6. By default, each XJ Scroll's board number in the network list is indicated by a - (dash). To set the address
and begin communication, press D to Commission. (If you have more than one MODBUS network, spec-
ify to which network you want the device to belong.) A screen will open that will allow you set the address:
7. In the list of MODBUS devices, choose the address number corresponding to the XJ Scroll One-way Com-
munication Board address dip switch setting, and press
selected, its name will be shown next to the network ID in this list. If the network ID you are trying to assign
has already been used, you must set the network ID dip switch on this device to a different number that is not
being used.
8. Repeat Steps 5 and 6 until each XJ Scroll device has been commissioned.
9. When finished, press J to return to the Network Setup menu, then press
the XJ Scrolls you set up, and look at each device's status in the Status field. You will see one of the follow-
ing messages:
•Online - The XJ Scroll is communicating normally.
•Offline - The XJ Scroll is not communicating, has not been commissioned, is not functional, or is not pow-
ered up. Verify the XJ Scroll is powered up, wired correctly, and has the proper network address, baud rate,
and parity.
•Unknown - The XJ Scroll is not communicating or has not been commissioned. Verify the XJ Scroll is pow-
ered up, wired correctly, and has the proper network address, baud rate, and parity.
•No Port - No port is set up in the E2 Serial Configuration Manager to be a MODBUS port.
•Wrong FW Rev - This message is likely caused by the XJ Scroll having a firmware version older than the
minimum revision required by E2 for communication. Replace the XJ Scroll One-way Communication
Board with one that has the latest version of firmware on it.
