Elements 3 of INT_array is the lower 16 bits of the amount of free I/O memory. 13 comments. If the two SINTs are in an array ( RcvSINT [0], RcvSINT [1] ) then COP RcvSINT [0] DestINT 1 should do it. Yes. MCM.DATA.ReadData[x] is a (16-bit) INTEGER data type. If you just want to see it in binary you can change the "style" of the tag. The project is located on the Emonitor version 3.50 software installation disk: \extras\RSLogix Application\ICM DATA APP.ACD The MSG instruction returns each memory value as two separate INTs. You will need to create a `COP` statement that copies both 16-bit Integer values into a single Real tag. Thanks Ken, the CPS instruction is the thing that I wasn't sure of, and I'll look it up and use it. (which I read many times over), Say to store the data in a "buffer array", then convert the Dint to Int by the FAL function block. I'm a little bit more familiar with moving a float to an integer in RSLogix 500, so does it work the same way in RSLogix 5000? If source A & B are not REALs, then the fractional portion of the result truncates. This would lose part of the data. MrPLC.com will not obtain or supply firmware on your behalf. REAL to DINT is an issue because you will get rounding or truncating errors. The COP statement here will take the one floating point value "SendFloat[0]" and place the data in the MCM.DATA.WriteData[0] and MCM.DATA.WriteData[1] tags for example, since a length of 2 was specified in the COP statement. We are currently experiencing problems with telephone access to our Australian support centre.
