The biggest (and in my opinion, the most controversial at this point in time), difference between the IntelliCenter and ScreenLogic platforms (EasyTouch and IntelliTouch) is the way in which the user communicates from their PC/laptop to the actual control panel for programming/configuration changes.
When using an on-LAN device (PC/laptop), the ScreenLogic based platforms communicates from the computer directly to the ET/IT controller. This is accomplished through the use of a "protocol adapter". The protocol adapter connects to the user's router via a LAN port (Cat5/6) and then connects to the ET/IT RS-485 bus using a 4-wire conductor cable. This protocol adapter converts ET/IT machine language to computer machine language and vice versa.
Since this is essentially a "direct" or "local" connection. This method of connection has one huge advantage. It does NOT rely on the internet or the currently, poorly configured/maintained Pentair web servers to establish a connection between the user's PC/Laptop and the ET/IT control panel.
The IntelliCenter conversely uses the internet and the Pentair IntelliCenter web servers to establish this communications link.
In other words, the EasyTouch and IntelliTouch systems uses a desktop client and the IntelliCenter relies on a Web Client. The code and scripts for the ET/IT reside on the users PC/laptop. The code and scripts for the IntelliCenter reside on the Pentair servers.
While it may be a true statement that the IntelliCenter is much easier to receive and install firmware updates verses downloading and installing firmware for the ET/IT (not too easy), the biggest advantage to ScreenLogic is that it resides on the user's machine and not distant web servers. This disadvantage with regards to the IntelliCenter is further magnified greatly, due to the current inability of the Pentair Software Engineering and Development teams to respond to user's complaints regarding major problems with the IntelliCenter web scripts and coding and well as functionality for various mobile device apps.
Personally, I can find little wrong with the IntelliCenter firmware that resides on the actual IntelliCenter hardware at the control panel. All of the issues encountered by me are with the web client and the scripts and code (software) that reside on the Pentair Web Servers.
The best of both worlds would be to download the entire IntelliCenter web client scripts and code to a local machine (PC) and run them locally and cut out the web servers which would have the positive effect of emulating the principles of ScreenLogic. I have been able to see how the entire web assembly communicates between my control panel and the web servers using the Chrome developer tools but I cannot figure out yet how to download and run the package from my PC using my IntelliCenter's IP address. I'll continue to see if I can stumble on to something there.
Lastly, when it comes to using a mobile device such as iPhone/Android phone/tablet/Amazon Alexa/Apple Watch etc, then the ET/IT systems and the IntelliCenter are on equal footing. Both systems use the Internet and web servers, but with the exception of using the "local" feature on iPhone and Android apps.
NOTE: Currently the IntelliCenter Amazon Alexa and Apple Watch apps are inoperative. The software development team reported to tech support that they are aware of the issues and that was over a month and a half ago. I can only assume that these same apps for the ET/IT systems are functioning properly.
