Dear all,

Today I wanted to create some PLC / HMI project using TIA Portal V12 SP1 (Step7 Professional V12 SP1 , WinCC Professional V12 SP1 and PLCSIM V12 SP1).

I can, after starting the simulation (PLCSIM) download the PLC HW and software and it runs. I can see the blocks / networks online and even modify the data (for instance state ofmerkers from 0 to 1). It seems to be working OK.

I can also run the simulation of the HMI project , screens work OK, like jump from one screen to another ( using the button that activates scren ).

Butwhen I try to influence my PLC data from myHMI , for instance by using the button that sets the merker bit in thePLC, then I get every timeError "$190011: value could not be written to the PLC".
Itried all the things I know, rebuild hardware, software blocks, saved, downloaded again, and still cannot solve this isue. I think that the Connection settingsare OK, like Devices & Networks, seem to be fine.
Inthe "old, traditional"Step 7 V5.5 SP3 withWinCC flex 2008 SP3 when I test projects I use simulator PLCSIM, download the project, run the HMI Runtime and it always works. No special things required or neded.

My V12 SP1 project contains of CPU1511-1PN and10''PN Color panel.I tested it also in environment V12 without SP1, the same problem.

Are there any additional settings or thing I have to do or set in?

Please help.

Hi guys,

💁🏼I have the same problem when connecting real PLC to HMI in simulation.

✅Solved by changing the PG/PC interface to TCP/IP

🔹PLC -S7 1200

🔹HMI - TP Comfort

🔹TIA - V17 

Please let me know if you need additional details, ✌🏼✌🏼✌🏼

Hello,

I would like to inform you that when I selected the stromdurchflutung 2 circuit then HMI screen shows negative value -0A. But once I magnetized the machine by footswitch then clamped the machine then current flow over the workpiece happened then we received the output value, we received the accurate value, our program is okay. After again negative value comes at standstill position, when the job has finished.

Negative value holding until activated the circuit. Without any activities, the negative value stay on the HMI. Once the output activated then we received the expected result.

salut, 

tu as fait le changement dans le panneau de configuration du pc ou dans "online access" de l'IHM ?

MERCI 

Hello joval972,

Hi there,

did you make the change in the pc control panel or in "online access" of the HMI?

THANK YOU

First, I reallt thank you for sharing this since it was my headache. 

Here is my question. If my HMI hardware is v-13, and TIA is v-15, I need to simulate in HMI v-15, then  change the HMI version to v-13 again then download to phisical HMI?

Hey I found solution. In SET PG/PC INTERFACE in Acces Point of the Application u should set CP_L2_1 -> Ur network Card
