1 Overview
Version Changes
P433-305-406/407-610 Hardware The new Ethernet module for communication per IEC 61850 is now
P435-305-407/408/409-610 available and may be fitted to slot 2 as an alternative to communication
module A.
Release: 20.02.2006
Diagram The updated connection diagrams now include the Ethernet module
communication interface.

The designation of the binary inputs and output relays have been
replaced by the standard Px3x texts, i.e. the designation comprises the
board location number (1 or 2 digits) followed by a consecutive number
(2 digits).
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).

2 Functional Details
2.1 Communication Interface IEC 61850 (Function Group IEC)
As a further option the P433/P435 now includes an interface protocol according to the
Ethernet based communication standard IEC 61850.
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.

Ethernet Module
The optional Ethernet module provides an RJ45 connection and a fiber optic interface
where an Ethernet network can be connected. 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.

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.

Communication with the
Operating Program
MiCOM S1 via the Ethernet
Interface
Direct access by the operating program MiCOM S1 via the Ethernet interface on the
device may occur through the "tunneling principle". 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.

IEC: Number of routes 104 010
Number of network routes, that can be contacted outside of the sub-
network, between the device (IED) and a client or server, communicating
with this device, and situated in an exterior target 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: Target network 2 104 023
IP address of target network # 2.
IEC: Router address 3 104 027
IP address of network router # 3.
IEC: Target network 3 104 031
IP address of target network # 3.
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.

IEC: Deadband value 104 051
Setting to calculate the filter value for all measured value Report Control
Blocks (RCB) except the measured value for energy. Should a change
occur in one of the measured values, which is greater than the filter value,
the RCB is again sent to all clients. For each measured value the filter
value is calculated according to this formula:
Step size measured value • setting IEC: Deadband value
IEC: Update cycle energy 104 060
Cycle time to send energy value by Report Control Block (RCB). No RCB
transmission with setting to blocked!
