a General Format and Screen Handling

The different communication screens are organized according to the following format:

The main screen contains a page frame, that is, there are two configuration areas that are selectable by clicking on a tab, so only the information in the active tab is displayed. The two tabs available for these screens are the Detail and List tabs. The protocol option parameters can be configured in either of the two areas. The basic difference between the two is that the

Detail tab only shows information about the selected signal, while the List tab provides a

complete list of the configured signals with their respective parameters.

The Accept and Cancel buttons are used the same way as described in section Using Controls.

 Detail Page

At the top of the Detail page, a drop-down list is displayed with the full list of the signals that can be configured for communications. When a signal is selected, the data representing the communication parameters at the bottom of the screen are updated. For a signal to be included in the communications data, simply activate the checkbox identifying the protocol configuration option. For example, to include a specific signal as DNP3 contact, the desired signal must be selected from the list of Available Signals.

Once the signal is displayed as active in the list, the labeled checkbox is enabled (for this example, as DNP3

Contact). In doing this,

the ZIverlog® configuration module enables the rest of the controls in order to

configure the communication signal

parameters, and it calculates the DNP3 contact number while giving the signal. This will be the first free communication number

at that time. The number can be edited by the user by means of the relevant numeric control. The rest of the parameters are also initialized with their default values.

 List Page

The List area includes all the signals that have been enabled for communication in the left-hand column. The different parameters applied to each of the signals are displayed in the two columns at the right. New signals are enabled on this screen by right-clicking the mouse and selecting the

New option (see section

Using controls). Similarly, to delete configuration signals, select the signal you wish to delete and then right-click the

3.7.2 Procome

This option of the Communications menu opens a new submenu with the options the equipment allows to be configured for this protocol. By selecting the desired submenu option, you can access the screens for configuring the Events, Control Changes, Commands, Metering

Values, Meters and Digital and Analog Outputs for communication using the Procome

Protocol.

3.7.2.a Events

This screen lets you configure the user-defined signals that will generate an event. Here is where the control events, that will complement the equipment-defined protection events in the log file, are configured. These events will be stored in the log file with the same format as the protection events, except that the valid range of the records will be from 40000 to 40023. For each of the records, the first 32 bits are assigned as activation bits and the remaining 32 bits are deactivation bits. The activation and deactivation bits will be paired, although both status conditions are not required to generate an event. The fields shown in the Detail tab are:

- Available Signals: drop- down list containing all user-defined signals during configuration (see Digital Signals). - Event Description:

The user can edit

the text representing the

event in this text box. By default, the description will match the

description of the signal whose change will generate the event. When the event log is ®

- Activation Generates an Event: if this checkbox is marked, an event is generated

when the selected signal (in the list of available signals) is activated. If it is not marked, an event is not generated.

- Deactivation Generates an Event: if this checkbox is marked, an event is generated

when the selected signal (in the list of available signals) is deactivated. If it is not marked, an event is not generated.

- Record Number: the number of the record where the event information is stored. The

event information is stored at a specific position in the record. This position is a record bit. Each record can store up to 64 positions or bits. The first 32 are assigned as activation events, and the last 32 are for deactivation events.

Valid range for control events: 40000- 40023

- Activation Bit: position (bit) in the record where the activation event is stored. As

indicated earlier, the activation and deactivation events are paired, although the two are not required to be activated simultaneously. However, their position is always separated 32 bits. The configurations module makes this change automatically. When an event is enabled, the first free position (by pairs) existing in the first record with free positions is calculated.

Valid range for control events: 0-31

- Deactivation Bit: position (bit) in the record where the deactivation event is stored. Valid range for control events: 32-63

The List tab lets the user configure the same fields as in the Detail section.

The List and Detail field matches are as follows:
