Actual configuration is based on the entries made in the individual cells. While an try can always be made by clicking on the cell with the left mouse button and then en-tering the appropriate information, the preferred method is to select a cell, press the right mouse button, and use the displayed pull down menu to make the entry.
In certain cases, the pull down menu will offer ; (configured) or B (not configured) as the configuration choices. In other cases, more alternatives will be offered (e.g. / = latched, 8 = unlatched, and B = not configured). Entries resulting in an implausible configuration are blocked and inaccessible to the user.
Configuring Binary Inputs as Sources
Single point indications, double point indications, transformer tap changer indications, and pulse metered values can all be configured as binary inputs. In addition, whether or not binary inputs are activated by the presence of control voltage can be estab-lished. That is,
• “H” (High with voltage active): Control voltage at the binary input terminals activates the indication
• “/” (Low with voltage active): Control voltage at the binary input terminals deacti-vates the indication
Note:
When deleting a group, all information definitions within this group will be deleted.
In addition, a single point indication cannot be configured to a binary input and to CFC as a source at the same time. In this case, an error message would be displayed. Click on 2., and select another configuration.
Figure 5-23 Error Message Resulting from Double Configuration
If a double point indication (DP) is configured to one binary input (e.g., feedback indi-cations from switching devices), the next binary input is also set. If this configuration is undone, the second binary input is automatically deconfigured.
If a transformer tap changer indication is configured to a binary input, the next binary inputs in order are also configured. Their total number is the same as the number of bits configured for the transformer tap changer. If one of these inputs is deconfigured, all related binary inputs are automatically deconfigured.
Configuring a Function Key as a Source
The four function keys on the front of the relay may also be configured as sources in order to establish a link using CFC. In this situation, each function key may be linked with only one internal indication. A function key may be occupied because it has al-ready been set as an operating function for the relay. As delivered from the factory , the device’s function keys F1, F2, and F3 are preconfigured:
In order to configure a new indication, select one of the options (OPEN/CLOSE, ON/
OFF, etc.) from the indication group in the information catalog and drag it to the left Note:
A single logical indication should not be configured to two binary inputs, since an OR-link of both signals is not ensured. The operating program allows only one link, and deletes the first link when a second is established. Use CFC to perform an “25” in-stead.(
F1 operating messages F2 primary measured values
F3 overview of the last eight fault messages
Note:
When an indication is configured to a function key, its factory-assigned function is de-leted. Reestablishment of the factory default function of the F-keys is only possible by initializing the relay with a new factory parameter set created within DIGSI®4. All de-vice settings have to be reentered.
side of the matrix. Upon release, a new row appears in the matrix. If the mouse is po-sitioned at the intersection of this row with column F, and the right mouse button is pressed, a context menu opens (Figure 5-24) in which the function key may be set as a source by clicking the proper choice.
Figure 5-24 Selecting a Function Key
Configuring CFC as a Source
If certain information is created as a result of the implementation of a user defined logic function, this information must appear in the matrix as a source of CFC. Otherwise, this information will not be available to the user for processing by the CFC program.
The user may not configure information to CFC as a source if it is already configured to a binary input.
Configuring Binary Outputs as a Desti-nation
Up to ten (10) information units (commands and indications) may be configured to one binary output (output relay). One indication may be configured to up to ten (10) binary outputs (LEDs and output relays).
During configuration of binary outputs, the user may select, for each output relay (be-sides of the logic function itself), whether it should be latched (/) or unlatched (8). If latched is selected, the output relay remains engaged, even after the indication is no longer present. It must be manually reset by pressing the LED Reset button on the front panel of the relay, or via a binary input with the indication function “!5HVHW/('”, or via the serial SCADA interface. If unlatched is selected, the relay disengages as soon as the indication disappears.
Binary Outputs for Switching Devices
The user must be cautious when configuring binary outputs for switching devices. For switching devices, the type of command (e.g., single or double commands, with or without feedback) is defined and configured to the output relay. If the preset command types are not correct, then appropriate command types can be selected from the In-formation catalog (see also “Entering Your Own InIn-formation” in the previous sub-sec-tion) and inserted into the Configuration Matrix.
Warning!
CFC connection have to be reestablished after renaming of a display text of an user defined information. Within the CFC the old name is shown at the right column. De-lete this connection. Make connection to the desired blocks using the renamed infor-mation.
Figure 5-25 Window Information Catalog (Example: Different Command Types)
If a command with multiple outputs is configured, all binary outputs required in the ma-trix for the configuration are automatically defined. If one of these outputs is deconfig-ured, all other binary outputs associated with the command will be automatically de-configured.
Please pay attention to the comments and switching examples in Section 5.2.1, par-ticularly the fixed defined sequence of relay assignments (TRIP before CLOSE).
When configuring commands, the context menu is dependent on the type of com-mand. In some cases, the selection latched/unlatched is not available. Instead, the al-ternatives are ; (configured), B (not configured), and ) (busy flag). The latter means, independent of the switching direction, an indication is always issued during activation of the switching device.
For double commands with a common output, a fourth alternative & (Common contact) appears. Using this, the binary output may be defined as the common relay (common contact). When this is the case, several double commands with common contacts may be assigned to the same common relay (common contact), thus saving binary outputs.
This assumes the signals at the common outputs have the same potential.
Using the 2EMHFW3URSHUWLHV dialog window, additional properties for commands issued to the switching device may be defined. Thus, the operating mode (pulse or latched) output of a switching command, the seal-in time for pulse commands, the out-put delay of the command, and feedback monitoring may be set (see Figure 5-26). The output delay is only relevant for equipment which removes an indication before the switching is completed.
Example:
Double Command with 2 Contacts (acc. Table 5-1)
Figure 5-26 Dialog Box - Object Properties for a Command with Feedback (Example: Double Command with Single Trip Outputs and Double Close Outputs, CF_D12)
The conditional checks that should be conducted before execution of a switching com-mand can also be defined:
• System Interlocking (Substation controller): in preparation, implemented as of Ver-sion 4.2.
• Zone controlled (Bay Specific Interlocking): Logic functions created with CFC in the relay are processed for interlocked switching.
• Device status (Open/Closed; scheduled/actual): The switching command is ignored and a corresponding indication is issued if the switching device is already in the de-sired position. If this check is activated, switching direction control occurs not only for interlocked, but also for non interlocked switching.
• Blocked by protection: CLOSE–switching command for switchgear is blocked as soon as one of the protective functions or elements in the relay has picked up.
OPEN commands, in contrast, can always be executed. Please be aware, activa-tion of thermal overload protecactiva-tion or sensitive ground fault detecactiva-tion can create and maintain a fault condition indication, and can therefore lead to the blocking of CLOSE commands. If the blocking by protection facility is disabled consider that a blocked restart of a tripped motor feeder is overridden. In this case the manual re-close of the motor feeder has to be interlocked by different means, i.e. CFC. One method would be to use the bay specific interlocking in CFC.
• Double operation: Parallel switching operations are blocked with respect to each other; while one switching operation is being conducted, a second one may not be performed.
• Switching Authority – Local commands: A local control switching command is only allowed if local control is enabled on the relay (via a setting).
• Switching Authority - Remote commands: A remote control switching command is
Configuring a LED Display as a Desti-nation
Single point indications (SP), output indications (OUT), and internal single point indi-cations (IntSP) may be configured to LEDs. When this is done, the user may select whether the indications are to be latched (/) or unlatched (8).
Up to ten (10) indications may be configured to a LED display. One indication may be configured to a maximum of ten (10) outputs (LEDs and output relays).
Configuring an Indication Buffer as a Destination
A maximum of three indication buffers are available for selection: Operation (Event Log) Buffer ((), Sensitive Ground Fault Buffer (6), and Trip Log (7). The indications from protective functions are firmly assigned to these indication buffers. For the oth-ers, Table 5-2 provides an overview of which indication type may be configured to which buffer.
One of the following options should be selected for all configured indication types:
• 2 (on) – the indication is stored in the buffer with the time of its arrival
• RR (on/off) – the indication is stored in the buffer with the time of its arrival and de-parture
• B (not configured) – the indication is not stored in a buffer.
Configuring the SCADA Interface as a Destination
Depending on the SCADA interfaces connected to the relay, the types of information displayed in Table 5-3 may be configured. By placing an ; in the matrix cell, the infor-mation is transferred to connected systems via the SCADA interface.

Configuring CFC as a Destination
Single point, double point, and output indications, as well as limit and measured val-ues, may be configured to CFC as the destination.
Configuring the Default Display and Control Diagram as a Destination
All information, including limit values, may be configured, both in the default and con-trol display. By placing an ; in the matrix cell, the information may be used within the default and control control display. This feature is not available on the 7SJ61_62 se-ries of relays.
Configuring Con-trol Display as a Destination for Command Initiation
Single point and double point indications, transformer tap change indications, and all types of commands may be configured to the control display as the destination. These indications and commands then become available in the relay’s control display for op-erational control.
Configuring the Measured Value Window as a Destination
In addition to the measured values available in the relay, user defined measured and limit values may be configured into the measured value window. These values then become available in the device display in the assigned measurement window.
Configuring the Metered Value Window as a Destination
In addition to the metered values available in the device, user defined pulse and me-tered values derived from the measured values may be configured into the meme-tered value window so that they may be shown at the front display.
Retrieving Device Retrieving the configurations is also possible from the device front. The user may

Any new user defined information is also shown in the display once loaded into the relay from DIGSI®4.
When selecting the 0$6.,1* ,2 menu, either binary inputs, LEDs, or binary out-puts may be selected. Selection of binary inout-puts is illustrated in Figure 5-27.
Figure 5-27 Reading the Configuration in the Display
Information regarding a binary input may be displayed by using the navigation keys to select the binary input. See Figure 5-28.
Figure 5-28 Selection of Binary Input 2
In Figure 5-28, information is displayed regarding binary input 2. The display for binary input 2 indicates that it is configured as the acknowledgment of LEDs using a single point indication with voltage active (High). The present conditions of binary input 2 is also given as 0 (not active). If binary input is active, a 1 is displayed.
Assignment of LEDs may be indicated at the relay, itself, using a replaceable labeling strip with plain text on the front panel located, directly next to the LEDs.
