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:

1.Press  to open the Main Menu

2.Press (System Configuration)

3.Press (Network Setup)

4.Press (Network Summary)

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).
