Why this presentation
 Digital technology offers data to be


transfered
BMS became available for
management tasks
A network is needed to carry over
data
This presentation offers information
and criteria to decide for the best
network solution, based on
functionality and costs

Pro’s and Con’s…
Automation network
n
Autonomous network
– Availability guaranteed
– Operational at hand over
– No interaction with ICTdept.
– Initial costs in
HVAC- or E-specification
– Extensions costly
– No Service Level
Agreement (SLA), however
maintenace needed
IP
Office network
– Allowed?
– Availability depends on
ICT-dept.
– Owner must be known in
construction phase
– Fitted after hand over
– Interaction with ICT-dept.
crucial for succes*
– Extra costs in ICTspecification (fairly low)
– Low cost extensions (if the
network is present)
– SLA needed, increases
operating costst

Virtual LAN’s (VLAN)
BMS Server
and
WEB-server
BACNet
VLAN1
VLAN3
RDP, HTTP
VLAN2
DDC-controller
DDC-controller
Geen verbinding!
Reasons voor VLAN’s:
• Separation of use
• Reduce cross segment traffic
Web client or Remote Desktop

BMS on the right spot?
 BMS workstations in most cases
– In most cases physically unprotected
– Back-Ups not frequently
 The better solution
– BMS server in ICT-environment (MER)
– Service Level Agreement (SLA)
for hardware and software maintenance
 New
– Hosting Services in
Cyber centers / data hotels
lower investments in ICT
