Hello everyone,

The question is simple but for me the answer is a little cloudy.

1) I have two registers i can read from a flowmeter to form a floating value. One is R2610 and other is R2611.I need to place them such that they need to form a floating value however siemens keeps converting (only the high value to a form of float so i do not have any decimal value for ex;
R2610 : 17457
R2611 : 4090

However my value is converted like; 708.0 in fact it should be; 708.24963 sth.

With which block/blocks can i see the actual value?(Btw i am connected with Modbus over TCP/IP)
(i checked/read the values with a modbus slave program)

Thanks for help

Step 7 it is... V5.5 SP3

Merging two integers and forming a floating number is my problem....

Thanks for your kind interest...

In few word:
If your first register is for example DB10.DBW2 and your second register DB10.DBW4, in that case the real value is available into DB10.DBD2

If your register are not consecutive, copy them into two consecutive register...

You don't need to merge anything, just access two words as floating point:
