Setting the RS-232/RS-485 Serial Interface
1.
Open the configuration dialog for the serial interface module by selecting
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.
2.
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.
3.
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.
4.
To transfer the new values to the I/O module, click the
[Write]
button.
