Introduction Contemporary Controls BASview is a stand-alone, embedded, web-based graphical interface for building automation and process/access control systems. Multiple protocols are supported including LonWorks, Modbus/485, Modbus/TCP, BACnet/IP and BACnet MS/TP. Some of the features include animated graphic screens, scheduling, historical trending, runtime accumulation and alarm monitoring. All of these features are supported even with devices that do not natively support them.
Getting Started Login Screen By default, BASview uses a flash Interface — providing a rich user experience. Its login appears below. The default IP address of the BASview is 192.168.92.68, but yours may be set to a different address. You will be prompted to login. The default authentication strings are ... o Username: admin o Password: pass At the top of the login dialog you can find ...
Toolbar The 10 icons in the Toolbar are: Home Site Info Logout Users User Groups Admin Alarms Runtime Tree View Help Figure 3 — Admin Options The Admin icon (the wrench symbol) is a drop-down where you can see logs and status, configure the IP address, reboot the unit and update the firmware. If running 1.42d or later, any update file containing ".Firmware" somewhere in name can be used for the update.
IP Address Setting Enter your IP address settings — then reboot. In BACnet systems the Broadcast setting must match the broadcast address in your subnet. Figure 6 — Broadcast Setting in BACnet Systems Add a Driver To communicate with devices, you must load a driver. Right-click the Site icon in the Device Tree and select New Driver. In the popup, select the appropriate driver and press Ok.
Driver Configuration Enter in your driver configuration. For BACnet use a system-wide unique Device ID. The standard BACnet port number is 47808. Enter a label for the driver and press Finish. Figure 8 — Driver Configuration Add a Device to a Driver In the Device Tree, right-click a driver and select New Device. A Device Wizard appears so you can enter device parameters or, with BACnet, discover a device.
BACnet Device Scan If the NetworkID is 0, the device is on the same network as the BASview; otherwise it is accessed through a router. For each device you want in your Device Tree, select it, add a label then press the Add button.
Add BACnet Points Refresh the Device Tree to see your new BACnet devices. Right-click a device and select New Point. A Point Wizard appears Enter a point or discover points. Press Scan to discover points. Press Finish on next window. Figure 11 — BACnet Point Wizard Select points of interest and press the Add button. You can select multiple points. Points will disappear from the list as they are added.
Points To Be Written All points are read-only by default. To modify a point you must mark it writeable. Right-click the point and select Properties. When the Point Wizard appears, press Next. Press the Modifications tab (if displayed), check the “Allow this point to be manually changed by users” box and press Finish. Figure 13 — Allow a Point to Be Changed Manually Writing/Reading Points Left-click a writeable point in the Device Tree. A Point Information/Control popup appears.
Advanced Colours Advanced colours allow the colour and transparency of a component to change based on the value of the attached point. The component may also be set to flash to help draw attention to it. Use Advanced Colours This option must be selected to enable advanced colours. Conditions The list of conditions determines what the current settings for the component will be. Each condition will be tested, from the top of the list to the bottom of the list.
Alarm Wizard An Alarm is invoked by right-clicking a device driver in the Device Tree. It monitors a set of user-defined conditions and sends email notifications when the conditions are met. Once an alarm has been added to the tree, left-click it to edit the conditions. See Alarm Editor for more information. Alarms are also stored for later viewing using the Alarm Log. Settings Tab Label Label is the name of the item as displayed in the Device Tree.
Alarm Editor Left-click an alarm icon in the tree to edit alarm conditions, messages and email recipients. Status Tab The status tab contains: The current active/inactive status of the alarm. The date and time of the last change of state of the alarm. The last message generated by the alarm. A refresh button to update the status on the screen. A disable selection to completely disable the alarm. Conditions Tab This is where the alarm conditions are specified.
The comparison value can be any one of the following: Numerical Value — Type any valid numerical value. Another Point — Drag a point from the tree to compare with its current value. For digital and multi-state points, click the drop-down list to display the valid values. Value Range — For the in/out of range comparisons, type the low value and the high value separated by a comma (e.g.: 50,100). For the is/is not in list comparisons, type a list of values separated by commas (e.g.
Analog Point Wizard Below are the settings for points with a point type of analog. Analog Settings Tab Engineering Units The engineering units can be set to specify the units of measure or physical characteristics of the analog value. Common engineering units would include Degrees F, Amps and Volts. Type any text or select from a list of common units by clicking the down arrow to the right of the edit area. Precision Precision controls how the value is displayed.
BACnet MS/TP Device This screen is used to configure access to a single device on a BACnet/MS/TP network. Settings Tab Label Label is the name of the item as displayed in the Device Tree. All items in the Device Tree are sorted alphabetically by label. Folders can be used to organize items. MAC Address The MAC address of the device must be 0–127 and not match any other attached MS/TP device. Device ID The BACnet device ID of the device must be a unique number of 0–4,194,303. Max.
BACnet MS/TP Driver This screen is used to configure access to a BACnet MS/TP network. This driver is only used when connecting the BASview MS/TP module (BASV-MSTP) to the BASview. You can also communicate with MS/TP networks through a BACnet router (BASRT-B) — in which case you would communicate to these devices through the BASview BACnet/IP driver. Settings Tab Label Label is the name of the item as displayed in the Device Tree. All items in the Device Tree are sorted alphabetically by label.
BACnet Point Addressing BACnet point addressing is very simple for standard BACnet I/O points. Extended addressing is also available to access non-I/O or proprietary points.
Data Type The data type used for the objects listed above with property #85 (present value) is automatically known and used. If a property other than present value is used, or for any property of a proprietary object the default data type is "String". This will allow the value of the property to be viewed but will probably not be sufficient to write a new value to the property. Note that only NULL, boolean, character string and all of the numeric data types currently support writing.
BACnet/IP Device This screen is used to configure access to a single device on a BACnet/IP network. Settings Tab Label Label is the name of the item as displayed in the Device Tree. All items in the Device Tree are sorted alphabetically by label. Folders can be used to organize items. Address The IP address of the device or router (Example: 192.168.0.60). Do not include the UDP port. Device ID The BACnet device ID of the device must be a unique number or 0–4,194,303. Max.
BACnet/IP Driver This screen is used to configure access to a BACnet/IP network. Other BACnet networks, such as MSTP may also be accessed with this driver through a 3rd party router. Settings Tab Label Label is the name of the item as displayed in the Device Tree. All items in the Device Tree are sorted alphabetically by label. Folders can be used to organize items. Description Description is optional text that describes the item. It can be any descriptive text or be left blank.
Calculations A calculation reads points from one or more devices and performs a calculation on them, such as average, minimum or maximum. Custom calculations can also be used. Calculations may be used on graphics, trends, alarms and other calculations just like physical points. Add a calculation in the Device Tree by right-clicking the desired node — it can be a site, driver or device. The Calculation Wizard then appears. After the calculation has been added to the tree, left-click it to edit it.
Calculation Editor A calculation is edited by left-clinking its node. Points must be dragged from the device tree and dropped in the points list. Drop every point that will be part of the calculation. The order of the points is generally not important unless a custom function is used. Function Select the function to perform on the points in the point list. For example, to average three temperatures, drag the three temperature points to the point list and select "Average".
Control Points A Control Point, usually referred to as just a "point", is any input, output, variable or property on a device that a value can be read from, and possibly allows a new value to be written to it. At least one point is required for the unit to do anything useful. Most systems will have dozens or hundreds of points. For point types see the Analog Point Wizard, Digital Point Wizard, Multi-State Point Wizard, Date/Time Point Wizard and String Point Wizard.
Group Settings Tab These determine which user groups can see this item in the tree. Unchecking the default “Allow Everyone” enables selecting individual groups. If a group cannot see an item, items under it are also unseen. There are “Check All” and “Uncheck All” buttons in the upper-right corner to make major changes easier. Advanced Tab Name Name is used for advanced features. If left blank, it will be assigned automatically. It is recommended that the default value not be changed.
Device Tree The device tree appears on the left side of the main window. It displays all interactive items in the system. Each type of item is represented by one of the following icons: Alarms — Monitors specified conditions and generates an alarm message and optional email alerts. Calculations — Reads the value of one or more points and performs a calculation on them — for example, averaging several temperatures. Devices — Any physical device, panel or I/O unit in the system.
Adding Items Right-clicking an existing item in the tree will display a popup menu with options to create new items. The items available will depend on the type of item clicked. Editing Items To edit any item, right-click it and select "Properties". An editor screen specific to that item will appear. Save as Template Right-click any item and select "Save as Template" to save the item — and all sub-items beneath it — as a single template. This template may later be restored to clone the items.
Drivers A driver is a physical network or logical grouping of devices based on the protocol they use. For example, an entire LonWorks network is a single driver. Supported devices include: LonWorks Driver Modbus Serial Driver Modbus/TCP Driver BACnet/IP Driver BACnet MS/TP Device This screen is used to configure access to a single device on a BACnet/MS/TP network. Settings Tab Label Label is the name of the item as displayed in the Device Tree.
With this you can scan the BACnet internetwork to confirm that the new device properties are appropriate.
BACnet MS/TP Driver ESI Point Addressing Addresses for ESI points are actually just the commands used to read and write the desired data — with an optional format specifier. For example, the address for the "Name" of the device is simply: N When the point is read, it will send out the command "N?" and wait for a response. When the user changes the name, it will send out "NTheNewName".
Folders Folders are used to organize tree items. They are typically used to contain a single type of item, such as all points on a device, all schedules, or all devices in a specific area. Any type of item may be placed inside a folder, including other folders. On a system with many items it is important to keep them organized for ease of use. One organizational system might be something like: Figure 15 — Folders in the Device Tree But there are no built-in limitations on how items are organized.
Graphics Wizard Graphics allow for visual representations of areas, floors, buildings or hardware systems. The available components include text labels, checkboxes, LEDs, seven-segment displays, etc. GIF Animations are also supported. You can display a Graphics Wizard by right-clicking on major nodes in the Device Tree. The major modes are Site, Driver and Device. Settings Tab Label Label is the name of the item as displayed in the Device Tree.
Graphic Components The button displays the Component Templates dialog of two sections: a folder / file tree on the left and a label / preview section on the right. The three component categories are: Display Only Display and Control Miscellaneous Components Display Only Components These components display the state or value of points — but do not allow changing the value. LED This round LED (light emitting diode) has the following properties: Colour — This sets the ON colour.
Minimum — The minimum point value used to control animations. See "Animate when…" above. Maximum — The maximum point value used to control animations. See "Animate when…" above. Stretch to Fit — Allows the animation to stretch or shrink, otherwise it displays at default size. Maintain Aspect Ratio — This preserves the width / height ratio as the animation is resized. Smoothing — This softens resized animation edges. (Takes more memory, so use cautiously.
Text Label This can display the value, status or engineering units of a point. It can be used without a point to display titles or information and may also link to other screens or even web sites. Text Tab Text — The displayed text can include codes to embed point information. Examples: The code "Temperature = @V" displays Temperature = 74.3. "The @L is @V (@U)" displays The Outdoor Temperature is 81.4 (Deg.F). Text can include HTML tags. See HTML Help for more information.
Miscellaneous Components These components do not require points. Gradient This can be a background to give the graphic a less "flat" look, or a box to visually distinguish components. (Right-click the gradient and "Send to back" to avoid hiding other components.) Start Colour — This is the starting colour of the gradient. End Colour — This is the ending colour of the gradient. The start and end colour should usually be fairly close, for example, black and grey.
Graphic Screen Editing Left-click a graphic icon in the tree to add, delete or change graphic component properties. Components (visual items on a graphic screen) include text labels, check boxes, animations, etc. Adding Components To add new components to the graphic, drag an item from the device tree and drop it on the graphic. A component selection dialog will be displayed allowing selection of a component to use for the item.
Toolbar Buttons View Mode — Click to change from Edit mode to View mode. Save Graphic — Click to save changes made to this graphic. Edit Properties — Click to edit the Graphic Properties dialog — which includes background options. Align Components — Click to display the Align dialog — or the down arrow for quick options. Size Components — Click to display the Size dialog — or the down arrow for quick options. Cut to Clipboard — Click to remove selected components from this graphic to the clipboard.
Groups Database Access is controlled by a system of Groups and Users. Groups are assigned certain permissions and then users are added to those groups. Users must belong to at least one group. The database screen is divided into two sections: a list of groups on the left, and the settings editor on the right. List of Groups At the top of the list are tabs that may be used to organize groups.
HTML Help Supported HTML tags for Text Label formatting are: TAG EXAMPLES RESULTING EFFECT Bold Text — This is bold text. This is bold text. Italic Text — This is italic text. This is italic text. Underline Text — This is underlined text. This is underlined text. This is bold italic text. This is bold italic text. Font Size This is size 4 text. This is size 4 text.
Custom Help Files To help make custom help files integrate with the built-in help system, use the following tags to ensure that your custom help files will look like the built-in help — even if the help files formatting changes. Major heading: Example:
This is a major heading
Effect: Minor heading: Example:
This is a minor heading
Effect: Useful tip: This is a minor heading Example:
This is a useful tip.Links Links are used to access other units, web pages or other web content. Settings Tab Label Label is the name of the item as displayed in the Device Tree. All items in the Device Tree are sorted alphabetically by label. Folders can be used to organize items. URL The URL of the link. Enter a complete URL including http:// if necessary. For links to other units, use the format http://xxx.xxx.xxx.xxx. Do not include '/index.html' or '/index.pih'.
LonWorks Device This screen is used to configure access to a single device on a LonWorks network. Settings Tab Label Label is the name of the item as displayed in the Device Tree. All items in the Device Tree are sorted alphabetically by label. Folders can be used to organize items. Neuron ID The Neuron ID is the six pairs of hexadecimal numbers displayed on most LonWorks devices. It can usually be found on a sticker somewhere on the device itself.
LonWorks Driver This screen is used to configure a BASV-LON interface to access a LonWorks network. Settings Tab Label Label is the name of the item as displayed in the Device Tree. All items in the Device Tree are sorted alphabetically by label. Folders can be used to organize items. Description Description is optional text that describes the item. It can be any descriptive text or be left blank. Interface Serial # This is the eight digit serial number found on the back of the BASV-LON interface.
LonWorks Point Addressing LonWorks addressing supports three separate modes: Mode 1 Mode 1 is the standard mode and can be used with the majority of LonWorks points. The format is: 1,NVindex,SNVT NVindex = The Network Variable Index of the point. SNVT = The Standard Network Variable Type of the point. Example: 1,15,9 Mode=1, NV index=15, SVNT=9 (count_inc) Mode 2 Mode 2 is the most flexible, but also the most complicated.
Examples: 2,12,9,4,0 Mode=2, NV index=12, SVNT=9 (count_inc), Offset=4, DataType=0 (unsigned short) This example will read the data structure at NV Index 12, take a single byte (DataType 0) starting at byte 4 in the structure, and convert it to a value of type count_inc (SNVT 9).
Supported SNVTs Below is a list of supported Standard Network Variable Types. See documentation from Echelon for more information about these SNVTs.
Mobile Interface When accessing the BASview from an Android, iPhone or similar device, Adobe Flash technology is often not an option. Even if your device uses flash, it could be difficult to properly display the BASview graphics and interact with it. For such cases, the limited functionality Mobile Interface is available using HTML and can be used with a computer browser, if desired. But regardless of how you access this interface, JavaScript and cookies must be enabled in your browser.

Modbus Point Addressing Modbus point addressing is fairly simple for the majority of Modbus points, but can get complicated because of inconsistencies in the way some devices implement the standard. Important notes: The documentation of some Modbus devices will list holding registers as 40,005 rather than just 5. If the address given is greater than 40,000, you will usually need to subtract 40,000 from the number and use HREG5 instead of HREG40005.
Modbus Serial Device This screen is used to configure access to a single device on a Modbus serial network. Settings Tab Label Label is the name of the item as displayed in the Device Tree. All items in the Device Tree are sorted alphabetically by label. Folders can be used to organize items. Description Description is optional text that describes the item. It can be any descriptive text or be left blank. Address The Modbus address of the device (1–254).
Modbus Serial Driver This screen is used to configure a BASV-MOD interface to access a Modbus serial network. Settings Tab Label Label is the name of the item as displayed in the Device Tree.

Multi-State Point Wizard Below are the settings for points with a point type of multi-state. Multi-State Settings Tab Multi-State Text The multi-state text setting allows the point to be displayed as something other than numbers. Several preset pairs of multi-state text labels are available in the drop-down box above the edit area. Any custom labels may also be used by typing directly in the editing area.
Network Settings The network settings must be set to match the network where the unit will reside. A short description of each setting appears below. Please consult a networking book or web site if you need more information. Network Tab For network changes to take effect, select "Reboot" from the Admin menu. A reboot inevitably produces an "HTTP request error" until the reboot is completed. Type Currently, only a static connection is supported. DHCP will be supported in the future.
SMTP Server This is the address of the Simple Mail Transfer Protocol (SMTP) server to use when sending email. SMTP Port This is the port number used by the SMTP server. Authentication Required Select this option if the SMTP server requires user authentication. Username This is the username for the SMTP server authentication. Password This is the password for the SMTP server authentication. Sender This is email address of the sender of all email.
Node Manager This allows viewing the status of all tree nodes of a given type and, in some cases, to enable or disable them. Only users with permission to manually modify points are allowed to enable or disable nodes. Several controls may be used to sort, limit or change what is displayed in the list: Filter — Type a word or phrase here and press Enter to display only nodes that contain that word or phrase in any column. Refresh Button — Refresh the node list from the server.
Point Addressing Each protocol requires a different point addressing system. Select one of the following for more details.
Modbus Point Addressing BACnet Point Addressing ESI Point Addressing Programs Add a program in the Device Tree by right-clicking the desired node — it can be a site, driver or device. The Program Wizard then appears. After the program has been added to the tree, left-click it to edit it. See Program Editor for more information. Program Wizard Settings Tab Label Label is the name of the item as displayed in the Device Tree. All items in the Device Tree are sorted alphabetically by label.
Edit Tab The edit tab is where the program options are set and the actual programming is entered. Enable Execution Every x Seconds Check the box to enable the program for execution. Unchecking the box prevents the program from automatically executing. If the program is enabled, the seconds to wait between executions of the program may be specified. It is recommended that the seconds be set to the highest value possible that will allow for proper operation.
Programming Reference The following is a reference guide on writing Python programs for the BASview. For more on setup and configuration of programming nodes — and an explanation of "reference names" see the Program Editor. Overview Programs for the BASview are written using a modified version of the Python programming language. Python is a very easy to learn language, but can scale up to more complicated tasks when necessary. The BASview itself makes extensive use of Python internally.
Program Execution Before the program is executed for the first time (after it is edited and saved, or after a reboot), all of the points the program requires are read from the network and only then is the program executed. If one or more points could not be read properly, because of an offline device or other reason, the program will not be executed. At each execution, the program is run from the top to the bottom and then ended.
Saved Variables Normal Python variables lose their value every time the program completes a run and are undefined at the beginning of the next run. It is sometimes useful to be able to remember a value so it may be used on the next execution of a program. This is supported by the setVariable and getVariable functions. setVariable("bias", 12.5) myBias=getVariable("bias") #store the value of bias #get the value and store in myBias Note the required quotes around the desired variable name ("bias").
The solution is to use the built in timer. Each program has its own timer that is continuously incremented in the background. It always returns a value equal to the number of seconds the program has run (since it was saved or since reboot) — or since it was last cleared.
Built-in Functions The following is a list of the built-in functions and a short description of each. getValue(@referenceName) Get the value of a point specified by the referenceName. setValue(@referenceName, value, overrideTime=0) Set the value of a point specified by the referenceName, to the value given in the second argument. An optional override time in seconds may be given as a third argument. If the override time is not supplied, or set to 0, the point will retain the value indefinitely.
Read a global variable. See "Global Variables" above for more information. Returns zero if a variable called "name" has not been previously set. setGlobal("name", value) Set a global variable. See "Global Variables" above for more information. removeGlobal("name") Remove a global variable from the list. See "Global Variables" above for more information. disable() Disable this program. It will never execute again until it is manually enabled in the Program Editor.
Revision History Atop each Help page is a link to the page which details the Revision History. Runtime Wizard A Runtime is invoked by right-clicking a device driver in the Device Tree. It monitors a set of user-defined conditions and increments a timer while the conditions are true, and optionally sends email alerts when the accumulated time exceeds a specified limit. Once the runtime is added to the tree, left-click it to edit the conditions. See Runtime Editor for more.
Runtime Editor The runtime editor is displayed by left-clicking the tree icon. It allows editing of the settings of a runtime accumulator. A set of conditions are defined (such as a fan running) and when the conditions are true, the runtime is incremented to keep track of how long a piece of equipment has been used. Runtime can also server other purposes.
Message Tab Message This is the message saved to the database and emailed when the runtime is exceeded, or at specified intervals. The message may contain the following codes to embed information within the text: Example: "@L2 has accumulated @R hours of runtime." is recorded as "Fan2 has accumulated 114.35 hour of runtime.". Notifications Tab Email to Groups Select the list of user groups that should receive runtime messages.
Schedules Schedules allow for control of several points based on the time of day. Schedules are either active or inactive. Active means the current time of day falls within one of the specified time periods. Up to 32 points can be controlled by each schedule. An active and inactive value may be defined for each point. For example, the schedule is active from 8am to 6pm and a setpoint is modified to 72 during active periods and to 78 during inactive periods.
Exceptions Tab An exception is a single date or a range of dates where the desired active periods differ from the normal schedule. Examples of exceptions would be holidays or special events. Up to 32 exceptions may be defined on each schedule. Clicking anywhere on an empty exception entry will create a new exception and allow selecting the date(s) for the exception. Exception time periods are created and edited the same as normal time periods. See above for more.
Schedule Wizard Schedules allow users to set active and inactive periods for each day of the week, and special exception dates, or holiday periods. Schedules allow multiple points to be changed to one set of values when the schedule is active, and another set of values when inactive. Once the schedule is added to the tree, left-click it to edit it. For more, see Editing Time Periods. Settings Tab Label Label is the name of the item as displayed in the Device Tree.
Site Settings The site settings are only used in the Info screen. They are for informational purposes only and do not affect the operation of the system. General Tab Site Description This should be a general description or name of the site (up to 32 characters). Address/Details This should be the address of the site — with any other information desired (up to 512 characters). Contacts Tab Emergency Contacts This is whom to contact in case of an emergency (up to 1024 characters).
System Status This displays information on memory usage, node counts and the status of devices on the network. Unit Serial # This is the Serial Number of the BASview. It is also listed on the Login Screen. MAC Address This is the Ethernet Medium Access Address of the BASView. Scan Time This is the number of seconds it takes the BASview to process all schedules, trends, runtimes, alarms, etc. Memory This displays total and available memory.
Toolbar The toolbar at the top of the screen is used to access several features. The exact buttons displayed will depend on the access permissions of the current users. Home — Display the "home" page of the current user. This will be the screen defined in the group the user belongs to or the screen the user has selected in his personal settings. If neither of those has been defined, it will display the Site Information page.
Trends Trends automatically record point values at specified intervals to allow for later viewing. Both a graphical line chart and a tabular text view are available. Chart Tab Depending on the way it is configured, the chart tab displays either one or two separate charts. The upper chart normally displays analog values such as temperatures. The lower chart displays digital (On/Off) values, and values with low, small ranges such as equipment modes (Off/Heating/Cooling) or status (Off/On/Auto).
Chart Selection Column Points may be forced to appear in either the upper or lower chart. Select "Auto" to have the trend automatically decide which chart it should appear in based on the values of the data. Colour Selection Column Each point can have a specific colour assigned to it. Click a colour box to select a new colour. Recording Interval Selection Click the drop-down list to select a recording interval.
Users Database Access is controlled by a system of Groups and Users. Groups are assigned certain permissions and then users are added to those groups. Users must belong to at least one group. The database screen is divided into two sections: a list of users on the left, and the settings editor on the right. List of Users Atop the list are tabs used to organize users. Right-clicking the tabs will display options to create, delete and rename tabs and to remove users from a tab.
