Logo! 8 for BMS

Can not answer in general like that.

Since you have to explain more exactly what you want to do with it exactly ....

As I already wrote, we can not make a blanket statement, we would have to know the project better. Your previous information is quite poor.

The LOGO!s of the series 0BA8 can handle the following hardware:
24 digital inputs.
20 digital outputs.
8 analog inputs.
8 analog outputs.

If you need more, you need an extra (or more) LOGO!. These can exchange data via Ethernet, including information about the status of the inputs and outputs.

When visualizing it depends on how demanding it should be.
The 0BA8 has an integrated web server, which you can call in the browser. It shows you virtual message texts of the LOGO! (like a display of the LOGO! or the TDE) and you can also use the virtual buttons to perform switching operations.
With the latest, completely new LOGO! 8.2, you can create your own pages for the web server with a free add-on program (Web Editor).
If you want it more demanding, then you have to buy an extra visualization software, which with the LOGO! can exchange data.
