The previous official version of the Reliance SCADA/HMI system (version 4.7.1) was released on May 20, 2015. After almost a year, Reliance 4.7.2 is out with some new features and enhancements. The major changes are summarized below.
The Reliance system has been tested and is fully supported on Windows 10. This means that, beginning with Windows XP, all Windows versions are supported.
Reliance is a 32-bit program. Standard programs designed for the 32-bit version of Windows cannot handle addresses larger than 2 GB of RAM. Reliance 4.7.2 can handle addresses up to 4 GB of RAM when run on the 64-bit version of Windows. See LARGEADDRESSAWARE.
In Reliance 4.7.2, we have improved the way some files are stored on disk. Now, the number of writes is minimized. We have also added detecting an SSD at project startup. More details can be found in this technical article.
The system of access rights has been revised. Compared to Reliance's previous versions, the number of access rights is no longer limited to 30. It is now unlimited.
In previous releases, alarms/events were displayed in different colors depending on the alarms' status (red, yellow, white). You can now configure colors in order for alarms/events to be displayed according to their status and/or type. This can make the orientation in the alarm/event viewer much easier.

The Chart type property can now be configured at the level of trend series. This means you can combine, for example, a line chart and a bar chart in a single trend.

The list of special internal tags, which was introduced in version 4.7.1, now has the following new data types:
Special internal tags
Performing bitwise operations directly in VBScript was neither easy nor fast and, what is more, could lead to hazardous conditions. As a result, the following functions have been introduced:
These functions perform bitwise operations natively.
Another new function – RSys.ExecAction – allows performing a predefined action directly from scripts. The RSys.ExecActionAndWait function performs an action and waits for its completion (e.g., when it is necessary to wait until
a dialog box is confirmed).
The RSys.ExecApp function, which is intended to run an external application from a script, has been available for a long time. If you, however, need to run an external application from a script and wait for its completion, you can now simply use a new function named RSys.ExecAppAndWait.
New objects named RConst and RProj and new methods named RProj.GetObject and RProj.GetObjectList have been added to the Script Manager. They allow access to some properties of project-defined objects.
| Object type | Supported properties |
|---|---|
| All types | ObjectType, ID, Name, Alias, CompoundName, CompoundAlias, FullName, FullAlias, ExternalID, Comment, Description |
| Tags | Value, Quality, TimeStamp, LocalTimeStamp, IsQualityGood, EngUnits, EngName, CharacterCount, ElementCount, DecimalPlaceCount |
| Alarms/events | Text |
| Users | PhoneNumber, EmailAddress, Code |
| SQL connection | ConnectionString, DatabaseName |
For example, you can create a script that will retrieve the list of tags defined within a device (e.g., "BoilerRoom1"), loop through the list, and set the value of all tags whose names begin with, for example, "Param_" to, for example, 10. The functions are very general and, therefore, intended for widespread use.
In some cases, it is required to interconnect the Reliance 4 system and another information system to which project definition (i.e., the list of all objects, such as devices, tags, and alarms/events, with all their properties) is available. Therefore, the possibility to export the project to an SQL-based database so as to access the project in other information systems has been added to Reliance. If this option is active, the project is automatically exported at startup.

It may happen that your visualization project's windows will have to be converted to a different resolution. For this purpose,
a new wizard (Scale Windows and Components Wizard) is available in version 4.7.2. It allows you to proportionally change the size and properties of windows and components in a desired ratio (scale factor). The ratio can be entered either as resolutions (current and target) or as percentage.

The Combo Box component is usually used to select an item from the predefined list. Previously, the item list was always static. Beginning with version 4.7.2, it can be specified by a tag of type Array of String, so it can change during runtime as needed.

Window templates in a container and structured tags are a powerful tool for creating applications containing multiple instances of the same unit (group of objects). Up to version 4.7.1, it had been necessary to have a separate Container component for each pair window template–structured tag. Beginning with version 4.7.2, you need to have only one container with a window template and to dynamically control the container's link to a structured tag (using a string-type tag whose value controls the name of the structured tag). The template's contents can thus be changed during runtime by setting the name of the structured tag.

Reliance 4.7.2 has support for connecting to the Maatrix emergency communication service for the purpose of notifying users of alarms/events. For details, read this technical article.
A new method of project restoration – Restoration at end user – is now part of the Restore Project from Backup Wizard. This method is used in situations where a systems integrator is updating a project (at the end-user site) to which some changes have been made by the user (e.g., user passwords have been changed or new users have been added). If you choose this option, only files stored in the backup file will be restored except for the files defining users, trends, and reports.
Reliance 4.7.2 allows you to disable a number of confirmations so that they are no longer displayed.

If you wish to display them again, simply activate the Show option in the Environment Options dialog.

Reliance Smart Client now allows configuring trend properties. The settings are saved to a user profile on the server.

Beginning with version 4.7.2, it is possible to change the scale of visualization windows (zoom) even in the responsive mode. By long tapping on the touch screen within a visualization window, a slider for changing the scale appears.

The Pipe, Scale, Clock components and vector components are now displayed using inline SVG. This optimizes the amount of transferred data and there is no distortion when scaling.
