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.

I/O Network Commissioning

If commissioning an I/O Net device and multiple I/O Net ports are available, you will be prompted to select the appropriate network during the commissioning process.

Three I/O Net connections can be operational at the same time, and note that duplicate board numbers cannot be set up on different I/O Net connections. For example, only one board can be set to address "1" per board type across all I/ O Net connections. If there is more than one I/O Net con- nection defined, select which I/O Net connection the board is on from the Network Summary screen through the F4 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).

A menu will appear on the screen, giving you the option of either pressing the service button, entering the Neuron ID by hand, or canceling and returning to the main

screen. Press to select the service button option.
