MTP700 communication with s7-1200

Hi miguel_villalobos145,

Congratulations on your first post! As you post more often, you will learn to provide more information (including screenshots, version information, etc.) to make our job as volunteers easier.

Without changing the default properties of the HMI screen elements, a connection error will usually result in yellow triangles with exclamation marks appearing in the background of the elements. So, without seeing what it looks like on your device, I assume it looks like this. For beginners, the most common reason for such communication problems is related to the security features introduced with TIA Portal V17.

By default, communication is secured and to establish communication, the PLC certificate must be valid and the PLC and HMI time must be almost the same. When the certificate is created in TIA Portal, it is valid for 10 years by default. So the certificate itself should not be the cause. However, you must set the PLC clock to a value within the valid certificate period. If you have never set the clock, this would not be the case. Once the PLC clock is set to the correct value, set the HMI clock to the same value and test again.

If you set an alarm control on your HMI screen, you will see a system warning with more details about the communication error. The message (and ID) may not be of much help to you, but providing this information to the community may help.

Kind regards
Stefan

Good day;

    I am trying to use a MTP700 unified panel to plc 1214 dc/dc/dc, but I can not get it. I am using Tia portal V17. I Can not read or write any tag from the HMI to plc.

    Any help, I will appreciate. 

 Hello miguel

do you still need help?

Do you work with real RT and Real HW or both in simulation?

do you get any errors in Alarmcontrol?

could you provide some screenshots of the behaviour?

Which FW Version does your PLC have?
