KITZ 10x Courier Interface Units

PROTECTION

The KITZ interface units provide conversion between K-BUS ports and IEC60870 format data. They providethe user with an EIA232 (RS232) serial connection forinterfacing to master stations or computers using aCourier software package.

Different types of Courier software are available for usewith the KITZ, however it can be used to directlyinterface to integrated SCADA (Supervisory Control andData Acquisition) systems written around the Courierprotocol.

The Courier language was developed specifically forcommunication with substation devices such as relaysand measurement devices. Therefore through the useof KITZ and the Courier Protocol, the user has access tothe device menu structure called the Courier Database.This enables reading and changing of device functions,settings, measurements or statistics.Courier protocol is most commonly used as a K-BUSsystem, consisting of a screened twisted pair of wires.This arrangement is suitable for communicating withupto 32 devices at a maximum distance of 1km inelectrically hostile environments.

3 KITZ Models are available in the KITZ10x range

> KITZ101 - Interface suitable for desk-top use

> KITZ102 - Interface suitable for use at rear of panel

> KITZ103 - Interface for Optimho relay, OPTICOM to K-BUS, for use at rear of panel

APPLICATION

> KITZ101/102

The KITZ101/102 interface may be used to interfacebetween 1 and 32 Courier devices to:

• PC Serial Port for local substation use

• Via compatible modems and telephone network forremote access

• An RTU (Remote Terminal Unit) for integration inSCADA systems with Courier protocol capability

The KITZ101/102 converts K-BUS to IEC60870 frameformat for use in computer based systems. It istypically applied in substations where a number ofcompatible devices could be located, along withconnection equipment such as modems, RTU's or otherSCADA equipment.

KITZ can provide local and remote access via K-BUSfor setting changes, disturbance and event recordextraction and also for Circuit Breaker operations.

It should be noted that Protection tripping or blockingsignals are not routed on the K-BUS/KITZ system andspecial provision must be made using dedicatedequipment or connections for such signals. Howeverremote tripping and closing commands can betransmitted via K-BUS and KITZ where available aspart of integrated control systems.

KITZ101/102 may be integrated into intelligent SCADAsystems where all or part of the system is available onthe Courier protocol. Such systems simply require anEIA232 or Fibre Optic (via converters) port on theSCADA or RTU for connection to the KITZ101/102.SCADA systems without the use of the Courierprotocol may also utilise KITZ by use of other Protocolconverters, for example KITZ202 for Modbus orKITZ204 for IEC60870-5-103 based systems.

Typical application of the KITZ101/102 is shown infigures 1 to 2.

> KITZ103

The KITZ103 allows the user to interface the Optimho(LFZP) range of distance protection relays to the K-BUS network. Housed in the same case formounting identical to KITZ102, the KITZ103 providesprotocol conversion between Opticom (the protocolused by Optimho relays) and Courier Protocol. OneKITZ103 is require for each Optimho relay which isthen connected to the K-BUS in the same way as anyother K-BUS device. It then allows the most commonlyneeded information exchanges with the Optimho relayas if it were any other K-BUS Device. Additionally, theKITZ103 allows use of OPTICOM software (dependanton version) to access the Optimho relay over the K-BUS connection.A typical application of KITZ103 is shown in figure 3.

FUNCTIONS

> Functions of KITZ101/102

• Interface between K-Bus and IEC60870 data formats

• Modem Interface.

• Time-tagging of K-BUS messages

The main function of the KITZ101/102 is to interfacethe K-BUS communication link to a PC based system(IEC870 data format).It can also be configured to interface with a remotemaster station. Communication may be establishedvia telephone networks and modems to access thedevices in much the same way as a local connection.In addition, the KITZ101/102 can also be configured toadd an IEC870 format date and time tag to anyreceived K-BUS messages that contain anunsynchronized millisecond counter. This allowsaccurate sequence of events (SOE) despite modemsor transmission delays on the IEC870 network. Theinternal Real Time Clock is backed in case of loss ofpower, by an internal battery.

> Functions of KITZ103

The function of the KITZ103 is different to that of theKITZ101/102. The KITZ103 is a protocol converter foruse with the Optimho (LFZP) range of relays. Itprovides conversion between the Opticom protocol(RS232) and Courier (K-BUS). It provides this partialinterface by conversion of certain information into asimilar format as used by K-Series relays. Thisinformation includes fault records, measurementvalues and allows active setting group changes. TheKITZ103 automatically 'logs on' to the Optimho withwhich it starts up. Once this connection is made, it willstay active to detect and extract new fault records andmeasurement values. The KITZ103 can be 'logged off'by the user via the Courier interface or by pressing theRESET key on the relay user interface. The unitautomatically extracts any fault record generated bythe Optimho, and also generates a Courier event andpasses this on K-BUS. This event is created from thetime, date and description of the extracted fault. Asthe KITZ103 acts as a protocol converter for Opticomto Courier, the KITZ103 also inserts an Opticomidentifier, meaning that later versions of the Opticomsoftware (V5.00 or above for Opticom100 and V3.00 orabove for Opticom 140) can be used over the K-BUSinterface to access the relay. This includes the abilityto change relay settings.

HARDWARE DESCRIPTION

The KITZ10x interfaces are housed in a case 57.5mmx 163mm x 216mm Deep. This is available for Desktop(KITZ101) or Rear of panel mounting (KITZ102 orKITZ103).

The functions of the KITZ10x are controlled bysoftware, run by a 16bit microprocessor. A SerialCommunications Controller controls all communicationfunctions. The KITZ10x has two communicationchannels, one K-Bus and one RS232/IEC870, eachable to receive and transmit via independentcommunication ports. Both RS232 and K-BUS portsare located at the rear of the KITZ10x. The K-BUSport is a 3 terminal connection (2 signal plus screen)and is not polarity sensitive. The RS232 port is a male25 way D-Type connection, which normally requires aswitched or 'null-modem' connection.

USER INTERFACES

> Front Panel

The front of the KITZ10x interfaces contain 5 LED's to indicate:

• Power On

• Transmit K-Bus

• Receive K-Bus

• Transmit IEC870

• Receive IEC870

8 switches are also located alongside the LED's forconfiguration of the interface.

> Communications Interface

KITZ10x support a variety of Courier basedcommunication packages. The latest MiCOM S1enables communication with the rear ports of anyconnected courier devices, allowing full configurationas if it were the front port. This allows configuration ofthe full K-BUS spur of devices without the need forseparately connecting cables to each device's frontport, the process can even be carried out remotely byuse of a suitable modem. Previous versions ofsoftware such as Courier Access (CAS), ProtectionAccess Software & Toolkit (PAS&T), COURIER-COMM, LFZRCOM or OPTICOM (KITZ103 - subject toversion) also function well with KITZ10x maintainingimportant backward compatibility.
