Corresponding DeltaV Implementation

A function that gets realized by technical functions of one or several units. Their realization may vary from unit to unit (for example, control of environmental conditions, such as tempering; blending the content by stirring; putting material in measured quantities in and out, such as dosing).

The lowest level of a procedural element in the procedural control model. It provides an interface to basic control. A series of steps that causes one or more equipment- or process-oriented actions. These actions issue commands to set or change controller constants, modes, or algorithms (for example, heat or drain).

The corresponding DeltaV term to the NE33 term basis function. When the phase class and its phase parameters are created, there are different ways to implement the potential various technical functions for this basis function in the DeltaV system (see technical function).

According to the process engineering interpretation, the term unit operation is used. It refers to typical material processing or transformations common to many productions (for example, dissolution, distillation, or certain reactions, such as hydration or sulphonation). If biological process engineering is included, basic biotechnical operations, such as fermentation, must be included as well.

According to control engineering interpretation, the term conduct operation is used. It signifies a reusable sequence of actions. For the production of different products applying similar production technologies (for example, similar processes, materials, reactions, risk potential, and so on), a number of conduct operations can be developed. A suitable combination of these conduct operations provides the required recipes for individual products.

A major processing activity that usually results in a chemical or physical change in the material being processed and that is defined without consideration of the actual target equipment configuration.

A procedural element defining an independent processing activity consisting of the algorithm necessary for the initiation, organization, and control of phases.

Written in the DeltaV system as Procedural Function Charts (PFC). Within an operation, phases execute sequentially and/or concurrently.

A source recipe scaled (for example, laboratory, pilot plant, large-scale plant) and adapted to a specific mode of operation (that is, continuous, batch). It contains all source recipe data (process stages, unit operations, material properties and ratios) as well as operating instructions for individual process stages. An operating instruction is an event controlled combination of actions. The actions are described by basis functions. A possible means of describing operating instructions is a functional diagram. In the case of discontinuous process stages, operating instructions may consist of individual conduct operations that are defined by means of basis functions.

A type of recipe that accounts for equipment capabilities and may include process cell-specific information.

Combined, these relate to the S88.01 master recipe definition and the NE33 basis recipe definition.

The extraction of data related to one or more batches is called a batch report. The extraction and ordering of the data in a report may vary based on the intended recipient of the batch report.

The recorded information pertaining to a batch.

The extraction of batch-related data in a predefined or user-defined format.

Basis function made production and process cell specific.

For this purpose a basis function is supplemented by data from the production order (that is, actual quantity data) and by the respective technical function of a chosen unit. Therefore, a control function serves to activate a technical function.

An NE33 control function is created in the DeltaV system at the time that an operator or a batch starts a phase on a unit.

Basis operation adapted to a specific production and process cell.

An operation that is part of equipment control

In control engineering applications, coded programs often provide technical functions. In this case the program is also referred to as a control phase.

A phase that is part of equipment control

This includes all information of the basis recipe, the basis function references in the functional diagram being replaced by the control function references.

The DeltaV software provides multiple algorithms types for control module logic. The algorithm types are Function Block Diagram, Sequential Function Chart, Command-driven and State-driven algorithms.

Several devices can be grouped to form an equipment module. This is useful if the devices are working together and are realizing one or several basis functions. Each device should be part of only one equipment module.

In the DeltaV software, it is the same as the S88.01 definition.

The DeltaV software provides multiple algorithms types for equipment module logic. The algorithm types are Function Block Diagram, Sequential Function Chart, Command-driven, State-driven, Phase Algorithm, Phase with command-driven run logic, and Phase with state-driven run logic.

Different alternative technical functions of the same equipment module are named modes of operation of the equipment module.

In S88.01, typically different modes of operation, such as heating and cooling on the equipment module (NE33) heating/cooling system, are realized as different phases.

The phase logic branches into the different modes of operation depending on the phase parameter value.

There are two different ways to implement the phase logic for the technical functions in the DeltaV system:

2. The phase logic of the phase class is used to write the control program for the phases. In this case, the differences in the equipment have to be covered either in the logic of the phase class directly or by using equipment modules with a unique interface to the phase but different logic that reflects the differences in the equipment.

To write the phase logic in a generic way, aliasing can be used in case of class-based phase logic. In case of the use of PLMs or equipment modules, the logic has to be written using dynamic references.
