Figure 4-3. DeviceNet rotary switches and LEDs

Use the NODE ADDRESS rotary switches, MSD and LSD, to select the unit's address (MAC
ID). MAC IDs 0 through 63 are valid. Use the MSD switch to select the MAC ID's most
significant digit; use the LSD switch to select the MAC ID's least significant digit. Switch
settings greater than 63 (or in the "PGM" region of the MSD switch) let you configure the
MAC ID via DeviceNet.
Note: If your dual Pinnacle unit has two DeviceNet cards (one for each side), it is important
that you set the combined NODE ADDRESS of the first card to a different setting than
the combined NODE ADDRESS of the second card. If you do not, one side will fault
when the network is brought up.

Operation

You may operate your Pinnacle unit either through the 15-pin User port (user control mode)
or through the DeviceNet port (host control mode). To operate your Pinnacle unit through the
DeviceNet port, you also must have a connection to the 15-pin User port. DeviceNet operation
entails the use of User port pins 11 and 12.
For best results during DeviceNet operation, do not create a connection between pins 4 and 9
on the 15-pin User port. Closing and opening a connection between these two pins overrides
output on and off signals from DeviceNet.
When the Pinnacle unit powers up, it defaults to user control mode and power regulation
mode. Engaging DeviceNet places the unit in host control mode and power regulation mode.
Before operating your Pinnacle unit through the DeviceNet port, ensure that your network
connects with User port pins 11 and 12 as well as with the DeviceNet port. (But ensure that no
connection exists between pins 4 and 9 on the User port.) Also ensure that you have selected
an appropriate MAC ID and baud rate. Finally, ensure that you have read the following
information about command and respond messages and the DeviceNet LEDs.
