DNI Configuration Parameters and Programming Notes 47

DF1 Substitute Address

If the device that is connected to the DNI is not capable of selecting a
DF1 destination address of 0…63, by entering a value in this
parameter, the DNI automatically routes all DF1 communications to
this address with the following exceptions:

• Responses to poll requests are sent to the configured address.
• COS/Cyclic I/O data messages are sent to the configured device.

For example, when using a MicroView operator interface over
DeviceNet, DF1 Substitute Address defines the device (node number)
that the MicroView exchanges data with.

DF1 Autobaud

The DNI’s RS-232 baud rate is set up to automatically synchronize to
the attached RS-232 device. If you want to lock the RS-232 baud rate,
disable this parameter. If this parameter is disabled (0), the DNI’s
RS-232 port baud rate is set to the value specified by the DF1 Baud
Rate parameter.
