Could not Read data from 2 slave Modbus RTU

In status tab.
What is the last error ?

The one that im showing is already in status tab.

Click (+) Last Error and see details

Owh, my bad. This is what it says

[anssikone.fi]

Absolutely. Nothing in progress.

[umairyamin]

And why is that happening ? Should be no problem since I can read the data using Modbus RTU function block. Is it?

[anssikone.fi]

Your application seems to be stopped.

[anssikone.fi]

Start your program and check status / error messages again.

Now “Response CRC Fail” appeared.

Sometimes work for me

Add polling time. Try 5 seconds at first.

[umairyamin]

how do you add that polling time?

Finally, I am able to read the data from Modbus Configurator. The solution is only to change the cable from normal cable to profinet cable.

Thank you for your suggestion all this time.
