Configuring a Communication Port

Use the Communication Port Settings option from the Configure Menu to configure
the communication ports that will be used for communication with Siemens devices.
When this option is selected, this dialog box will appear:

Communication Port Settings

Note All communication ports can be configured without leaving this dialog box.
Repeat these steps; select a COM Port, set configuration, and click Save.
Select a communication port connected to the Siemens device.
Enter the amount of time (in seconds) that all PLCs connected via this communication
port will be given to reply to commands from the server.
Note This timeout is sustained only when the PLC fails to respond. When the PLC is
responding normally, there is no penalty. The default value of 1 second should be
sufficient for most configurations.
Select the Baud Rate (serial bit rate) setting that matches the configuration of the
Siemens device.
