NOTE:
If a Host/Supervisory field panel references a UEC subpoint, the Host panel must be
upgraded to Firmware Revision 2.8.6/3.2.2 or later.
FLN Node Mode
When the UEC is operating in FLNnode mode, it has the capability to monitor points
from other devices, and recognize the point by device specific name, or BACnet
encoded name. However a point log display should show only points that reside locally
on the UEC.
Some functions, depending on the exchange of proprietary messages, such as
replication, and database download, are not available. BACnet Encoded names or
device specific names must be used for referencing external objects.
● Only visible to the Web Server when defined as a FLN device.
● Operates on the FLN without replication.
● Cannot be programmed from an ALN device, if added as an FLN device.
● Recognized as a Siemens device.
● Exposes application number and default subpoint.
● Supports failure detection of the UEC by other nodes.
● Limited support of failure detection of other nodes by the UEC, only when defined
as a node of interest.
● No global data such as BLN User account or State Text tables support.
● No database upload and download from Insight but database can be saved in
panel flash memory.
● Proprietary messages generated using HMI are processed as usual.
● Proprietary messages received using comm port from Commissioning Tool (CT)
processed as usual.
● Save, upload and download database information using Field Panel Web Server UI
(FPWeb UI)and Siemens Launch Pad.
● PPCL Assist for programming over the network using FPWeb UI and Siemens
Launch Pad.
● Field panel support for FIN Builder graphics with Firmware Revision 3.3.1 and later.
● Support for totalization for analog and multistate points with Firmware Revision 3.4
and later.
ALN Node Mode
When the UEC is operating in ALNnode mode, it retains the capability to monitor points
from other devices and recognizes the point by system name, device specific name, or
BACnet encoded name.
All functions depending on the exchange of proprietary messages, such as discovery,
replication, and database download, are available. System name, device specific name
and BACnet encoded names are supported for referencing external objects.
● Only visible to Commissioning Tool (CT) for editing and commissioning when
defined as ALN device.
● Time is synchronized with the Insight workstation.
● In the event of a network failure, the UEC independently maintains control of the
time and scheduling, trending, and alarming.
● An Integration FLN, with Integration Driver support for FPWeb allows FLNs to be
viewed and modified from FPWeb UI in Kiosk mod.
