Hi,

I have a project based on LOGO! 8.1 6ED1052-1CC01-0BA8,

Now is available new version LOGO! 8.2 6ED1052-1CC08-0BA0,

Could you explain to me what is the difference between LOGO! 8.1 and 8.2

Take a look at the product note:

Delivery release LOGO! 8.2

 Thanks for the link.

So, as I understand, differences only

Support of custom Web pages with Web server integrated in each LOGO! 8.2 basic  device.

I do not use it, so for me there is no difference.

it would be more useful, in my opinion, 

make an analog input with resolution more than 10 bits,

or make counters double integer

Hi,

LOGO! was created in the past to replace application with contactors, timing relays and so on.

For me the analogu resolution of LOGO! is fine. 

As more resolution as more noice and unstable analgue value. So I thing most of the LOGO! customer we run into problems with EMCEMV if the resolution will be increased.

 I agree with you, that (probably) many customers have enough analogu resolution of LOGO!,

but unfortunately I have a project where it is 10 bit not enough (and it is very important),

so I am in that small category of people who would like more resolution AI and counters double integer.

If you need higher resolution for analog signals, then don't use a logic relay but a proper plc. For this you get analog modules with better accuracy. You can't buy a mini car with rolls royce comfort for low price.

Alternatively you can search for Modbus TCP modules with higher resolution analog inputs. You can read the values in the Logo, if you setup a Modbus client. But the main problem is the integer arithmetic in the Logo, if you want to calculate something with the analog values. Depend on your calculation you will lose the resolution by roundings.
