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!

• Tridium Server

• Open Frontend


• 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

Alerton BCM-FPCS Gateway

• Foreign Protocol Converter Siemens

• 1 Siemens P1 LAN supports up to 32 TEC, MPU or DPU controllers

• 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

• Up to 3 BCM-FPCS modules

• VLX and EXP modules or

• VLCs as necessary for I/O on MBC
