Example: K2001 replaces K201 (= first relay in slot 20). Software IEC Initial implementation of the IEC 61850 communication protocol. GSSE In conjunction with the IEC 61850 communication protocol a communication procedure has been implemented that is compatible with previous UCA2 GOOSE for the exchange of binary information within an Ethernet network section. GOOSE For the exchange of binary information in an Ethernet network section the IEC 61850 communication procedure (IEC-GOOSE) has been implemented. ASC Bug fixing: In version –608 the internal timer clock was corrupted during the ASC operative time. This led to implausible time tags added to binary signals, which in turn made fault records difficult to interpret. Protection functions were in no way affected. Bug fixing: In version -605 the offset angle (ASC: Phi offset PSx) was taken into account but by a factor of 10 less than required (for instance when set to 90° an internal value of only 9° was taken into account).

IEC 61850 IEC 61850 was created jointly by users and manufacturers as an international standard. The main target of IEC 61850 is interoperability of devices. This includes the capability of two or more intelligent electronic devices (IED), manufactured by the same company or different companies, to exchange data for combined operation. Now this new communication standard IEC 61850 has created an open and common basis for communication from the process control level down to the network control level, for the exchange of signals, data, measured values and commands. For a standardized description of all information and services available in a field device a data model, which lists all visible functions, is created. Such a data model, specifically created for each device, is used as a basis for an exchange of data between the devices and all process control installations interested in such information. In order to facilitate engineering at the process control level a standardized description file of the device, based on XML, is created with the help of the data model. This file can be imported and processed further by the relevant configuration program used by the process control device. This makes possible an automated creation of process variables, substations and signal images. The following documentation with the description of the IEC 61850 data model, used with the P433/P435, is available: (cid:133) IDC file based on XML in the SCL (Substation Configuration Description Language) with a description of data, properties and services, available from the device, that are to be imported into the system configurator. (cid:133) PICS_MICS_ADL file with the following contents: (cid:133) PICS (Protocol Implementation Conformance Statement) with an overview of available services. (cid:133) MICS (Model Implementation Conformance Statement) with an overview of available object types. (cid:133) ADL (Address Assignment List) with an overview of the assignment of parameter addresses (signals, measuring values, commands, etc.) used by the device with the device data model as per IEC 61850.

The selection which of the two interfaces is to be used to connect to the Ethernet network is made by setting the parameter IEC: Ethernet media. For the optical interface on the Ethernet communications module the user may either select the ordering option ST connector or SC connector with 100 Mbit/s and 1300 nm. The RJ45 connector supports 10 Mbit/s and 100 Mbit/s. The optional Ethernet module additionally provides an RS485 interface for remote access with the operating program MiCOM S1 (function group COMM2). Note: The P433/P435 may only be equipped with the optional Ethernet module as an alternative to the standard optional communication module. Therefore the Ethernet based communication protocol IEC 61850 is only available as an alternative to function group COMM1. Activating and Enabling The IEC function group can be activated by setting the parameter IEC: Function group IEC. This parameter is only visible if the optional Ethernet communication module is fitted to the device. After activation of IEC, all data points associated with this function group (setting parameters, binary state signals etc.) become visible. The function can then be enabled or disabled by setting IEC: General enable USER. The parameter settings for function groups IEC, GOOSE and GSSE in the device are not automatically activated. An activation occurs either when the command IEC: Enable configuration is executed or automatically when the device is switched online with MAIN: Device on-line. Client Log-on Communication in Ethernet no longer occurs in a restrictive master slave system, as is common with other protocols. Instead server or client functionalities, as defined in the 'Abstract Communication Service Interface' (ACSI, IEC 61870-7-2), are assigned to the devices. A 'server' is always that device which provides information to other devices. A client may log-on to this server so as to receive information, for instance 'reports'. In a network a server can supply any number of clients with spontaneous or cyclic information. In its function as server the P433/P435 can supply up to 16 clients with information. U-6 P43X/EN AD/Aa5 // AFSV.12.09770 D /// P433-305-406/407-610 // P435-305-407/408/409-610 P433/P435 -610 Upgrade Documentation (continued) Clock Synchronization With IEC 61850 clock synchronization occurs via the SNTP protocol, defined as standard for Ethernet. Here the P433/P435 functions as a SNTP client. For clock synchronization one can select between the operating modes Broadcast from SNTP Server or Request from Server. With the first operating mode synchronization occurs by a broadcast message sent from the SNTP server to all devices in the network, and in the second operating mode the P433/P435 requests the device specific time signal during a settable cycle. Two SNTP servers may be set. In this case, clock synchronization is preferably performed by the first server. The second server is used only when messages are no longer received from the first server. When looking at the source priority for clock synchronization, which is set at the MAIN function then, by selecting "COMM1", synchronization per IEC 61850 is automatically active but only if this communication protocol is applied. Fault Transmission Transmission of fault files is supported per "File Transfer". Transmission of "Goose Messages" The so-called "Goose Message" is a particular form of data transmission. Whereas normal server-client-services are transmitted at the MMS and TCP/IP level, the "Goose Message" is transmitted directly at the Ethernet level with a high transmission priority. Furthermore these "Goose Messages" can be received by all participants in the respective sub-network, independent of their server or client function. In IEC 61850 "Goose Messages" are applied for the accelerated transmission of information between two or more devices. Application fields are, for example, a reverse interlocking or a transfer trip. In future the "Goose Message" will therefore replace a wired or serial protective interface. According to IEC 61850 there are two types of "Goose Messages", GSSE and IEC-GOOSE. The GSSE is used to transmit binary information with a simple configuration by 'bit pairs', and it is compatible with UCA2. However IEC-GOOSE enables transmission of all data formats available in the data model, such as binary information, integer values or even analog measured values. But this will require more extensive configuration with the help of the data model from the field unit situated on the opposite side. With IEC-GOOSE the P433/P435 at this time supports sending and receiving of binary information.

Transmission is carried out by an Ethernet Standard Protocol, but this is only supported by the associated operating program MiCOM S1 (specific manufacturer solution). Such transmission is accomplished over the same hardware for the network, which is used for server-client communication and "Goose Messages". Available are all the familiar functions offered by the operating program MiCOM S1 such as reading/writing of setting parameters or retrieving stored data. Function group IEC presents the following parameters, measured values and signals: Configuration Parameters IEC: Function group IEC 056 059 Canceling function group IEC or including it in the configuration. If the function group is canceled from the configuration, then all associated settings and signals are hidden. IEC: General enable USER 104 000 Enabling and disabling function group IEC. IEC: Enable configuration 104 058 This parameter can only be sent individually. In order to maintain consistency of all parameters in function groups IEC, GSSE and GOOSE, they are only enabled mutually by this parameter. After this command is sent to the device, the actual state of the previously changed parameter setting of the three function groups is enabled in the communication data model of the connected device. This function is carried out automatically with the off-line/on-line switching of the device. IEC: Inactivity timer 104 050 Additional communication monitor at Ethernet. Should a logged-on client issue no further request message after this time period has elapsed, this client will automatically be logged-off, i.e. no further reports will be issued to him. To re-establish communication the client is required to perform a new log-on procedure with the device (IED). IEC: Ethernet media 104 056 Selecting the physical communication channel on the Ethernet module from either wired (RJ45) or optical fiber (ST/SC connector depending on ordering option) connection. IEC: IED name 104 057 Name of the device (IED has server function). This device name serves as device identification in the IEC 61850 system, it is included in the Logical Device Name in the IEC data model and must therefore be unambiguous. All devices logged-on to the network should have non-recurring IED names. IEC: IP address 104 001 IP address for the device (IED has server function). IEC: Subnet mask 104 005 The subnet mask defines which part of the IP address is addressed by the sub-network and which part by the device that is logged-on to the network.

Such a configuration is required only then when this device must contact an external client/server direct without having its own network router to convert an IP address. Addressing of the router and the target network however are always necessary. Up to four such external target networks can be contacted. IEC: Router address 1 104 011 IP address of network router # 1. IEC: Target network 1 104 015 IP address of target network # 1. IEC: Router address 2 104 019 IP address of network router # 2.

IEC: Router address 4 104 035 IP address of network router # 4. IEC: Target network 4 104 039 IP address of target network # 4. IEC: SNTP operating mode 104 200 Operating mode for the time synchronization telegram. When set to Broadcast synchronization occurs cyclically with the clock server transmitting a broadcast signal and, when set to Request from Server each device (IED has client function) individually requests a synchronization signal after its own cycle time. IEC: SNTP poll cycle time 104 201 Device (IED) poll cycle time for time synchronization when operating mode is set to Request from Server. IEC: SNTP server 1 IP 104 202 IP address of the synchronizing clock server. IEC: SNTP server 2 IP 104 210 IP address of the synchronizing clock server. IEC: Diff. local time 104 206 Time difference between UTC and local time at the devices' substation (IED). IEC: Diff. dayl.sav. time 104 207 Time difference when changing to daylight saving time.
