Hi,
How I can get information about no communication with Modbus TCP slave (1)?
I want that signal to add red crosses on HMI informing that the displayed variables are not up to date.

HI @pawel_kowalski_ ,
In Machine Expert if you are using the Ioscanner you can check the Healthbits like this
You can always have a bit blinking on the PLC side and if it does not change the value you can trigger an alarm in the HMI or use a variables that in increasing his value.
If you want to avoid this you can create a variable in the HMI that checks the statistic of the communication using the address "@sys:2" if you get the 1 it means no connection to the device.
I hope this can help you and if this solves the problem remember to put the comment as solution 🙂
Best regards,
LeTomas
