Integrating Automation Systems
Definition
• Integration – bringing together separate systems or products into a single and seamless graphical user interface (GUI) which will offer full control and monitoring between systems.
Value Propositions
• Investment Protection
• Extend System Life Cycle
• Limited Tenant ImpactsLimited Tenant Impacts
• Single Seat Operation & Control
• Improved Operation & Performance
• Vendor Independence
• Save Money
Types of Integration
• System or Subsystem Level
• Integration of systems that would/could be standalone. (ie VFD, meters, chillers, etc.)
• Platform Level
• Integration of an entire BAS or Facilities Mgt System into a new GUI.
Platform Integration
• Integration can take place via a number of ways.
• Some integrations are dictated by system, version, system
architecture or available integration means.
• Common Integration Methods -
• BACnet, LON, OPC or Gateway (open or proprietary)
�Building Automation
�Fire & Life Safety
�Lighting
�Access Control or Video
• BACnet, LON, OPC or Gateway (open or proprietary)
• Typical integrated systems -
Considerations
• What manufacturer, model and vintage of the system we integrating?
• Many systems integrate differently.
• What is the network architecture look now?
• Get copy of network riser or sketch it out.• Get copy of network riser or sketch it out.
• Obtain “ALL POINTS” list where capable
• Understanding systems below / equipment counts
• Have we or someone else done this before?
• Where? Issues? Trouble? Unforeseen?
• Do we have people who know the system working for us?
• When in doubt….take pictures!

Benefits vs Draw Backs
• Benefits –• Can eliminate the Apogee OWS
• Auto-Discovery of Points
• No need to Siemens
• Tridium already a Climatec
• Draw Backs –• Needs one (1) JACE and RS232 and
driver for each MBC (worst case)
• Speed of RS232 connection is 19200kbps
• Tridium already a Climatec product
• Open conversion for integration of open OWS platforms
• Siemens Graphics can be modified to go into JACE
• Keep existing field hardware and wire
19200kbps
• May need additional network wiring

Benefits vs Draw Backs
• Benefits –
• Eliminate the Apogee OWS

• No need to Siemens
• Draw Backs –
• Must replicate all I/O directly connected to the MBC or MEC

• Brings all systems and points in a BACnet environment
• Keep existing field hardware and wiring
programmable TEC’s
• We now “own” the system (good and bad)
Other considerations with Siemens upgrade
• If an MEC is in place, replace with—• BCM-PWS
• BCM-ETH
• 1 BCM-FPCS
• 8 DI, 8 AI, 8 DO, 8 AO• 8 DI, 8 AI, 8 DO, 8 AO
• If an MBC is in place, replace with—• BCM-PWS
• BCM-ETH

• VLX and EXP modules or
• VLCs as necessary for I/O on MBC
