    Introduction The device family SIPROTEC 7SJ80 devices is introduced in this section. An overview of the devices is presented in their application, characteristics, and scope of functions. Overall Operation Application Scope Characteristics SIPROTEC 4, 7SJ80, Manual E50417-G1140-C343-A8, Edition 12.2017...

  • Page 20: Overall Operation

    It consists of filters that are optimized for measured- value processing with regard to bandwidth and processing speed. The analog-to-digital (AD) transformer group consists of an analog-to-digital converter and memory compo- nents for the transmission of data to the microcomputer. SIPROTEC 4, 7SJ80, Manual E50417-G1140-C343-A8, Edition 12.2017...
  • Page 21 Voltage dips may occur if the voltage supply system (substation battery) becomes short-circuited. Usually, they are bridged by a capacitor (see also Technical Data). A buffer battery is located under the flap at the lower end of the front cover. SIPROTEC 4, 7SJ80, Manual E50417-G1140-C343-A8, Edition 12.2017...

  • Page 22: Application Scope

    1.2 Application Scope Application Scope The multi-function numerical overcurrent protection SIPROTEC 4 7SJ80 is used as protection, control and monitoring unit for busbar feeders. For line protection, the device can be used in networks with grounded, lowresistance grounded, isolated or a compensated neutral point structure. It is suited for networks that are radial and supplied from a single source, open or closed looped networks and for lines with sources at both ends.
  • Page 23 The USB DIGSI interface on the front cover serves for local communication with a PC. By means of the SIPROTEC 4 operating software DIGSI, all operational and evaluation tasks can be executed via this operator interface, such as specifying and modifying configuration parameters and settings, configuring user-specific logic functions, retrieving operational messages and measured values, inquiring device conditions and meas- ured values, issuing control commands.

    Combination devices are bay devices with protection functions and a control display. Combination matrix From DIGSI V4.6 onward, up to 32 compatible SIPROTEC 4 devices can communicate with one another in an Inter Relay Communication combination (IRC combination). Which device exchanges which information is defined with the help of the combination matrix.
  • Page 550 Device container In the Component View, all SIPROTEC 4 devices are assigned to an object of type Device container. This object is a special object of DIGSI Manager. However, since there is no component view in DIGSI Manager, this object only becomes visible in conjunction with STEP 7.

  • Page 553 An Ethernet network is used for data transfer. IEC address Within an IEC bus a unique IEC address has to be assigned to each SIPROTEC 4 device. A total of 254 IEC addresses are available for each IEC bus. IEC communication branch Within an IEC communication branch the users communicate on the basis of the IEC60-870-5-103 protocol via an IEC bus.
  • Page 554 (energy purchase/supply, energy transportation). MLFB MLFB is the abbreviation for "MaschinenLesbare FabrikateBezeichnung" (machine-readable product designa- tion). This is the equivalent of an order number. The type and version of a SIPROTEC 4 device is coded in the order number. Modem connection This object type contains information on both partners of a modem connection, the local modem and the remote modem.
  • Page 555 Each object has properties. These might be general properties that are common to several objects. An object can also have specific properties. Off-line In offline mode a connection to a SIPROTEC 4 device is not required. You work with data which are stored in files. On-line When working in online mode, there is a physical connection to a SIPROTEC 4 device.
  • Page 556 2, PROFIBUS. It defines the functional, electrical, and mechanical properties for a bit-serial field bus. PROFIBUS address Within a PROFIBUS network a unique PROFIBUS address has to be assigned to each SIPROTEC 4 device. A total of 254 PROFIBUS addresses are available for each PROFIBUS network.
  • Page 557 SIPROTEC 4 Variant This object type represents a variant of an object of type SIPROTEC 4 device. The device data of this variant may well differ from the device data of the original object. However, all variants derived from the original object have the same VD address as the original object.
  • Page 558 Users From DIGSI V4.6 onward , up to 32 compatible SIPROTEC 4 devices can communicate with one another in an Inter Relay Communication combination. The individual participating devices are called users. A VD (Virtual Device) includes all communication objects and their properties and states that are used by a communication user through services.
