This screen lets you configure the signals that will generate Control
Changes. When a
primary equipment unit (usually a central unit) makes a request for control changes to the
equipment, the equipment will send it the
ID for any signal labeled as Control Changes
whose status has changed since the last time a request was made.
The fields shown in the
Detail tab are:
- Signal Type: drop-down list containing the groups of signals that collect- the
equipment's digital signals. For more information, see section Signal types. The list of available signals will depend on the selected group.
- Available Signals: list of digital equipment signals belonging to the selected group in
signal type. Signals that can be configured as control changes include all equipment- defined signals and user-defined signals that are included in the configuration. A maximum of 2048 Procome control changes can be labeled.
- Transmission Cause to be Generated: transmission cause generating the signal on
change of status. Indicates the transmission cause that is activated when a change in the digital signal associated with the control change (ISC) occurs. The drop-down list contains a list of the configured Transmission Causes. For further information, see Transmission Causes below. The control change does not necessarily generate a transmission cause (default option). The maximum number of signals that can generate a transmission cause is 256.
- Associated Transmission Causes: causes for the change in a digital signal (ISC or
control change). It is used to determine the reason for the change. One control change can be associated with different transmission causes; as a result, a complete list of transmission causes defined for the configuration is displayed under the Description heading (see Transmission Causes further below). A checkbox is displayed alongside each of the cause descriptions. The checkbox (titled Act) indicates whether the attached transmission cause is associated with the Procome control change (checkbox marked) or not (no marks in checkbox).
- PROCOME Change: this checkbox indicates whether the selected signal is labeled as
a Procome control change (checkbox marked) or not (no marks in checkbox). A maximum of 2048 Procome changes is allowed
- Change Number: Procome label associated with the control change. Each time a new
control change is enabled, this value is established by default at the first free value for control changes. The user can change it in order to give it the desired value. Two digital signals cannot be labeled with the same Procome change number
Valid Range: 0-2047.
Default Value: first free number starting with 0.
Transmission Causes Button: this button accesses the screen for configuring valid
Transmission Causes. See Transmission Causes below.
Pressing the List tab transfers you to the page listing the set of signals labeled as Procome control changes, together with their associated parameters. As indicated earlier, everything that is configured in the Detail tab can be configured in the List tab. To add or delete signals labeled as Control Changes simply right-click on the mouse and select the desired option, as was indicated for general format and handling of screens when discussing the List Page.
The List and Detail field matches are as follows:
Change Available Signals marked as Change
Cause to be Generate Transmission Cause to be Generated
Change Nº Change Number
COTs Mask Associated Transmission Causes
To configure the Cause to be
Generated and the COTs Mask
associated with a control change from this page, double-click on the Cause
to be Generated checkbox or the COTs Mask checkbox for the desired
control change. The screen to the right is displayed when this is done. The data are configured in the same way as described above for the List page.
Transmission Causes Transmission Causes
are defined as a set of identifiers that pinpoint the reason for a change in the control signal. Some signals labeled as control changes are also capable of changing the active cause when their status changes. In this way, changes posted by communications can be sent together with an associated cause indicating the reason for
the change.
The screen shown on the following page is used to configure the Transmission Causes. The description and configurable parameters for a transmission cause are displayed at the top, under the Detail title. The different causes can be accessed in two different ways:
- Using the Navigation Buttons located on the right side of the screen (for more
information about this type of control, see Using Controls).
- Placing the cursor on the desired cause in the list displayed at the lower portion of the screen under the heading Complete List of Transmission Causes. This list shows all the causes enabled up to that moment, in addition to the parameters associated with each cause. The maximum number of Transmission Causes that can be configured for each piece of equipment is 32.
The fields that can be configured on this screen are:
- Identifier: number identifying the transmission cause when sent by communications.
(Procome).
Valid Range: 0-255 Default Value: 100
- Validity (ms): valid time of the cause. This is the time the associated cause is active in
the equipment. This time starts to count the moment the status, or the control change, signal that 'generates the cause' is changed. The time is expressed in milliseconds.
Valid Range: 0 -10000 ms Default Value: 0
- Description: the description given to the cause in order to identify it. This description is
what is displayed in the control changes configuration screen (see Control Changes). - Delete: deletes a transmission cause. When the transmission cause is deleted, the
masks and cause generating signals associated with the control change signals are recalculated.
- New: enables a new control signal with default values: Identifier: 100
Valid Time: 0
The maximum number of valid Transmission Causes per configuration is 32.
3.7.2.c Commands
This screen lets you configure the commands that will be sent via communications to the Procome protocol.
The commands selected here to be used in communications can be referenced from Zivercomplus®, and are displayed under the Actions node. The commands are divided into two groups: commands defined in the configuration as Control Commands and those defined as Protection Commands. Each group is placed under a different node (though both are subnodes of Actions) so that the communication commands defined here can be operated from Zivercomplus®.
The commands that can be operated through communications are those actions that were configured when defining the different command elements. For more information about the command elements or their associated actions, see section Commands.
The fields shown in the Detail screen are: - Command
Element: drop-
down list with the command elements defined in the configuration. The command element is completely user- configurable and can represent any kind of command, e.g. from a signal up to a breaker. For more information about the
- Available Orders: list with the set of available actions for the element selected in the
previous list.
- Procome Command: this checkbox indicates whether the selected order is labeled as
a Procome control change (checkbox marked) or not (no marks in checkbox). A maximum of 1024 Procome commands is allowed.
- Order Type: indicates whether the command is a control command or whether it is
considered a protection command.
- Order Number: Procome command label associated with the order for sending via
communications.
Valid Range: 0-1023
Default Value: First free number (not used, starting with 0).
The order number does not have to be unique. Orders associated with the same Procome label can exist, provided the order type and DCO do not coincide simultaneously. For example, the same order number can be used for two actions, both of them labeled control, as long as one of them has the DCO set to ON and the other has it set to OFF. The configuration module will be capable of making this change when the user decides to use the same Procome order number.
However, it will not allow that both an order's number and parameters match another's. If the user tries to perform this operation, the module will not allow it, displaying a warning reminding the user of the reason for this prohibition.
- DCO: Identification of the order type to allow double commands. Valid values are ON
and OFF. As noted in the previous point, two label orders with the same Procome number, order type and DCO cannot coexist.
Pressing the List tab transfers you to the page listing the set of command actions labeled as Procome orders, together with their associated parameters. As indicated
earlier, everything that is configured in the Detail tab can be configured in the List tab.
The List and Detail field matches are as follows:
Element Command Element
Order Available Orders
Procome Procome Command
Order Type Order Type
Proc Nº Order Number
DCO DCO
New orders cannot be included in this list, since all orders have to be associated with the defined command elements. To enable the order as a Procome Command, activate the checkbox marked Procome, just like in the List area. To make the order a non-Procome command, deactivate the checkbox.
