How to change floating point data type to ASCII in EcoStruxure Machine Expert - Basic software?

[beryllarachman00]

Hello guys, so I'm working on a project at my company where I was asked to make sensor readings printable with a serial printer. Here I am a little confused with the floating point data type if I change it to ASCII the value becomes random. Is there a solution to this problem? I thank you in advance. (sorry for my bad English)

If your float value is -0.01 and you convert this to ASCII then I would expect it to result in the following byte/character array values:
0x2D, 0x30, 0x2E, 0x30, 0x31

Depending on how the ASCII is stored, there may be a prepended length (0x05), maybe even 0x00,0x05 or 0x00,0x00,0x00,0x05 depending on the size of the length field (8bit, 16bit, 32bit).

It may also be terminated with a null character 0x00

I'm not familiar with the FLOAT_TO_ASCII function however, so you should refer to the manual for this function to determine in what format it will produce its output.
