42AVEVA World Magazine 2013|Issue 1Opening the CatalogueA look under the covers of the recently released AVEVA Catalogue ManagerTManaging all the resources required to build even a modest-sized plant is a complex task involving large amounts of information, which is why AVEVA Enterprise Resource ManagementT (AVEVA ERMT) was created. In December 2012, AVEVAT announced an important addition to the new family: AVEVA Catalogue Manager. This performs the essential function of ensuring that material definitions are centrally managed and complete, and that they comply with appropriate standards and naming conventions, and remain synchronised with the evolving engineering design.Material catalogue information is a foundation for efficient projects and is used by every engineering discipline. Polluted information hinders project start-up and can lead to costly errors and delays, so here we will examine some of the fundamental principles embodied in AVEVA Catalogue Manager.The need for consistencyCatalogue pollution commonly arises through duplicate coding or inconsistent descriptions being created under the pressures of project timescales. It is easy to illustrate the problem by considering, for example, the following definition of an armoured electrical power cable:11kV-XLPE-Plain Cu-SM&PCT-SWA-PETP-ZHLS-Binding Tape.Here we have eight separate properties of the cable, succinctly describing the rated voltage and the various materials used in its manufacture; each property corresponds to an 'attribute' of the cable. An experienced electrical engineer might not be confused by these properties being misspelt, or appearing in a different order, but every time information has to be reinterpreted or queried by anyone, valuable time can be wasted and errors can arise. The same situation applies to almost every category of materials. Clearly, being able to map properties against attributes helps us to reliably understand the material being defined. In the case of the cable example, the property sequence tells us that this particular cable has the following attributes:z Rated voltage: 11kVz Insulation: Cross-Linked Polyethylene (XLPE)z Conductor: Plain Copper (Plain Cu)z Screening: Semi-Conducting Material and Plain Copper Tape (SM&PCT)z Armour: Steel Wire Armour (SWA)z Filler: Polyethylene Terephthalate (PETP)z Bedding: Zero Halogen Low Smoke (ZHLS)z Separator: Binding TapeDescribing a component clearly and consistently is a fundamental requirement; it reduces the number of material identification problems and the valuable time and effort wasted resolving these with suppliers, or at the job site. In practice, during the purchasing phase, these abbreviated engineering descriptions are often replaced with equally consistent but longer and more immediately understandable procurement descriptions.An example of how a logically structured definition of a pipe can be automatically converted into a code and both a short and a long description.Component typeAttributesAttribute valuesCodingDescriptionsJohn AllenProduct Manager, Enterprise Resource Management, AVEVA
AVEVA World Magazine 2013|Issue 143AVEVA Catalogue Manager ensures this consistency of information by providing a highly configurable classification structure. This structure can be configured by the engineering contractor to match the structure used by its client. For example, cables can be classified, first by rated voltage range, then by whether they are armoured or unarmoured; each class identifies a consistent set of attributes. This makes it easy to select materials of a particular type, to automatically generate a commodity code (identifying a family of components) or a number of configurable descriptions. This rigorous process applies consistency to all the engineering and design tasks which use materials information. Automating the processIn use, AVEVA Catalogue Manager enables an engineer to generate a material code in the accepted format by successively selecting from attribute lists for a specified component class. This automatically validates the integrity of each choice, while populating the corresponding part of the code and its descriptions.Particularly for the piping discipline, there can be thousands of such codes and, in practice, it would be very laborious to define manually every type and size of piping component. AVEVA Catalogue Manager can substantially automate this process by extracting the relevant information from existing piping specification documents and intelligently creating both the specification detail and the catalogue at the same time, in imperial or metric units.Information templates for speed and accuracyAt the start of a project, piping specification detail is a key enabler. Rapid generation of piping specification content is achieved by using templates, speeding up the identification of component attributes, allowing rapid completion of the detail needed for the specification and, if necessary, generating new components and descriptions. Branch table templates, in particular, provide a rapid, graphical way of entering data, and use colour coding to highlight potential inconsistencies, enabling an engineer to resolve a problem more easily. This process will generate just the particular component specifications required for the project in hand.AVEVA PDMST attributes can also be added automatically and then adjusted to the specific needs of the project specification. Once a complete specification has been approved, it becomes available to both PDMS for 3D design and AVEVA MaterialT for procurement and scheduling. This ensures the vital synchronisation of material identification for specifications and provides confidence in subsequent Bill of Material transfers.Specification changes are fully controlled, while data integration ensures that an approved change is highlighted both in PDMS (or AVEVA Everything3DT) and in the Materials Management solution. Ensuring such reliable exchange of catalogue information between applications is a key enabler for a successful project.A logical first stepAVEVA Catalogue Manager is an integrated part of AVEVA ERM, but it can also be used independently of AVEVA Material. This enables a customer to deploy an enterprise-wide resource management solution in a progressive manner, consolidating benefits at every stage. Catalogue Manager is a logical first step, as it can aggregate existing legacy data into a trustworthy resource that can support multiple projects and future ERM extension. Catalogue Manager can also be used to share information with other applications, such as third-party materials management or design systems.More information about AVEVA Catalogue Manager, or the complete AVEVA Enterprise Resource Management solution, is available at www.aveva.com/aveva_erm.AVEVA Catalogue Manager enables the consistent and accurate generation of complete catalogue and specification data.Using graphical branch table templates, AVEVA Catalogue Manager enables the rapid specification of accurate piping specification content.
