Node Address
The Node Address (network address) can be set with a software command using standard
DeviceNet protocol over the network, or manually using the two 10-position rotary switches
located on the top of the unit. Refer to
Data Rate and Node Address Switches
, page 39, for more
information.
DeviceNet Protocol
Attribute ID #01 defines the node address (network address) of the device. Any address from 0 to
63 can be used. The unit is shipped with the address set to 63.
Note
The node address switch on the top of the device must be set to the network
(PGM) position at power-up in order for changes to be made over the network.
Any changes in the rotary switch positions after power-up are ignored.
Node Address Switch Adjustment
Refer to
Node Address Switches
, page 40, for complete information on adjusting these switches.
Note
In order to control the network address directly from the switches, ensure the
switches are set to an actual value at power-up, and not to the network (PGM)
position.
When this condition is met, any changes to the address made through the network
are denied and the Attribute_Not_Settable General Error Code is returned to the
Set_Attribute_Single service.
Data Rate
The data rate can be set with a software command using standard DeviceNet protocol over the
network, or manually using the 4-position rotary switch located on top of the unit. Refer to
Data
Rate and Node Address Switches
, page 39, for more information.
DeviceNet Protocol
Attribute ID #02 defines the data rate of the device. The data rate can be set to 125, 250, or
500 Kb, where:
0 = 125 Kb (initial)
1 = 250
Kb
2 = 500
Kb
Note
The data rate switch on top of the device must be set to the network (PGM)
position at power-up in order for changes to be made over the network. Any
change in the rotary switch position after power-up is ignored.
