[?+]: Issue with Displaying Tags on HMI TP900 Comfort in TIA Portal

[SOV_AV]

Update: I found a solution to the problem = different Clock/Times PLC/HMI denied show tags for new firmware PLC and HMI
https://support.industry.siemens.com/cs/document/109820712

For an HMI with firmware V17.0.0.6 to connect to a controller with SSL/TLS encryption,
the date and time of the HMI must be within the validity period of the controller's SSL/TLS certificate.
If the date and time on the HMI are current, a connection to the controller should be established.
The time of the controller is not taken into account in this case.

Time synchronization between the HMI and the controller only works if a connection is successfully established.
For this reason, it is absolutely necessary to set the time before the first connection is established.

--------- Issue with Displaying Tags on HMI TP900 Comfort in TIA Portal -------------
Hello, esteemed forum members!

I've encountered a problem while working with TIA Portal and the HMI TP900 Comfort panel.

Problem Description:

The HMI TP900 Comfort is connected to PLC 1510SP-1 PN.

Device IP addresses:

PLC: 192.168.0.1

HMI: 192.168.0.2

Subnet mask: 255.255.255.0

In TIA Portal, the connection between HMI and PLC is configured via "HMI_Connection_1".

Tags from the PLC are imported into the HMI and linked to the corresponding objects on the screen.

However, when running the project on the HMI, data from the PLC is not displayed.


Additional Information:

In TIA Portal's Topology View, the HMI port appears greyed out.

I have successfully pinged both the PLC and HMI from the programming device (PG), confirming network connectivity.

Additionally, I pinged the PLC from the HMI's command prompt, and the ping was successful.

Despite these successful pings, the connection in TIA Portal remains greyed out, and data is not displayed on the HMI.


Steps Taken:

Verified the physical connection between devices — everything is in order.

Ensured that IP addresses and subnet mask are correctly configured.

Recompiled and reloaded the project into both HMI and PLC.

Checked tag settings and their linkage to screen objects.

Question:

Could there be any additional settings within the HMI that block data display? Are there any physical switches or software parameters that need to be checked?

I would appreciate any advice and recommendations.

thanks for the tip, it doesn't help

I’m facing an issue with my HMI TP900 Comfort and PLC 1510SP-1 PN in TIA Portal.
The HMI (192.168.0.2) and PLC (192.168.0.1) are connected, and pings are successful.
Tags are imported and linked, but no data displays on the HMI, and its port is greyed out in Topology View.
I’ve checked IP settings, recompiled, and verified connections.
Any ideas on HMI settings or PROFINET configs I might be missing? Thanks!

Good day, I found a solution to the problem!!!! It's just a joke,
I had different times in the Panel and the controller, set the same time everywhere and it should work!!!
