4 1. OBJECTIVE The aim of this document is to establish guidelines for the development of Process, System and Equipment Specifications for implementation within ActewAGL Treatment Branch Plant Control and SCADA Systems. Adherence to these guidelines will ensure a uniform standard of Specifications; in particular, appearance, format and content requirements. Adherence to these guidelines will also allow the Specifications to be maintained for the life of the processes, systems and equipment by ensuring that additions and other amendments can be integrated into existing functional specifications. 2. SCOPE These guidelines shall apply to Process, System and Equipment Specifications relating to ActewAGL Treatment Branch Plant Control and SCADA Systems. 3. DEFINITIONS The following abbreviations and definitions are used within these guidelines: Approved Quality Procedure LMWQCC SCADA FOIP HMI Approved by the Principal s Representative. Existing management system procedure, instruction, standards or specifications established by ActewAGL Treatment Branch Lower Molonglo Water Quality Control Centre. Supervisory Control And Data Acquisition. A primary means used to remotely monitor and control industrial processes, predominately from a central control room. Field Operator Interface Panel. A secondary means used to remotely monitor and control industrial processes, predominately closer to the equipment in the field. Human Machine Interface. A means used to remotely monitor and control industrial processes. This could be applied to both SCADA and FOIP. 4 Apr of 43

5 LCS Instrument Loop Local Control Station. A local means to control the equipment, usually located in the immediate vicinity of the related item and commonly consisting of push buttons/lamps/dials, etc An instrument loop consists of all items, cabling or pipe work used to measure, transmit, indicate or process an electrical or pneumatic analogue signal. An instrument loop generally consists of all items linked by a single current, voltage or pneumatic loop. For the purposes of simplicity the term instrument loop terminology may, however, also be extended to cover discrete digital signal control devices which do not relate to a single specific instrument loop or primary equipment item; i.e. Common pressure switch, flow switch, etc. Each instrument loop is identified as per ActewAGL Treatment Branch Quality Procedure TB 8.1 P601 (3.1.3) with reference to TB 8.1 P601 T3. Plant Equipment Item Each major item of plant equipment is identified as per ActewAGL Treatment Branch Quality Procedure TB 8.1 P601 (3.1.2) with reference to TB 8.1 P601 T3. Asset Hierarchy Essentially this procedure states that each item of equipment shall be uniquely identified according to its location and function. An ordered and structured list of plant equipment and instrument loops, with their equipment and loop numbers, arranged into a systematic hierarchy to bring together the various processes and systems within those processes by which the plant functions as a whole. 4 Apr of 43

7 5. GENERAL The purpose of a Specification is to define the requirements of a control and SCADA system with enough clarity to allow a programmer to develop the PLC/RTU application program and the Operator Interface for the facility being controlled. A secondary purpose is to provide maintenance and operational personnel with a clear statement of the role played by each item of the plant and how each item within a system interacts with the other items Document Structure The structure of the Specification is based on the ActewAGL Treatment Branch Asset Hierarchy. A brief overview of the Asset Hierarchy as applicable to the Specification is detailed below: Level 1: Example: LMWQCC Level 2: Plant/Facility Major Processes (grouped by Plant/Facility) Example: Primary Treatment, Tertiary Treatment, Solids Management processes at LMWQCC Level 3: Systems (grouped by Major Process) Example: Backwash Water Supply, Waste Backwash Water systems within the Tertiary Treatment Process Level 4: Individual Items Of Equipment Or Instrument Loops (grouped by System) Example: 5301PU, 5302PU Backwash Supply Pumps, part of the Backwash Water Supply System Each plant/facility, major process, functional system and individual item of equipment and instrument loop shall have a functional specification developed. At the plant/facility and major process level the functional specification will normally be an overview description of the plant/facility or major process and will also identify each of the lower level major processes or functional systems respectively that constitute that grouping. 4 Apr of 43

8 Similarly, at the functional system level, the functional specification shall describe the operation and role of that system in the higher-level process, to which it belongs. The functional specification for each individual item of equipment and instrument loop shall describe in detail all aspects of the operation of that particular equipment item or instrument loop. The specific data and information requirements for each level of Specification are detailed in Section 6 of this document. Further to the requirements of Section 6, an extra component is included in the plant/facility level functional specification to identify the revision status and/or date of issue of the Plant s Asset Hierarchy used for the Specification. In addition to the plant/facility, major process, system and individual equipment/instrument loop components of the ActewAGL Treatment Branch asset hierarchy, the ActewAGL Treatment Branch Specification also includes an ActewAGL Treatment Branch Standards component (at Level 2). This component describes the standard equipment and instrument loop control and SCADA functionality to be applied in the plant control and SCADA systems. The ActewAGL Treatment Plant s Specification shall consist of a number of individual files residing in a common directory (e.g. LMWQCC on Jeeves /LMFunc-Spec). The filenames used shall be as defined by the ActewAGL Treatment Branch Operations & Process Manager based on established practice. The Specification files shall be written in Microsoft Word format. All references to Standard Logic, Sites, Systems, Processes and Equipment (as defined in the Asset Hierarchy) shall be hyperlinked to the appropriate document (refer Attachment A for examples) Approval Status during Development During development, all approved text shall be coloured auto (black on a white background, white on a black background). Text submitted for approval shall be coloured blue. Other colours may be applied to text under development, these colours and their usage is not defined Specification Templates (Under Development) ActewAGL is currently developing blank functional specification templates. When available, these will be issued to the functional specification developer so that consistent format/styles are adopted. Until these documents are issued, the functional specification shall use the same formatting styles contained within the examples in Attachment A. 4 Apr of 43

9 6. FUNCTIONAL SPECIFICATION The Specification shall be contained in the descriptive text and tables following the site, process, system and equipment item/instrument loop headings. The information in the specification shall be divided into the following sections using the following subheadings. The detail required is dependant on the aspect being described. The ticks ( ) show the sub-headings required for the various aspects (site, process, system, equipment item/instrument loop). The asterisk (*) indicates where a sub-heading should be included only where required for the particular application. For instance, there may be specific Data Archiving requirement at the site level such as plant throughput or plant availability. Where a required sub-heading has no meaning for that particular level, include the sub-heading with a note that it is Not Applicable. Equipment item - static is for use with items with structure but without plant process control system connections e.g. tanks & channels. Any value within a configurable table cell that is not applicable is not to be left blank, but shall be marked by the symbol -. If an entire row is not applicable, then the row is to be deleted. There is to be a top-level document, defined by the Site/Plant asset hierarchy labelling scheme, (e.g. WWG Googong Water Treatment Plant) linking all the separate documents forming the complete functional specification. See the following example: 4 Apr of 43

16 Automatic Sequences: Identify all automatic sequences this unit performs or takes part in including start permissives, startup sequence, running sequence, shutdown sequence, emergency shutdown sequence, etc. Each item/equipment that is relevant is to be individually referenced, not referred to a generic group of equipment. E.g. do not use Start all lime sludge pumps. Instead, use Start : 1234PU Lime Sludge Pump 1, 1235PU Lime Sludge Pump 2, 1236PU Lime Sludge Pump 3, 1237PU Lime Sludge Pump 4 and 1238PU Lime Sludge Pump 5. Each automatic sequence shall be documented at the appropriate Level : Level 3 (System) where complex system wide sequences control multiple items/loops. Level 4 (Instrument Loop/Equipment Items) where a sequence involves a small number of items/loops that work to support a primary item of equipment. Eg. A pump and its related control valve. The recommended sequence step layout uses a Major step and minor step as follows: Step 0.00 may be used when the Mode is not active. Permissives should start at Each separate cycle within each mode should start at 1.01, 2.01, 3.01, etc. The sub-step (i.e. a, b, c, etc) is not part of the sequence, but is used to assist in reading of this document. It is only used on a step with many conditions. MODE 1 SEQUENCES Mode 1 permissives Step description Step description: a. Sub-step description, and b. Sub-step description, and c.

The majority of sequences occur at either an equipment or system level, however in some instances a sequence may exist at a process or site level (eg. plant start-up or shutdown sequences) and should be documented at the appropriate level (i.e. Level 1 or 2). Where there are multiple Automatic sequences for a particular system (eg. Filter DAF sequence, Filter Backwash Sequence), each shall be clearly distinguished through the use of a unique title and description (refer template) Hard-wired interlocks: Define all process related hard-wired interlocks. Refer Attachment A for examples Software interlocks: Define all software interlocks. Refer Attachment A for examples Parameters, Alarms and Trends: Define any parameters, alarms and trends in tabular format with the default values that shall be used on the first PLC scan. Where applicable, Standard alarms are to be provided for Loops, Drives and Valves. The tables below shall be used in the functional specification and shall not be modified unless ActewAGL gives approval. All rows that are not applicable to the particular item shall be deleted. Refer to Attachment A for worked examples. An introductory sentence may be provided to outline non-standard, relevant information, further to that contained within the table. Refer to Attachment A for worked examples. 4 Apr of 43

19 Definition of Alarms Alarms shall be given one of five categories: 1. High (H) - alarms that need immediate attention. 2. Medium (M) - alarms that may interfere with the normal operation of the plant. 3. Low (L) - alarms that are of low importance and do not interfere with the running of the plant. 4. Events (E) - alarms that are not displayed on the alarms page. They appear on the summary page only. Includes events such as pumps starting and stopping. 5. Off-Normal (O) - alarms that are not displayed on the alarms page. They appear on the off-normal alarms page only. Off-normal alarms are for equipment that is not in the normal operating mode Field inputs Define whether field inputs (inputs that are physically wired to the PLC) that generate an alarm, deliver an active high or active low signal. Typically, most inputs are active high, i.e. a signal is received when the condition is true, e.g. the PLC receives a signal when the pump is running. However, some inputs are wired using a fail-safe method (active low), i.e. a signal is absent when the condition is true, e.g. the PLC loses a signal when an intruder is detected. This method provides additional signal reliability by attracting attention to an input failure, possibly caused by several factors, including; signal power failure, rodent interference or poor wiring. This information is only required for alarms based on direct field inputs, and may be left blank for all other alarms that are internally generated within the PLC Alarm Triggers An alarm may be generated when a Variable becomes either:, False or some other additional condition/s. The alarm may also have a delay before it is generated. Level 3 (System) Parameters 4 Apr of 43
