Copy a REAL to DINT in a Rockwell PLC through a gateway. The codesys convert the DINT to a REAL. Have not worked with moving this data type, looked at adding the library for Oscat and install gives me errors. What about Rockwells copy is causing this and how could I convert this in the Codesys?

Hi

Why don't you * 1000 in the ab first transfer your data and then \1000 in codesys plc

So 23.123/ 1000 = 23123
Then in codesys plc

23123/1000 =23.123

oscat is very big, however when downloading the txt version you can take only what you need.

That makes more sense, figured I'd ask since the 2 should be the same data type.

Is the endian-ness the same? If not, you will need to convert that.
