AVEVA™︎ InTouch HMI 2023 R2 SP1 P02 Technical support

I have a Tricon CX PLC Controller that is connected to:

1- Engineering Workstation that shall Have AVEVA Intouch window viewer and window maker on it, and a standalone HMI application
also, the workstation has a DDE server installed on it, Tags in the Intouch application will be connected to this server to read the tags and write tags to the controller

2-P6 Harmony PC BOX with 19’’ inch Touch Screen on the System Panel Door that shall have the same standalone application runtime working on it

3-Operators' workstation in another building connected to the Touch screen, Engineering workstation and the controller with a fiber optic cable and all the Components are connected to a switch, this workstation also runs the same Standalone runtime application on it

Note: The application has 2500 Tag, and all the Workstations and PC BOX have windows 10 Operating system

  1. Do I have to choose the application server product when installing the InTouch window viewer and window maker?
  2. Where can I get the Exact Part numbers of the AVEVA Intouch Licenses required for this setup and the description for the capabilities of each license?
  3. Do I need to purchase an SQL Server License or not or SQL Express will be enough, I'm planning to use the Alarm DB logger for historical alarms and events?
  4. How many tags and for how Long the Intouch HMI Data Logger Can Logs the data to view in historical Trends without AVEVA Historian installed?
