Hi there,

I have tried out the communication between logo and S7-1200 but now i am unable to read the correct scaled analog value from S7-1200 in logo. Is there any sample program available for this?  Thank you in advance.

The logo can only handle integers, no floating point.

If you have a Floating point, you need to convert into integer format. The number must not be greater than 32767 and not less -32768.

Example:

127.65 * 100 = 12765,00

12765,00 convert to integer = 12765.

This value to the logo and then in arithmetic instruction or other set 2 decimal Points.

Hi there, 

Thanks for your quick reply. It is very helpful.

Hi there, 

I have already do the multiplication of the scaled analog value at the TIA end. 

Now i am getting the value from S7-1200 in LOGO. 

Example is the analog value at TIA is 0.144, then i am getting 144 at LOGO. 

But i am not sure on how to convert it again to display it with the decimal point using arithmetic operation or any other. Is there any sample available. 

Please help. 

Thank you in advance.
