Hi there,

I need to monitor multiple datas from multiple CPUs on HMI TP1500 comfort

so I was wondering what is the max  number of CPUs to be connected to TP1500  as profinet ?

Also do i need to know more data than the CPUs IP addresses and DB addressing of each data in order to establish this communication ?

Hi,

The max number of connections you can create are 8.

See the manual

SIMATIC HMI HMI Devices Comfort Panels

In paragraph 8.10 it describes the number of connections.

In your project, when you have both the cpu and the panel and create an HMI connection between them, they information about address is automatically known.

Then you can just access the PLC tags from the WinCC project.
