DNI Configuration Parameters and Programming Notes
5-19
DF1 Substitute Address
If the device that is connected to the DNI is not capable of selecting a DF1
destination address of 0 to 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.
