The module diagnostics exists for the input as well as for the output direction. There are the two sub-registers Analog and Digital, that show the current values as numerical values.

The "Analog" (inputs) table always displays the unscaled raw values in the floating point format.

The following errors can be detected on the input side:

• No data are displayed:

• • No connection to the Modbus server.

• • Error message by the Modbus server, see Troubleshooting.

• Incorrect values are displayed:

• • The byte order is set incorrectly, see General module settings.
