

do i have to use analog amplifier or is there better way to get correct value right away

thanks
