TOPS Data Sheet
When operating in this mode TOPS devices are able to receive
data to, global to and data from IC comms messages from an
IQ3/IQ4 controller and reply to data from IC comms with the
correct value. This enables values to be transmitted between
IQ3/IQ4 controllers, and the 3rd party devices using IC comms.

In the diagram above the TOPS is operating in bound mode and
forms an internetwork with other Trend devices on the Ethernet
network forming an IQ system consisting of Lan 20, Lan 21, Lan
22, and Lan 23. Lans 20 and 21 are normal Lans consisting
of IQ3/IQ4 controllers. Lan 22 is the Lan that contains TOPS
and consists of two IQ3/IQ4 controllers, TOPS itself, and the
vCNC inside TOPS. Lan 23 is a Lan of TOPS devices. The
963 connects over Ethernet to the TOPS vCNC and is able to
access all the Lans.
Conguration: TOPS conguration is carried out using a
number of web pages that lead you through the conguration
process.
System Tray icon: The TOPS system tray icon provides access
to TOPS features. Right click the TOPS icon for the following
options like: License TOPS, Reset TOPS project, Start TOPS,
Stop TOPS, TOPS conguration, and View License. ‘TOPS is
online’ is also displayed when TOPS is connected.
Reset: TOPS can be reset to operate as a fresh installation. The
reset will reset the cong.bog le, navle, histories and alarms.
FUNCTIONALITY (continued)
TOPS can operate in one of two modes:
Standalone
Bound
Standalone mode: When operating in standalone mode
connection to TOPS is via its vCNC. The device connected to
the vCNC will have access to the 3rd party system(s) via the
TOPS Lans and TOPS devices inside TOPS linked to the 3rd
party devices.

The diagram above shows TOPS operating in standalone
mode. There are two Lans, Lan 22, and Lan 23 joined by an
internetwork. Lan 22 is the Lan that contains TOPS and consists
of TOPS itself, the vCNC inside TOPS, and a vINC. Lan 23 is a
Lan of TOPS devices. The entire system is built inside TOPS.
The 963 connects over Ethernet to the TOPS vCNC and is able
to access all the devices on Lan 22 and 23.
Note that the 963 has to have a separate connection to any IQ2
or 3 controllers which may be present
Bound Mode: When operating in bound mode TOPS joins
with the IQ network to which it is connected to form one large
network including the TOPS Lans and devices. Connection
to TOPS can be via any vCNC on the network although it is
recommended that connection be made using the TOPS vCNC
The device connected to the vCNC will have access to the 3rd
party system(s) via the TOPS Lans and TOPS devices inside
TOPS linked to the 3rd party devices, and all the devices on the
Trend IQ network.
BACNET DRIVER
The TOPS BACnet driver provides the ability for TOPS compatible devices to communicate with devices on a BACnet network. 963
is able to read values from, or write values to the BACnet devices, to receive alarms from those devices, and obtain BACnet Trends.
Objects in the BACnet devices are mapped to Trend modules in
the TOPS devices.
BACnet analogue input objects map to Trend sensor modules.
BACnet Property Read/Write Trend Parameter
BACnet binary input objects map to Trend digital input modules.
BACnet Property Read/Write Trend Parameter
BACnet analogue output objects map to Trend analogue driver
modules.
BACnet Property Read/Write Trend Parameter
BACnet schedule objects map to Trend time zone modules.
BACnet Property Read/Write Trend Parameter
Note: TOPS Supports only Boolean schedules.
