BMS Interface Card
BMS system configuration by others.
Enables units to be interfaced with most BMS, factory fitted, please contact Airedale.
A wide range of protocols shall be accommodated through the use of interface devices.
Available as a standard option are: ModBus/Jbus, Carel, SNMP, LonWorks, Metasys and
BACnet
Also available shall be Airedale’s own supervisory plug-in BMS card pCOWEB.
Based on Ethernet TCP/IP secure technology with SNMP features.
Requires no proprietary cabling or monitoring software and supplied pre-programmed with an IP address for ease of
setup.
Modbus/Carel BMS Connection
The Airedale controllers shall be able to communicate directly using the Modbus® protocol.
The Modbus® card shall be a small PCB (60mm x 30mm), which is plugged into the controller to provide it with the
following protocol support
●
Modbus® - JBus slave
●
RTU mode (Remote Terminal Unit) with 8 bit encoding and error handling using 16 bit CRC
●
Communication standard connection options of RS485 (multipoint) or RS232 (point-point)
●
Maximum Baud Rate of 19200
The data communication shall be asynchronous serial, 8 data bits, 2 stop bits and no parity (in total 11 bits/datum).
The data/parameters from the controller shall be represented within Modbus® registers, each register containing
information pertaining to temperatures, pressures, setpoint and status etc. shall be available to the site integration
company in a spreadsheet format
Lon BMS Connection
The Airedale controllers, using special serial cards, shall be integrated into LonWorks® networks. The RS485 and the
FTT10 standards shall be supported by the LonWorks® serial cards.
The two types of LonWorks® serial cards shall differ by the type of interface on the LonWorks® network side:-
●
FTT-10A 78 kbs (TP/FT-10)
●
RS485 39 kbs (TP/485-39)
pCOWeb
pCOWeb is a new generation of Airedale supervisory plug-in cards which make communicating with an Airedale unit
simply a matter of logging onto the office Intranet or via the web.
Based on Ethernet TCP/IP secure technology, pCOWeb shall require no proprietary cabling. It shall have little or no
setup on site and can be pre-programmed with an IP address prior to dispatch from airedale.
When adding to an existing controls scheme, please consult Airedale Controls to ensure strategy
compatibility.
