Modbus ASCII in UDP
The Modbus ASCII in UDP property page is selected for editing by clicking Modbus ASCII in
UDP in the tree control section of the IP Configuration dialog. When selected the Modbus
ASCII in UDP property page is active.
The Server selection selects whether the server is enabled. If this option is enabled the
controller supports incoming slave messages. Disabling this option prevents the controller
from processing slave messages. Master messaging is always enabled.
The UDP Port sets the port used by the protocol. Valid port number range is 1 to 65534. The
default value is 49153. This is a recommendation only. Consult your network administrator to
obtain a port if you are not using the default.
