Greetings,
8211 indicates that there is no communication between PLC and your Slave Device.
If you can get datas with modscan, it shows Slave device is up and suitable for communication.
You need to check your PLC configuration, modbus settings, register address and polarity of the cımmunication cable.
Hope it helps you.

You can also check that the com port you are using is configured as master (client) a common mistake that i often do.
