ASCII data send to modbus holding register issue

[johnson pay]

Hi all,

 

I'm using FX5U PLC, then using Ethernet TCP to received data from other instrument device, after received the data is ASCII code e.g 2.8934E+0, now I want to send this data through modbus RTU, e.g 

40001 = 2.

40002 = 89

40003 = 34

40004 = E+

I have doing some conversion but still get decimal code, anybody have do it before, I try a lot of method to convert the data, but still cannot

You should be using real values and instructions. E*, E+ etc

Not sure if I got this right: You want to send the "characters" as ASCII over a binary line (RTU)? You don't want to send the data as regular binary float/real values?
