COMPACT
COMPACT Control System
General
Provision for communication and supervision is integrated
as standard into the COMPACT system.
The unit is ready to be connected via TCP/IP, and EIA-485
for supervision via existing system.
The following protocols can currently be obtained as
standard without an extra communication unit: Modbus
TCP, Modbus RTU, Metasys N2 open, BACnet and Exoline.
Communication can also be established via LON and
Trend using the communication unit (accessory).
The scope available for communication is conditional on
the software and programming of the same. The COM-
PACT air handling unit in itself offers possibility for overall
communication of readings, settings and functions.
Further information about interfaces, protocols and con-
figuration is available at www.swegon.com.
Web Communication via Network
Communication can take place via TCP/IP using an ordi-
nary internal network. All that is needed is an ordinary
computer with web browser, such as Internet Explorer.
Connection to the network can be done just as easily as
connecting a printer, for instance.
Comprehensive communication of values, settings and
function is available. In addition, there is also a mail func-
tion for forwarding alarms.
Logging
Logged values for the parameters desired can be selected
if web communication is used. The values are presented in
the form of a curve diagram that allows the user to review
prior changes made back in time.
Logging can also be carried out by connecting an MMC
card to the air handling unit’s control unit. The log files
can then be opened in the Microsoft Excel program, by
means of a standard MMC card reader.
Microsoft Excel can manage max. 65,000 log entries. If
you set 1-minute logging intervals, logging will then occur
during 45 days. If you set 5-minute logging intervals,
(actory setting)logging will occur during 225 days. 65,000
logging entries fill approx. 40 Megabytes on an MMC cir-
cuit card.
