The Begin date (or Start or Start date) property specifies the start date and time for a control (or screen or chart or column) for an absolute date and time view window. The format is MM/DD/YYYY hh:mm:ss AM/PM. The default value is the system date and time at which the control was first added to the screen. Click to change the date using the date picker.

The Begin relative date (or Relative start date or Start) property specifies a wildcard string defining the amount of time by which to adjust the start date and time. The space-separated elements in this string must be of the form: "x-#", "x+#", or "x=#" where # is an integer and x is one of the following unit specifiers: y — Year, m — Month, d — Day, H — Hour, M — Minute, S — Second, and # is an integer. T wildcard is also supported and must be in the form: T, T+#, T-#, where T represent today at midnight, T-1 is yesterday at midnight, and T+1 is tomorrow at midnight, etc. Any integer can be used. For example, H-8 represents data from the 8 hours before the current hour, d+3 represents data 3 days after the current day, and d+2 H+1 M+30 represents data 2 days, 1 hour and 30 minutes after the current date and time. d-4 H=6 sets the relative start date and time to four days ago (d-4) at 6:00 a.m. (H=6). See Date and Time Wildcards for more information about adjusting relative time.

The End date (or End) property specifies the end date and time for a control (or screen or chart or column) for an absolute date and time view window. The format is MM/DD/YYYY hh:mm:ss AM/PM. The default value is the system date and time at which the control was first added to the screen. Click to change the date using the date picker.

The End relative date (or Relative end date or End) property specifies a wildcard string defining the amount of time by which to adjust end date and time. The space-separated elements in this string must be of the form: "x-#", "x+#", or "x=#" where # is an integer and x is one of the following unit specifiers: y — Year, m — Month, d — Day, H — Hour, M — Minute, S — Second, and # is an integer. T wildcard is also supported and must be in the form: T, T+#, T-#, where T represent today at midnight, T-1 is yesterday at midnight, and T+1 is tomorrow at midnight, etc. Any integer can be used. For example, H-8 represents data from the 8 hours before the current hour, d+3 represents data 3 days after the current day, and d+2 H+1 M+30 represents data 2 days, 1 hour and 30 minutes after the current date and time. d-4 H=6 sets the relative end date and time to four days ago (d-4) at 6:00 a.m. (H=6). See Date and Time Wildcards for more information about adjusting relative time.

The Override chart dates check box indicates whether to use the screen's dates, when displaying charts for this screen.

The Broadcast facilities check box indicates whether to notify other screens when this screen's facility selection changes. When enabled, and when a screen's facility selection changes, Canvas will broadcast the list of facilities out to all other screens open in the application that are configured to source their facility from <Broadcast>.

See Interscreen Communication for more information about using this property.

The Broadcast SiteService check box indicates whether to notify other screens when this screen's SiteService selection changes. When enabled, and when a screen's SiteService selection changes, Canvas will broadcast the SiteService out to all other screens open in the application that are configured to source their SiteService from <Broadcast>.

See Interscreen Communication for more information about using this property.

The CygNet connection property is used to configure the facility and SiteService associated with this control or screen. Two selection modes are available: a) by Facility tag or b) by SiteService / Facility. This split configuration allows for the inheritance of these properties from other controls, or the specific configuration of the SiteService or the facility, while dynamically changing the other. This use case may be rare; therefore, the Facility tag option is the default.

Click to reveal a drop-down area where you can configure the Selection mode, source SiteService, and source Facility. Each option is described below.

The Selection mode property is used to determine how the control will receive CygNet information from other controls. Two options are available; click the desired radio button:

• Facility tag — The Facility tag selector consists of a Source chooser and Resolve to a relative facility check box. If the Source is <Self> a Facility tag selector and relative facility options are also displayed. Facility tag is the default option.
• SiteService / Facility — The SiteService / Facility selector consists of Source and SiteService and facility choosers.

Sending and receiving facility tags

Some controls on the same screen allow for the sending of facility tag information from one control to another.

1. On the sending control configure the Facility sender mode property to send facility tag information to another control on the same screen.
2. On the receiving control configure the Selection mode property (in either CygNet connection or Point configuration section) to Facility tag and select the Facility Source to the sending control.
3. On the receiving control configure a display tag that associates to a facility property, e.g. %FacilityTag%.

The Facility tag or Facility property is where you specify the source of the facility for the control (or screen) to use. The source for the facility can be explicitly configured for this control or it can be inherited from another control on the same screen, or from the screen, or from another screen. Click to reveal the Facility tag or Facility selector. Options include:

• Source — Options include <Broadcast>, <Self>, or a list of Sender controls.
  • <Broadcast> — Select <Broadcast> to indicate that the facility is sourced from another broadcasting screen.
  • <Self> — Select <Self> to explicitly configure the facility for this control. A Facility tag or Facility selector is displayed, depending on the Selection mode:
    • Facility tag — The Facility tag property specifies the full facility tag identifier for which the control (or screen) is to display data. Click to select a facility using the Select Facility Tag dialog box.
    • Facility — The Facility property specifies the facility for which the control (or screen) is to display data. Click to select a facility using the Select Facility dialog box.
  • Screen — Select Screen to inherit the facility from the screen for this control. By default, the sender is the Screen control if no other senders have been configured. Once Screen is selected Inherited from Screen will display for the Facility property.
  • Sender — A list of sender controls that have been configured with a facility will be displayed. Select the name of the control that will send its facility to this control. By default, the sender is the Screen control if no other senders have been configured. Once a sender control has been specified its name will display in the Source field.

• Resolve to a relative facility — The Resolve to a relative facility check box redirects the source of the facility to a relative facility, overriding the configured source facility. Once selected a list of configured Relative links is displayed. See Using Relative Facilities in Canvas for more information about configuring and scripting relative facility links.
  • Relative link — The Relative link property specifies a list of all available relative facility paths. Click to reveal a drop-down menu of all available relative facility definitions (relative links). Select a link from the list. If an order-in-type attribute is specified for the selected link, the Order in type field will display.
  • Order in type — The Order in type property specifies the attribute value used to represent the order in type (facility ordinal) if the relative facility definition is configured for one. It is possible to have multiple relative facility definition sets with the same definition name. In this case, if the specified Relative link is configured for ordinalization, then you need to configure the attribute value in the box.

The Default chart file property specifies the path to the chart file associated with this screen.
