Libs/Main

The library was created to provide main templates of the DAQ-sources processing and related services.

The template's names and their parameters are available in languages: English, Ukrainian and mRussian. Their source code wrote in the 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.

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

• supplied with a ready and proper package of the Linux distribution like to "openscada-libdb-main", "openscada-LibDB.Main";
• directly taken for most actual one from the subversion repository and converted to the DB SQLite file in the way:

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

• downloaded for the one attached here.

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.

For the DAQ-templates at generic you need create a device representing object into the Logical Level module and select proper template from the templates library. Next, to correct configuration, follow to specific of the template into the individual description.

1 Templates of standard structures of the DAQ-parameters

Common, representative and unified template of analog input signals processing. The template forms a structure of analog parameter (complex tag) which can be easily connected to most widgets and cadres of the main elements library of the user interface just pointing the parameter object.

The representative structure of analog parameters (complex tags) is:

• "Variable (var)" — end variable of the parameter — engineeric real value, allowed and suitable for archiving.
• "Error (err)" — obligatory attribute of any parameter, consist of the combination of the error code and short text description, like to "2:No data or connection with source". The template reserves next error codes:
  • 1, 2 — hardware errors, when the data mostly wrong;
  • 3, 4 — alarm border errors;
  • 5, 6 — warning border errors;
  • 7 — the speed error of the variable changing.
• "Violations suppress (alSup) and delay (alDelay)" — violations generic control for suppressing and delaying.
• "Scale: minimum (min)" and "Scale: maximum (max)" — main scale of the end variable, the output of which causes a hardware border error. The scale is also used as a scale of the variable trend display on the graphs.
• "Logarithmic scale (log)" — the scale sign of the variable trend display on the graphs in the logarithmic scale.
• "Dimension (ed)" — dimension (unit of measurement) of the variable.
• "Precision (prec)" — number signs after the dot, for positive values, and precision (signs in whole), for negative ones, to display the real end variable on the screen.

Template IOs

Configuring and using

1. Create and start a logical controller object or use any presented one with the needed scheduling properties.

2. Create a logical parameter object and select this template for it. Enable the parameter.

3. Into the tab "Template configuration" of the logical parameter object you need to set:

• Input — link to a source of the "raw" signal.
• Input processing procedure — form for the complex preprocessing and complete generation of the analog input on the internal programming language of OpenSCADA. It is optional and should be defined in complex cases, for example:

• simple and transparent preprocessing to bring the percentage of UPS load to power that can be done with iMult also:

in = 490*in/100;	//the UPS has 480W

• implementing of the input signal counter — consumed electricity of the UPS:

//Checking for the data validity
if(ctx.cntr.isEVal())	ctx.cntr = this.var.get();
if(!in.isEVal()) {
	pUPS = 33;
	if(ctx.cntr.isEVal())	ctx.cntr = (pUPS+in)/(3600*f_frq);
	else ctx.cntr += (pUPS+in)/(3600*f_frq);
}

//Checking for the next month reset
month = 0; SYS.localtime(SYS.time(), 0, 0, 0, 0, month);
if(!ctx.month.isEVal() && month != ctx.month)	ctx.cntr = 0;
ctx.month = month;

in = ctx.cntr;

• generating of the extended violations — processing for the external signals related to the source:

gO = this.cntr().prm_grps;
if(SYS.DAQ.JavaLikeCalc.lib_aviary.sensorError(gO.prm_generic.PRG_Input_Err_T_room_S.get(),levErr,tErr));
else if(!(tVl=gO.prm_alarms.PRG_Alarm_T_max.get()).isEVal() && tVl)
	levErr = -4, tErr = "11:above the set limit";
else if(!(tVl=gO.prm_alarms.PRG_Alarm_T_min.get()).isEVal() && tVl)
	levErr = -4, tErr = "11:below the set limit";

• Minimum and maximum of the module scale — must be set at the case of significant difference the hardware and the generic scales, for example:

• the input is raw and measured in value of the current [4...20]mA, here it is necessary to specify 4 and 20 mA;
• the previous case where it is necessary to simply and transparently calibrate the end value — with a precision device set 4mA and 20mA and indicate here the real measured values of the "raw" signal.

• Input addition and multiplication — use for easy and linear correction of the input, for example:

• calibration for the end value, which is less transparent and these coefficients should be calculated according to the formulas:

iAdd = ((plcMin*precMeasMax)/plcMax - precMeasMin)*(plcMax/(plcMax-plcMin))

iMult = (plcMax - plcMin) / (precMeasMax - precMeasMin)

• Allowed scale exceeding — set if necessary to exceed the value of the main border, and when this scale starts to perform the recommendation function, say for the initial display of the trend on this scale.
• PLC imitation and the imitation input — define at the need to simulate the input as required in the functions.

4. RESULT: Launching the controller object (where this parameter is created) and if it has not been started, we must get the operational data in the tab "Attributes" for: variable, error status; and the generation of violations if the state of the error is nonzero.

5. In the process of the working, through the tab "Attributes" of operational data, in addition to obtaining the result, it is possible to perform operative setup and control on:

• Scale: minimum and maximum — strictly set to the range of data changes by availability and according to the hardware border, otherwise the value will be distorted! In the absence of the hardware border, this, the main border, is arbitrary and advisory, although exceeding of the border by the value will be also accompanied by a violation.
• Scale: square — set if the hardware border is square one.
• Filter time — set the filtering time for noisy signals.
• Substitute: mode and variable — set the desired substitution mode at invalidity the variable.
• Violations suppress — set at the need of the parameter violations complete suppression — to disable their generation in whole.
• Violations delay — set the delay time for the generation of the violations, to exclude frequent generation, characteristic to uncertain sources of data, characterized by short-term loss of communication.
• Border up/down alarm/warning — set when it is necessary to generate violations at the exceeding of the alarm/warning borders.
• Hysteresis of borders violation — set the hysteresis of removing the violation, that is, removal of the violations occurs at the specified percentage later, in order to prevent the frequent generation by fluctuating the value near the border.
• Motion speed — set if it is necessary to warn about fast change of value.
• Name, Description, Dimension, Precision, Logarithmic scale — set this information as needed when displayed, or as an element of the passport.

• exceeding the input value of the hardware border — error code 1,2 and alarm level 5;
• exceeding the end variable of the alarm border [aMin...aMax] — error code 3,4 and alarm level 4;

Disabled at setting for equal or inverted values of the border

• exceeding the end variable of the warning border [wMin...wMax] — error code 5,6 and alarm level 2;

Disabled at setting for equal or inverted values of the border

Template IOs

Configuring and using

1. Create and start a logical controller object or use any presented one with the needed scheduling properties.

2. Create a logical parameter object and select this template for it. Enable the parameter.

3. Into the tab "Template configuration" of the logical parameter object you need to set:

• Input — link to a source of the "raw" analog signal.
• Setpoint, Manual input, Output, Mode: automate, Mode: cascade, Scale: minimum, Scale: maximum, Gain, Ti, Gain differential, Td, T differential lag, Insensitivity, Upper output border, Lower output border, Coefficient of input 1, Coefficient of input 2, Coefficient of input 3, Coefficient of input 4 — link to a source of the PID-regulator.
• Input addition and multiplication — use for easy and linear correction of the input, for example see the template "Analog signal, unified".
• Allowed scale exceeding — set if necessary to exceed the value of the main border, and when this scale starts to perform the recommendation function, say for the initial display of the trend on this scale.
• PLC imitation and the imitation input — define at the need to simulate the input as required in the functions.

4. RESULT: Launching the controller object (where this parameter is created) and if it has not been started, we must get the operational data in the tab "Attributes" for: variable, error status; and the generation of violations if the state of the error is nonzero. Also we will get all the PID-specific attributes.

5. In the process of the working, through the tab "Attributes" of operational data, in addition to obtaining the result, it is possible to perform operative setup and control on:

• Scale: minimum and maximum — strictly set to the range of data changes by availability and according to the hardware border, otherwise the value will be distorted!
• Scale: square — set if the hardware border is square one.
• Filter time — set the filtering time for noisy signals.
• Violations suppress — set at the need of the parameter violations complete suppression — to disable their generation in whole.
• Violations delay — set the delay time for the generation of the violations, to exclude frequent generation, characteristic to uncertain sources of data, characterized by short-term loss of communication.
• Border up/down alarm/warning — set when it is necessary to generate violations at the exceeding of the alarm/warning borders.
• Hysteresis of borders violation — set the hysteresis of removing the violation, that is, removal of the violations occurs at the specified percentage later, in order to prevent the frequent generation by fluctuating the value near the border.
• Motion speed — set if it is necessary to warn about fast change of value.
• Name, Description, Dimension, Precision, Logarithmic scale — set this information as needed when displayed, or as an element of the passport.

Common, representative and unified template of an interface to the Proportional Integral Differential (PID) regulator based on the common analog input signal but with the PWM-output, extended by binary states of indication the violations and mostly like to the template "PID signal, unified, violation statuses". The template forms a structure of the impulse PID-regulator which can be easily connected to some cadres of the main elements library of the user interface just pointing the parameter object.

The representative structure of the impulse PID-regulators is mostly equal to the template "PID signal, unified, violation statuses" and contains a number of attributes specific to the pulse output and the attribute of determining the operation of this regulator in the analog mode, that is, this template is even more generalizable:

• "Impulse output up (impQup)" and "Impulse output down (impQdwn)" — signals of the PWM-output.
• "Mode: analog (analog)" — a sign of working the regulator in the analog output mode.

Functions
Mostly the same as the basic template "PID signal, unified, violation statuses" and the impulse-specific attributes are additionally provided: "Impulse output up", "Impulse output down", "Mode: analog", "T impulses period", "T minimal impulse", "Impulse rate factor".

2 Templates of the complex objects

In some cases where an object is only a part of a common automated system and does not require deep detailing to the level of signals and parameters (complex tag) around them, including without the need for archiving, it is convenient to unify them in one representative object of the data source OpenSCADA with appropriate consolidated view and object control as a set of simple attributes with violation elements. Such consolidation often occurs around specialised data sources, whose access to data is usually implemented through a separate exchanging protocol, but without unifying the transmission of this data to the level of visualisation and signalling by a separate attribute of the object.

In general, the representative structure of a complex object is:

• "All items (items)" — common object-type attribute where the attributes of a physical object are directly described by object-type attributes in items and with defined descriptive attributes in each
  • id — attribute identifier;
  • descr — text description of the attribute;
  • wr — a sign of the possibility of writing or a list of value variants to their selection, through the symbol ';';
  • alarm — violation code:
    • 0 — no violation — "NORM";
    • 1 — violation level "WARNING";
    • 2 — violation level "ALARM";
  • val — attribute value;
  • set — attribute value to set the attributes accessible to write.
• "Error (err)" — obligatory attribute of common violation status of the object in general, consist of the combination of the error code and short text description, like to "2:No data or connection with source". The template reserves next error codes:
  • 1 — violation level "WARNING";
  • 2 — violation level "ALARM";
  • 3 — unreliability or lack of data.
• "Violations suppress (alSup) and delay (alDelay)" — violations generic control for suppressing and delaying.

Generally, it is advisable to create such template (a layer above the physical data source object) above a raw data source that provides this data in attributes and without processing, and this template therefore performs:

• collection of these attributes of the raw source into items;
• processing of properties of the attributes;
• control and transmitting of commands of the values setting;
• processing of the violation conditions at single attributes and at the object in whole, together with which these violations can be fixed in the table of actual violations, typically by the alarmSet() function.

In addition to complex object templates, this object-control mechanism can be implemented by templates for implementing the logical level of data access, such as in IEC60870.

To represent the data of the object-control mechanism, there currently provided the appropriate Object properties frame, which provides these properties as a table-list with illumination of the violations and the possibility to change the selected and accessible to edit row-properties.

The template of processing input initiative connections was created to provide the last link of implementation and support for conception of data acquisition in the passive mode and the initiative connection, that is — the control of associative connections, created by the input transport at each connection.

After implementation this control together the new common-unified output transport connection function outAt() that template became deprecated for sources adapted to use the new mechanism, but you still can use the template for not adapted sources.

The function of creation associated output transports at connections is currently only supported by the module "Sockets" and for TCP-sockets.

• Total complexity: 0.9 HD^[!]
• Sponsored by, for whole complexity: Elyor Turaboev, BLUE STAR GROUP Ltd

The control of associated transport means:

• obtaining a list of the associated transports, by the function assignTrsList() of the input transports;
• reading from new transports (opened) of identification information, which currently represents only the source object identifier;
  • search, by the received identifier, the source object and assigning to it of this transport;
  • registering in the attribute "prcTr" of the object type.
• checking of existing transports for their closure (detachment), for which performed the deregistration in the attribute "prcTr" of the object type and the establishment of the source object in the empty value; disconnected output associated transports are reused by the input one upon receiving a new connection then it is switched on.

The template can control the containers of data source objects, constructed both as DAQ-objects of the controllers and logical level parameters, what representing the data source and having a transport address definition field, and what generally defined by the configuration field "srcObjPath" of the format {CntrAddr}:{TrCntrFldAddr}, where:

• CntrAddr — container address, for example: "ModBus" — for DAQ-objects of the controllers, "LogicLev.CntrPLC" — for logical level parameters;
• TrCntrFldAddr — address of the transport control field in the source object, for example — "%2fcntr%2fcfg%2fADDR" for "ModBus"; what can be obtained in a configurator at the history of pointing on the control field in the status line.

Template IOs

Configuring and using

1. Create an input transport of receiving the initiative connections of the module "Sockets" with the name like to "InitiateCons".

2. Set the previously created transport to the needed address of opening the input socket and move it to the mode of creating the associative output transports, leaving the protocol field in empty.

3. Provide a container of the data sources to which associative transports must be connected, which can be either a DAQ-module (such as "DAQ.ModBus"), or a logical controller (such as "DAQ.LogicLev.Sources"), or a parameter in it (such as "DAQ.LogicLev.PLC.Sources"), with logical level parameters representing the data source.

4. For this template create and run a logical controller object or use any available with the required scheduling properties.

5. Create a logical parameter object and select this template for it. Enable the parameter.

6. In the tab "Template configuration" of the logical parameter object you need to set:

• Input transport — to value of the identifier of the input transport, created in the item 1, like to "InitiateCons;
• Output transport timeouts — increase the first digit for very slow connections and typical is normal in most situations
• Source objects path — set according to the item 3, for the first part, and to the control field path, for the second part, for example, and typically for for "ModBus", is — "ModBus:%2fcntr%2fcfg%2fADDR".

6. RESULT: Starting the controller object (where this parameter was created) and when it was not started, we should get, in the attribute prcTr of the parameter for information about the processed and therefore successfully transport-linked data sources. In case of some violations, we will get the corresponding information in the attribute err of the parameter. The absence of a representative object for the received identifier is placed in the protocol of messages.

The template of acquiring weather data from different weather services in Internet and initially it is only Open Weather.

The weather data divided on current and forecast with their placing in corresponded objects, where current attributes placed directly in the root and forecast days (the "day" object) and times (the "time" object) inwardly corresponded day according to the current timezone. These data acquired at specified schedule independently for current and forecast, and by default the current ones are performed per hour when forecast ones per day. The data can be accessible by user both as directly and through a specially created widget of the main library.

Template IOs

Configuring and using

1. For this template create and run a logical controller object or use any available with the required scheduling properties.

• Scheduling at CRON of forecast update — to value of need scheduling for forecast data acquiring in the CRON format, at empty the acquiring will be performed with period of execution the controller object.

4. RESULT: Starting the controller object (where this parameter was created) and when it was not started, we should get the weather data in the attribute Current (current) and Forecast (forecast) and after setting your city code in the corresponded attribute. City code you can obtain from the official site in the URL after searching your city in the site form.

4 For WebUser

The template for implementing a HTTP File Server directly in OpenSCADA, which is suitable one at missing a full-featured one for functions of servicing file requests from OpenSCADA Web-interfaces.

Currently there implemented only requesting files by the GET request of HTTP. There are supported also the Partial Content requests in single range and with forcing to this mode at some configured file size. That is work properly only for video and audio files and doesn't work for other files especially documents, so you have to configure the file size limit for solid reading in maximum size of your documents. For proper working the Partial Content requests we need to implement the HTTP request HEAD in the module Protocol.HTTP before implementing here!

Template IOs

Configuring and using

1. Create a page in the UI.WebUser module with some reasonable PageId.

2. In the tab "Procedure" you need to set:

• Base directory from which the page'll search files.
• File size limit for solid reading, else enables the partial content.

3. RESULT: Opening URL "http://{OpenSCADAHost}/WebUser/{PageId}/{MyFile}" in a WebBrowser will open and send you file on FS "{baseD}/{MyFile}".
