Revision History
1. Base
This Functional Description is based upon the User Requirement Specification (BJMC_MRS_HVAC_AHU11/12_URS_1.0) for HVAC Systems and P&ID drawing (BJMC_02_01_AHU11_PID ) i n it current version and describes all automation functions belonging to the PLC for this installation. Furthermore the OQ functional tests of the installation will be based upon this document.
2. Introduction
This description defines the required measurement, control and regulating functions of the Air Handling Unit, AHU11.
3. Interfaces to other Systems
3.1. Time switching functions
3.2. Dependencies
3.3. Energy management
3.4. Emergency power assignments
3.5. Topology of automations, operating system
3.6. User access
Every login, logout and all changes are logged in a log file; all dedicated people are mentioned in the authorization list. All access will be automatically reported, except the “everybody” access for information without action (resetting, parameter and software changes). The following levels of user access to the system will be provided:
