Sending data to a Megelis HMI

Hello guys,

I'm programming PLC Modicon M340. I have reviewed the manual and the manufacturer says that this PLC can not handle variables with "flotating coma"(??? is that the right word?).

Problem is that in my aplication I'm reading REAL variables on analogic channels and I have to send this data to a Magelis HMI, and I don't know what kind of variable type to use in order to send it to the HMI. The HMI can accept WORD, DWORD, STRING, BOOL. Can some of you give some advice?

Every suggestion will be good. Thanks in advance.

Convert your data into word and in Magelis you can use INT for data type with 16 bits of data length.
You can also use data type is INT in Magelis with 32 bits of data length if you put it as DWORD in PLC.

Try that

Cheer,

The M340 can handle floating point, data type real.

Yip it can handle Floating point. Then in the xbt just set up the variable for floating point aswell

Thank you guys for your help. I will follow your recomendations.



Best wishes to all
