● The HMI prompt was changed from A, N, M
(Application/flNdevice/Mstp) to A, N,
B
(Application/flNdevice/Bacnet); allowing the
configuration of routed FLN types and clarifying
that any BACnet device (MS/TP or IP) can be
added to the BACnet ALN.
● The Available memory report has been extended
to show installed Memory (physical memory
installed in hardware), in addition to the existing
metrics already provided:
– Available RAM left
– Number of Fragments of memory
– Largest Contiguous memory
● Auto Save allows the database to be backed up
to flash memory automatically whenever the
database is changed, instead of being an
operator-selected function. It does not provide
any safeguard or protection against power loss.
● PXM10T and PXM10S support: Optional LCD
Local user interface with HOA (Hand-off-auto)
capability and point commanding and monitoring
features.
● MS/TP Point Pickup Module (PPM) support:
Universal Inputs can be configured for analog or
digital input. Input/Output type is configured by
writing to BACnet object properties.
Hardware
TC Modular
● The TC Modular is a microprocessor-based multi-
tasking platform for program execution and
communication with other field panels. It scans
field data, optimizes control parameters, and
manages operator requests for data in seconds.
● The program and database information stored in
the TC Modular memory is protected with a
battery backup. This eliminates the need for time-
consuming program and database re-entry in the
event of an extended power failure. When battery
replacement is necessary, the TC Modular
illuminates a “battery low” status LED and can
send an alarm message to selected printers or
terminals.
● The TC Modular firmware, including the operating
system, is stored in non-volatile flash memory.
● The TC Modular provides both an Ethernet port
as well as an RS-485 port for communication on
Automation Level Networks supporting either
BACnet/IP or BACnet MS/TP.
● LEDs provide instant visual indication of overall
operation, network communication, and battery
status.
● Two self-forming buses are an integral part of the
flexibility of the TC Modular. A self-forming bus to
the right of the controller (see Figure 3) supports
up to 500 points through TX-I/O™ modules.
Another self-forming bus to the left of the
controller (see Figure 5) supports hardware
connection to subsystems through Expansion
Modules.
TX-I/O Modules
TX-I/O Modules are modular expansion I/O consisting
of an electronics module and terminal base. The
electronics modules perform A/D or D/A conversion,
signal processing and point monitoring and command
output through communication with the TC Modular.
The terminal bases provide for termination of field
wiring and connection of a self-forming bus. For more
information, see the
TX-I/O Product Range Technical
Specification Sheet
(149-476T).
TX-I/O Power Supply
The TX-I/O Power Supply provides power for TX-I/O
modules and peripheral devices. Multiple Power
Modules can be used in parallel to meet the power
needs of large concentrations of I/O points (see
Figure 2 and Figure 3). For more information, see the
TX I/O Product Range Technical Specification Sheet
(149-476T ).
