OscadaLibs.db (SQL, GZip) > DAQ.JavaLikeCalc.doc
vcaBase.db (SQL, GZip) > VCA.wlb_doc

en, uk, ru Roman Savochenko LibDocuments.png Provides the combined library of the reports, documents and related functions of common and the industrial automation.
- expand the document "Year report of the month values" in processing the manual entered counters overrun;
- expand the document function "Diagram" in support the bar graphs.

The library is created to provide report and document elements-frames of the user interface and it contains graphic elements, often need when forming the user interface of the automation of technological and common processes. The library is mostly built on the basis the primitive "Document" and the internal programming language JavaLikeCalc, for the related functions also.

The element's names and their parameters are available in languages: English, Ukrainian and mRussian. Their source code wrote in human-language independent mode with calls for the translations by the function tr() and the message's translation also allowed for English, Ukrainian and mRussian.

Contents

1 Documents

Contains elements-frames of the documents of the template and end types, what intended to be placed in the "Documents" part (the type of view) of the project tree of the pages, built on the concept of the signal objects of the root page "RootPgSo". However, they may be located as separate entities or as a part of your own concept of the page management, but it should be take in account that frames often refer and call the panel of documents!

For connection the library part to a project of the OpenSCADA station you can obtain the database file as:

wget http://oscada.org/svn/trunk/OpenSCADA/data/LibsDB/vcaBase.sql
sqlite3 -init vcaBase.sql vcaBase.db .exit

This obtained file next you can place into the project directory of the station and create the database object for the DB module "SQLite", registering the database file in the configuration.


1.1 Document - archival (doc)

1.2 GPLv2 * en, uk, ru Roman Savochenko

The frame, shown in Figure 1.1, is a template of documents of the archive type and it is provided as an example and for building own archive documents on it basis. The main specific of that document type is the periodic generating on the VCA-session level (in the background) and placing the final and ready to view documents to an archive, the VCA-project's session DB-table "prj_{ProjID}_ses".

The main advantage of this document type is the lowest load on CPU during the generation, which can be multi-step one during the main generation period, and the fast view, which involves simply opening the ready documents from the archive. But this document type has a significant disadvantage, which is the constant execution of single project session in the background and the absence of which leads to the omission of the documents generation in the archive.

At.png Therefore, documents of this type are appropriated to use on the stationary AWPs of the operators, even if it is a reproduction from the visualisation server, and are useless in the WEB-interface!

Fig.1.1. The "Document - archival" frame in the development mode.

Using — development
The frame can only be used as a basis for creating your own archival type documents, for which you should it copy or inherit, by selecting the appropriate option in the copy dialog. Next, you need to edit the document template, in the appropriate attribute, according to the needs of your document, and write your own procedure for periodically and step-by-step formatting of the documents with closing to the archive, a sample of which can be obtained from the final documents based on this.


1.1.1 Day report of the hour-averaged values (docRepDay)

3.2 GPLv2 * en, uk, ru Roman Savochenko -1 ms (parent)

The document, shown in Figure 1.1.1, is provided for generating a day report of the hour-averaged values in view of the trends diagram and the data table. The document is initially the archival type but in time it is made dynamic also, so, depending from the execution mode, you can whether select a ready document from the archive or specify the data time and depth. The document commonly uses and represents the representative structure of the DAQ-template "Analog signal". As a data source of this document is the value archives of the DAQ-parameters.

Working in the primary archival mode performed with the 5 minutes period, when during an hour an one record-row data is formed. The last one record-row is closed at the 5 minute of a new hour (14:05 for example) and a new one record-row is started. Whole and complete document is archived at the 3 minute of the "Report hour (repHour)" of the next day (09:03 for example).

1.2.6 Year report of the month values (docRepYear)

1.3 GPLv2 * en, uk, ru Roman Savochenko -2 ms (disabled)

The document, shown in Figure 1.2.6, is provided for generating a year report of the month values in view of the trends diagram and the data table. The document is the dynamic type. The document commonly uses and represents the representative structure of the DAQ-template "Analog signal". As a data source of this document is the value archives of the DAQ-parameters mostly.

The document first introduced the manual entry of archival values of a large measurement time interval, which in this case is a month, as an undetermined interval. This feature is of great relevance for counters that for one reason or another cannot be connected to the system directly, with continuous measurement or periodic uploading of archive parts. Determining the parameter to manual input performs by setting the constant isMan of the appropriate parameter, which enables the form elements at the top of the document under the appropriate rights ("root" or in the "ITW" group), and accessing the data for the table and trend strictly at the interval of the document — month, as well as entering them.

Manually entered data is stored whether traditionally in an archive of values, with only one value recorded per representative interval, that is, with unreliable values between them; or as a separate entry with a value in the message archive, also introduced for the first time by this document:

CATEGORY: defines the source ID SrcID in the form "val{SrcID}", where:
  • "val*" — the typical template-sign of a value, that can be directly used in the category filter to determine only the values in messages;
  • SrcID — source identifier, what directly entered by a constant in the parameter address var.
TEXT: the parameter Name and Value in the form "{Name}: {Value}".

The message archiver of the module FSArch must be set for the next attributes to correct work perform together this document: set "Prevent duplicates", "Consider duplicates and prevent, for equal time, category, level" and set "Time size of the archive files" to 3660 days. The module DBArch must work without such kind specific.

2 Service related functions

The service functions of the frames of reports and documents are intended to perform the characteristic tasks of obtaining reporting data, for which you need to perform some verification or counting, for example, to check the validity and to summarize. Forming complex data, such as charts embedded in a document, can also be a service function.

To address the library functions you can use the static call address DAQ.JavaLikeCalc.lib_doc.{Func}() or dynamic SYS.DAQ.JavaLikeCalc["lib_doc"]["{Func}"].call(), SYS.DAQ.JavaLikeCalc["lib_doc"].{Func}()". Where {Func} — function identifier in the library.

For connection the library part to a project of the OpenSCADA station you can obtain the database file as:

wget http://oscada.org/svn/trunk/OpenSCADA/data/LibsDB/OscadaLibs.sql
sqlite3 -init OscadaLibs.sql OscadaLibs.db .exit

This obtained file next you can place into the project directory of the station and create the database object for the DB module "SQLite", registering the database file in the configuration.


2.1 Getting value from the value archive (getVal)

1.1 GPLv2 * en, uk, ru Roman Savochenko

Query the value for the specified time (time:uTime) from the assigned archiver archtor (FSArch.1m) and issuing results with the specified number of digits prec after the dot.

The function works with the DAQ-parameter attribute objects to which the archive is attached and the address addr is written to it in full path, like "/DAQ/LogicLev/gen/prm_F3/a_var". For the empty archtor, the request will be made generally to everyone with the archive buffer periodicity!

In the process of obtaining a value, the time of this value may be different from the requested one, if the archive is not currently present and returns the closest value, preventing why you may by setting strong. When you need to get the closest valid value in a controlled way, for counters to example, you have the "tryTo" time argument to which to look for the closest valid value. The time in tryTo may be both lesser and bigger than the request time.

Initially, the result is presented as a string of real value with a certain number of digits prec after the dot, and with the value "Empty" for not valid values, allowing it to be inserted into the document without further processing. However, at requiring of additional processing and specific formatting, the result can be obtained with an unformatted real value, for prec less than 0.

Parameters

Identifier Parameter Type Mode Hidden Default
rez Result String Return false
addr Address String Input false
time Time, seconds Integer Input false
uTime Time, microseconds Integer Input false
prec Signs after dot Integer Input false 3

2.2 Average value of the value archive (averVal)

1.1 GPLv2 * en, uk, ru Roman Savochenko

Calculate the average value over a specified period of the time [bTime...eTime], for the archiver archtor (FSArch.1m) data and issuing results with the specified number of digits prec after the dot.

The function works with the DAQ-parameter attribute objects to which the archive is attached and the address addr is written to it in full path, like "/DAQ/LogicLev/gen/prm_F3/a_var". For the empty archtor, the request will be made generally to everyone with the archive buffer periodicity!

In the process of calculation, the data in the archive is checked for validity and the value of the percentage of reliable data actPerc that participated in the result is formed. In general, you should use intermediate archivers — medium quality archivers, so that there is not too much data in a given interval to reduce performance, and that it does not have one value at all.

Initially, the result is presented as a string of real value with a certain number of digits prec after the dot, and with the value "Empty" for not valid values, allowing it to be inserted into the document without further processing. However, at requiring of additional processing and specific formatting, the result can be obtained with an unformatted real value, for prec less than 0.

Parameters

2.4 Diagram (diagram)

1.4 GPLv2 * en, uk, ru Roman Savochenko

Building trends diagram to SVG, which may be builtin next to the XHTML-document, for specified period of the time [(end-size)...end] and from the sources srcs.

The diagram forming code is based on code of the primitive "Diagram" of the visualisers, and which was quite simply migrated from C++ to the JavaLikeCalc embedded language. Currently, only trends have been moved-implemented!

The appearance of the diagram is determined by its dimensions hsz*vsz and the source SVG-template tmpl, a number attributes of the root tag of which has special meaning and corresponding to the primitive "Diagram":

Currently, only value archives can be used as a data source, either directly to them or through the DAQ-parameter attribute with the archive. The number of data sources is not directly limited and is written in separate lines of the argument srcs in the format "{addr}:{min}:{max}:{color}[:{scale}[:{width}]]", where:
