The BACnet devices shall be connected on a peer-to-peer network using one of the approved LAN technologies such as Ethernet, ARCNET, MS/TP, LonTalk or BACnet/IP. Network: A system of distributed control units that are linked together on a communication bus. A network allows sharing of point information between all control units. Additionally, a network provides central monitoring and control of the entire system from any distributed control unit location. Operating System (OS): Software that controls the execution of computer programs and which provides scheduling, debugging, input/output controls, accounting, compilation, storage assignment, data management, and related services. Operator Interface Workstation (OIW): The OIW consists of a high-level processing personal computer and peripheral I/O devices that enable access to the PC and to the entire Management Level Network.

Refer to the definition of furnish. Router: A device that routes messages destined for a node on another segment subnet or domain of the control network. The device controls message traffic based on node address and priority. Media converters which serve as communication links between power line, twisted pair, fibre, coax, and RF media are sometimes referred to as Routers. Standard Network Variable Type (SNVT): LonWorks controllers use SNVTs to define data objects. Each SNVT is identified by a code number that the receiving controller can use to determine how to interpret the information presented. Standing Standard Project Committee (SSPC): ASHRAE terminology for a technical committee that oversees the maintenance of a standard. Software: Generic term used for those components of the computer systems that are intangible rather than physical. The term "software" is used to refer to the programs executed by the computer systems as distinct from the physical hardware of the computer systems and encompasses any programs such as operating systems, applications programs, operating sequences and databases. The term "software" shall be interpreted to include firmware if, in the context in which it is used, the term "software" does not exclude the use of read-only memory and the use of firmware meets all of the applicable criteria detailed in these specifications. Thin Client: Thin client technology involves delivering windows applications to client workstations from a centrally based server. The thin client workstation has the ability to process information but data storage, applications and administrative functions reside on the terminal server.

Each analogue and digital input point shall be scanned at least once every 5 seconds. If a point is in alarm, then the alarm shall be annunciated at the NIU within 2 seconds of the termination of the time delay period following detection of the alarm condition.
DDC outputs shall be updated at a frequency defined by the operator. The operator shall be able to select a frequency, at minimum, in the range of 2 seconds to 256 seconds. The operator shall be able to define a minimum time delay between successive starts of equipment so that disturbances created on the building electrical system are minimised in frequency and amplitude. It shall be possible for the operator to assign at least 6No. start times and 6No. stop times in any 24-hour period. BMS controller analogue and digital outputs shall change as the result of either an operator entered command or a BMS generated software command. These two modes of BMS controller output are referred to as the BMS MANUAL CONTROL mode and the BMS SOFTWARE CONTROL mode and differ as follows: 1. In the BMS manual control mode, the signal to a final control element such as a valve or a damper actuator and to a relay such as a motor control relay shall change as the result of a command manually entered at one of the operator terminals. When an output is in the BMS manual control mode, there shall be no means by which it can switch to the BMS software control mode or by which the value or state of the BMS output can change without operator intervention. In the BMS software control mode, the signal to the final control element or relay shall be changed automatically as the result of software such as a schedule, operating sequence or Applications Package such as the Optimised Scheduling feature.
The operator shall be able to select the mode of output control for each analogue and digital output. The operator shall be able to define the minimum time delay between the stopping of a piece of equipment and its subsequent restart. This time delay shall be in effect for motors in the BMS software control mode and for motors in the BMS manual control mode.

Unless stated otherwise elsewhere in these Specifications, the modulation of final control elements by the BMS controllers in the BMS software control mode shall be based on a Proportional-Integral-Derivative (PID) control algorithm. The control constants for the PID algorithm shall be definable by the operator. If self-tuning algorithms are provided, it shall still be possible for the operator to manually tune the control loops. The software shall incorporate facilities to enable the bumpless transfer of a modulating output from BMS manual control to BMS software control and vice versa and the prevention of integral wind-up. PID algorithms shall maintain the system operation within the desired tolerance around the setpoint. Setpoint tolerances shall be as follows: 1. 2. 3. 4. 5. 6. Supply air temperature control, + or - 0.5 Deg. C. Space temperature control, + or - 0.5 Deg. C. Duct static pressure control, + or - 50 Pa Water differential pressure, + or - 15 kPa. Space static pressure control, + or - 10 Pa Relative humidity, + or - 3%
Software shall automatically inhibit the generating of an alarm on an analogue input when the status of an associated digital input indicates that an alarm condition is to be expected. Such would be the case, for example, when an air handling unit is off as it would be expected that the supply air temperature would be outside the alarm limits established for the operating state. An interactive procedure shall enable the operator to link any analogue value to a digital input so as to inhibit unnecessary alarms. Points with their alarms locked out shall continue to be displayed on reports and VDU displays. The alarms shall remain locked out for an operator defined time delay following the start-up of the associated equipment If for any reason the operator wishes to terminate the monitoring of a particular digital or analogue input, then it shall be possible to take the point out of service via an interactive procedure. If the point is the monitored variable in a control loop, then the control loop shall be disabled, any sequence dependent on the point shall also be disabled and all associated BMS outputs shall go to the BMS manual control mode. An interactive procedure shall enable the operator to add, delete and modify points monitored and controlled by the BMS controllers. An interactive procedure shall enable the operator to configure control loops. The operator shall define Setpoints for control loops or they shall be derived from software logic as detailed these specifications. All configuration tools shall be provided to the Owner.
