De-Normalize the binary Data

[mike shaw]

Hey Guys,

I am kind of new to Omron PLC. Can someone please share details on how can we de-normalize the data in Sysmac Studio? 

1. Denormalize: 1.1011₂ × 2^-3 = 0.0011011.
2. Convert:

   Exponents	20		2-1		2-2		2-3		2-4		2-5		2-6		2-7
   Place Values	1		0.5		0.25		0.125		0.0625		0.03125		0.015625		0.0078125
   Bits	0	.	0		0		1		1		0		1		1
   Value							0.125	+	0.0625			+	0.015625	+	0.0078125	=	0.2109375

3. Sign: negative

Result: be580000 is -0.2109375.

I want to perform kind this operation in Sysmac studio. Any help would be appreciated.

Thanks

I am not clear on what you are trying to do here..... is this some kind of custom number format that you are trying to use?  I think what you would need to do with a custom format like this is to create a union.  The union will allow you to look at individual bits as well as a WORD or DWORD value.

i guess he is looking at interpreting 32-bit INT as a 32-bit REAL... 

in this case 0xBE580000 is actually -0.2109375

As Michael has suggested, a Union would be the easiest method to view it in different Data Types.

Where is the data coming from? Maybe we can help you simplify the process. If it is part of a group of data (EtherNet/IP for example) then a Structure may be helpful.
