Hi,
I've a problem with connection PLC 1515F (F.W. 3.1) and TP1200 Comfort (V16.00). I can download soft to both devices but HMI displays errors - 140001 (connection disconnected) and 190011 (value could not be written to plc).

I set PG/PC interface S7online to TCP.IP., the same date on hmi and plc but it's not synchronize because NTP server doesn't respond (don't know if it matters). I tried to resolve problem with this
https://www.industry-mobile-support.siemens-info.com/en/article/detail/109820712 and article nr 69864408 from siemens but it doesn't help.

Problem existh both on simulation and real devices.

I attach some screens.

Hello,

Let start with the following link:

In WinCC (TIA Portal), how do you configure a connection between WinCC Runtime Advanced or HMI Panel and an S7 controller over Industrial Ethernet (PROFINET)?

Following the instructions for "Connection between HMI and S7 controller"

Perhaps you have more errors about connection? (About certificates?)

@edit: 

See the following link:

Configure an HMI connection to an S7-1500 CPU with FW V3.1

Best regards,
