FX16 Master Controller Technical Bulletin 67
Distributed Application
The FX16 Master Controller allows you to expand the I/O point and
control capacity by using a distributed application strategy. You can
connect up to 16 slave devices from the Facility Explorer field
controller family to the FX16 Master Controller Local Link Extension
Bus to be included in the Distributed Application. Each slave device
works independently and provides its own information to the network
through its application profile. The FX16 controller polls, refreshes, or
commands the network variables within the controllers to synchronize
the entire distributed application and to get it to work as a single
application. The distributed application is directly downloaded into the
FX16 controller and then the relevant parts are subsequently
downloaded by the FX16 to the connected slaves.
Gateway Function
The FX16 Master Controller (Rev. A) features the Gateway object. The
Gateway object can monitor up to 16 devices on the Local Link
Extension Bus that are not slaves to a Distributed Application. These
slave devices can be FX controllers fitted with RS-485 N2 Open
communication cards, N2 Open devices (UNT, VAV, and AHU),
Metasys system compatible devices (VND), or System 91 devices
(DX-9100 and TC-910x).
Web Server
The FX16 Master Controller features an embedded Web server that
allows a remote user, running Internet Explorer, to dial in and establish
a point-to-point communication with the FX16 and to browse alarms,
logged data, configuration parameters, and controller variables included
in the Web pages. The Web pages contained in the FX16 are developed
at design time through a dedicated plug-in of FX Builder. You can limit
the access to the navigation of the FX16 Web pages with several levels
of passwords to different users.
Communication Services
The FX16’s RS-232C communication card option allows the FX16
Master Controller connect to a modem (standard or GSM). The RS-
232C communication card also allows you to use a null modem to
connect with the standard communication port of a computer.
The communication services of the FX16 Master Controller are defined
in the software configuration in FX Builder. Using a modem, the
controller can send e-mails and SMS messages (only GSM modem) to
report events and trend logs.
