The CPU supports the following maximum number of simultaneous, asynchronous communication connections for PROFINET and PROFIBUS:

• 8 connections for Open User Communications (active or passive): TSEND_C, TRCV_C, TCON, TDISCON, TSEND, and TRCV.
• 3 CPU-to-CPU S7 connections for server GET/PUT data
• 8 CPU-to-CPU S7 connections for client GET/PUT data

• HMI connections: The CPU provides dedicated HMI connections to support up to 3 HMI devices. (You can have up to 2 SIMATIC Comfort panels.) The total number of HMI is affected by the types of HMI panels in your configuration. For example, you could have up to three SIMATIC Basic panels connected to your CPU, or you could have up to two SIMATIC Comfort panels with one additional Basic panel.
• PG connections: The CPU provides connections to support 1 programming device (PG).
• Webserver (HTTP) connections: The CPU provides connections for the Webserver.

Hello javed88,

And in addition:

When you want to know how many connections you can make in Comfort panel.

Look in online help of TIA Portal and go to performance of Panel. There you will find the number of connections.

(Or try in WinCC Comfort, select your panel and make a number of connections with different S7-1200 CPU's, you will find out the maximum number )

Best regards,
