Setting the RS-232 / RS-485 Serial Interface

Open the configuration dialog for the serial interface module. To do so, execute
the command Settings in the context menu of the I/O module (node view or
navigation).
Important note:
Before changing the parameters you should save the current values in a
parameter file. This way, in case the parameters are wrong, you can always fall
back on the original values. Use the [Save] and [Open] buttons in the parameter
dialog.
The serial I/O module is configured and prepared for communication in the
configuration area.
In order to display the default values for this I/O module (except for the size of the
process image), press the [Default] button. The values indicated can then be
changed further.
To change settings in the serial I/O module, adjust the values in the configuration
area.
Changed settings are marked with a change symbol (pen symbol) in order to
indicate that these values no longer match the values originally queried by the
module.
To transfer the new values to the I/O module, click the [Write] button.
You can also put the I/O module into another operating mode. Here the changed
configuration is saved and the inputs and outputs of the I/O module are switched
immediately according to the operating mode.
