10.14.2 Commissioning a Device

Once all records have been created and defined for all
devices on the Echelon Network, they must be "commis-
sioned." Commissioning is necessary for the E2 to identify
and establish communications with all devices on the net-
work.
To start commissioning, open the Network Summary
screen:

NOTE: A device may only be commissioned if
it is properly connected on the network and
powered up.
How Echelon Commissioning Works
Each device that is capable of communicating on a
Echelon Network has a unique 12-digit "Neuron ID" code
number that is hard-coded in a chip on the board. In order
for the E2 to begin communications with a unit controller
or another E2, it must know the device's ID number.
When a device is commissioned, its 12-digit code is
either entered by hand into the E2 (via the front panel key-
board) or sent across the network to the E2 using the
device's service button. Once the E2 knows the device's
12-digit ID, it establishes communication and gives the
device its user-defined subnet and node address. From that
point on, the E2 uses only the subnet and node address to
communicate with the device.
As mentioned above, there are two ways in which a
device may be commissioned. No one way is better than
the other in terms of effectiveness, but one of the methods
may be less difficult than the other depending on the type
of installation.
MODBUS Commissioning
If commissioning a MODBUS device and multiple
MODBUS ports are available, you will be prompted to
select the appropriate network during the commissioning
process.

10.14.2.1 The Service Button Method

To commission a device using the service button, you
must first set up the E2 to receive a service button signal,
and then press the service button on the device. When the
signal is received by the E2, the device will be commis-
sioned.
To set up the E2 to receive a service button signal,
move the cursor to the Controller Name field of the record
you wish to set up, and press  (SET ADDRESS).
