FX16 Master Controller Technical Bulletin
14
Consider the following information when you work with the
connections details for FX slave controllers:
• FX16 supports a maximum of 16 Facility Explorer slave controllers.
All slave controllers may be in a Distributed Application or
monitored by a Gateway Object, or you can use any combination
that does not exceed 16 devices.
• Slave model types for a Distributed Application: FX05 Advanced,
FX06, FX07, FX14, FX10 Advanced, FX15 Classic and FX15
Universal
• An FX controller used as a slave must have an RS-485 N2 Open
plug-in communication card installed.
• Slave model types for a Gateway Object: FX controller with N2
communication card, N2 Open Vendor (VND) device, or System 91
N2 controller (DX-9100 or TC-910x).
• The appropriate N2 bus serial address must be set on each slave
device.
• Maximum bus length is 1,200 m (4,000 ft).
• Install a repeater (for example, RP-9100-810x) to regenerate the
RS-485 signal. You install the repeater in case more than
31 N2 devices are connected on the local link extension bus and/or
the local link extension bus length is more than 1,200 m (4,000 ft).
• Install 220 ohm end-of-line resistors at each end of the bus line
when the bus length is greater than 100 m (330 ft). When the bus
length is fewer than 100 m (330 ft), insert only one 220 ohm resistor
at the FX16 Master Controller end only.
• The distributed application is downloaded to the FX16 Master
Controller. Then the FX16 Master Controller downloads the specific
parts of the application to the corresponding FX slaves.
• Devices connected and monitored by the Gateway object must be
programmed and/or configured independently.
• Slave devices can coexist with XT91/XP91 modules on the local
link extension bus.
