How to transfer counter value that is DWORD to VW analog output block.?

How to transfer counter value that is DWORD to VW analog network output block.?

I can not make connection, does it need to convert DWORD to WORD or any technics solveable.? 

What do you want to do with the counter value, transfer to another Logo or calculation ? For calculation you only can use a value between 0 and 32767, for transfer you can use VM mapping.

Describe your desired solution.

 Yes, I need a LOGO to read value of this counter in another LOGO. I config counter value in VM but it stated as DWORD. When I try to read by using NAI reading the mapped VM that is stored as DW, I got problem. You can try it and you could understand what I mean.

In the attachment a possible solution.

However, on this way can only counter values up to 32,767 transferred. Anything larger than 32,767 is interpreted as 32,767.

 

 Thank you very much...this is the same technic as I used to do. I just wonder if there is any function block that doing the conversion directly or not. Seem no function doing direct conversion for this task.  I just use counter value not more than 2000 and this technics should be no problem.

Thank you all.

 There is no conversion.

That is the LOGO! and no PLC. You always have to consider this difference.
The LOGO! is designed for integer values. Only partial areas are designed for DInt.

 Thank you Sir. I see there are Float to Integer and Integer to Float Function block. Could you explain what it is and a sample will be appreciated. Does DW is the same as Float..?

You have to know some basics of different integers, 16/32 bit signed/unsigned integer. Then you can interpret the values in a right way, see attachment for example.

No. A DWord in LSC is a double integer.
The function block that you mean is for converting a float value (32bit) or double float value (64bit) to a integer value, when the value is in the area -32.764 to32,767 to the output Aq.
The extented output eAq shows you in a message text values in a area from -999.999.999 to 999.999.999.

The actual purpose of the block is to convert float values from Modbus communication into integer values.

Integer (computer science)

Floating-point arithmetic

 Thank you very much. I need to study more about it.
