Hi,

I'm trying to communicate S7-1500 to Kp400 panel. I have successfully downloaded the PLC and HMI program using tiav19. I used the port of the CPU  x1p1 port for laptop and x1p2 for HMI with same subnet and set pg/PC using TCP/IP using my nic. However when I online my laptop and simulate some logic which is connected to HMi. The HMI doesn't have any responses from PLC like buttons, time, etc. I suspect I have wrong settings in security wizard or misunderstood that setup. Can I disable it like the old version so I can test my project. How? 

I have setup password in HMI connection to allso HMI access..it do have some progress but still I can't communicate to hmi.I have attached a photo an error message from HMI for reference

Hello braaay

which FW Version do you use in your S71500 and which Image Version do you have on your Panel?

(then we can say more about settings...)

If you want to simulate you have to check the PGPC Interface settings -> if you hae set the AccessPoint S7ONLINE in your HMI connection settings in the HMI project then you have to set this Access Point to the Networkcard.TCPIP.1 (if you wan to communication to a real PLC) or to PLCSim if you do also a PLc simulation on the same system.
