pane. Click to select (highlight) the
UART#
required. Refer to Figure 2-17. Click
OK
. The
UARTX Properties
dialog will open.
5. Using the drop-down menu items, select the parity, data bits, stop bits, baud rate, Comm Mode and RTS GPIO pin from the \
available drop down options (UART2 RTS = GPIO158, UART3 RTS = GPIO159). If you are planning to use structured text to
communicate with devices on this port, click the Enable ST buffers checkbox and enter the transmit and receive buffer size.
Refer to Figure 2-18. Click
OK
. The
UARTx Properties

Repeat these steps for all Serial Ports (UARTs) to be utilized on the VersaGateway Device. Once completed, the Serial (COM Ports /
UARTs) are now ready to be used in the ladder program. The Serial Ports may be used as Modbus Master / Slave, to Serially Print to
externally connected devices or can be used to communicate other devices by writing custom serial port drivers using Structured
Text.

To use Serial Printing feature with the Serial (COM/UART) ports, the Serial Print option must be installed in the ladder
diagram project before it can be used. Refer to the
Serial Print (COM Port) Section
of this manual for more information on
installing the Serial Print option.
To use Modbus Master / Slave over the Serial (COM/UART) ports, Modbus must be installed in the ladder diagram
project before it can be used. Refer to the
Modbus Master/Slave (COM Port) Section
of this manual for more information
on installing the Modbus over Serial port option.
