DNI Configuration Parameters and Programming Notes 41
Device Type
Select the device connected to the DNI’s RS-232 port. If you are
connecting an Allen-Bradley controller as a DeviceNet I/O slave
device, this selection is used by the DNI to determine the type of
communication commands used to read and write data.
To achieve the best communications performance you should use
these recommended combinations.
I/O Scan Enable
This parameter enables the DNI to scan/exchange I/O data with DF1
devices. If the DNI is being used in an application that does not use
this feature, disabling this parameter improves the DNI’s messaging
