TIA Portal v12: simulate HMI - no connection to PLC

I do not have much experience with TIA Portal (we still have a lot of projects on STEP 7 and WINCC).

Now we have a new project with TIA Portal V12: an S7-315CPU and a TP1900 HMI-panel.

Now I want to simulate the HMi-project on my PC, without succes:
 - PC connects to HMI-panel by ethernet
 - I can go online on the HMI
 - I can go online on  the PLC
 - When I simulate the HMI --> startscreen opens, but doesn't connect to the PLC (I/O is not correct). If the start-screen opens, there are some alarms, but they dissapear after a few seconds...

My settings:

- in HMI in TIA-portal - connections - S7ONLINE
- on my PC: Control Panel: PG/PC interface: PLCSIM.TCPIP.1

Hi,

if you connect to the real PLC then you must set in PG/PC Interface the Access point S7ONLINE to the Ethernetcard which is connected to the PLC!

You setting PLCSIM is for a simulated PLC needed, not for a real PLC!

 I have the same problem, BUT, I'm using the PG/PC interface S7ONLINE TCPIP1 etc (the good one).

I check the PLC-HMI connection, just in case, but It isn't the problem (I'm using simbolic tags).

Sometimes the HMI simulates and I can access the PLC tags, but, many times (like right now), It doesn't work (I see ### on it's place). 

I don't know where's the problem, or how must I check.

I will appreciate any kind of help or some ideas.

New question published by AminJalili is split to a separate thread with the subject How to connect the HMI simulation to a S7 400 simulated PLC?.
