Microcomputer
System The control functions and the measurement quantities are processed in the microcom- puter system µC. They especially consist of:
• Control of command outputs,
• Decision for close commands,
• Processing of indication inputs,
• Storage of annunciations, fault data and fault values for fault analysis,
• Control of signals for logical functions,
• Filtering and conditioning of the measured signals,
• Continuous monitoring of the measured quantities
• Monitoring the communication with other devices,
• Querying of limit values and time sequences,
• Management of the operating system and the associated functions such as data
recording, real-time clock, communication, interfaces, etc.
Analog inputs
(optional) The measuring inputs (ILx, Vx) convert the currents and voltages coming from the
transformers and adapt them to the level appropriate for the internal processing of the
device. The device has 3 current and 4 voltage inputs.
The current and voltageinputs can be used separately for measured value acquisition.
Within the scope of configuration, one- or three-phase evaluation functions are avail-
able for evaluation of the analogue inputs and evaluation after the Aron connection.
With voltage inputs, both phase-earth and phase-phase voltages can be applied. In
addition to a three-phase system, another reference voltage for synchronisation tasks
or a displacement voltage Vncan be measured via the fourth voltage input.
Furthermore, two measuring transducer inputs are available.
The analogue values are transferred further to the IA input amplifier group.
The input amplification IA stage provides high-resistance terminations for the ana-
logue input quantities. It consists of filters that are optimised with regard to bandwidth
and processing speed.
The analogue-to-digital (AD) stage consists of a multiplexor, an analogue-to-digital (A/
D) converter and memory components for the transmission of digital signals to the
microcomputer system.
Binary Inputs and
Outputs Binary inputs and outputs from and to the computer system are routed via the I-/O modules (inputs and outputs). The computer system obtains the information from the
system (e.g remote resetting) or the external equipment (e.g. blocking commands).
Outputs are, in particular, commands to the switchgear units and indications for
remote signalling of important events and statuses.
Front Elements With devices with integrated or detached operator panel, information such as mes-
sages related to events, states, measured values and the functional status of the
device are provided via light-emitting diodes (LEDs) and a display screen (LCD) on
the front panel.
Integrated control and numeric keys in conjunction with the LCD facilitate local inter-
action with the device. Via these elements all information of the device such as con-
figuration and setting parameters, operating messages and measured values can be
accessed. Setting parameters may be changed in the same way.
In addition, control of circuit breakers and other equipment is possible from the front
panel of the device.

Serial Interfaces A serial PC interface is provided for local communications with the device through a
personal computer using the operating program DIGSI®. This permits convenient
operation of all functions of the device.
A separate Service Port can be provided for remote communications via a modem, or
substation computer using DIGSI®4. This port is especially well suited for the fixed
wiring of the devices to the PC or operation via a modem.
Via the serial system interface all device data can be transferred to a central evalua-
tion unit or to a control center. This interface may be provided with various protocols
and physical transmission schemes to suit the particular application.
Communication with other SIPROTEC®4 devices which also have inter relay commu-
nication can occur via the serial interface to the (optional) on the device rear. Com-
munication is achieved regardless of the connection to the central device SICAM SAS
and a redundancy to the system interface.
A further interface is provided for the time synchronization of the internal clock via
external synchronization sources.
Further communication protocols can be realised via additional interface modules.
Process bus inter-
face The process bus interface allows a direct communication with SICAM HV modules. It is equipped with an Ethernet module.
Power Supply The before-mentioned function elements and their voltage levels are supplied with
power by a power supplying unit (Uaux or PS). 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).

1.2 Applications
The SIPROTEC®Bay Processing Unit 6MD665 is an integrated part of the SICAM
power automation system. Command outputs and indication inputs are especially
adapted to the requirements of high-voltage technology.
By means of appropriately equipped switchgears the Bay Processing Unit can com-
municate with the SICAM HV modules via a process bus. Therefore the system is also
called an intelligent switchgear bay. The SICAM HV modules are not suitable for all
types of switchgears. Detailed information can be obtained from your local Siemens
sales representative.
When connecting the circuit breaker, the Bay Processing Unit can check if the syn-
chronisation conditions of the two subnetworks to be combined are met (synchro-
check). This makes the use of an additional external synchronisation device unneces-
sary. The synchronisation conditions can be configured conveniently with the DIGSI®
operating program. The device distinguishes between synchronous and asynchro-
nous networks and reacts differently on the connection.
Control functions The device provides a control function which can be accomplished for activating and
deactivating switchgears via integrated operator panel, system interface, binary
inputs, and the serial port using a personal computer with DIGSI®.
The status of the primary equipment can be transmitted to the device via auxiliary con-
tacts connected to binary inputs. The present status (or position) of the primary equip-
ment can be displayed on the device, and used for interlocking or plausibility monitor-
ing. The number of the operating equipment to be switched is limited by the binary
inputs and outputs available in the device or the binary inputs and outputs allocated
for the switch position indications. Depending on the primary equipment being con-
trolled, one binary input (single point indication) or two binary inputs (double point indi-
cation) may be used for this process.
The capability of switching primary equipment can be restricted by a setting associ-
ated with switching authority (Remote or Local), and by the operating mode (inter-
locked/non-interlocked, with or without password request).
Processing of interlocking conditions for switching (e.g. system interlocking) can be
established with the aid of integrated, user-configurable logic functions.
Messages and Mea-
sured Values The operating messages provide information about conditions in the power system and the device. Measurement quantities and values that are calculated can be dis-
played locally and communicated via the serial interfaces.
Device indications can be assigned to a number of LEDs, externally processed via
output contacts, linked with user-definable logic functions and/or issued via serial
interfaces.
Communication For communication with external operator and control systems and Inter relay commu-
nication, serial interfaces are available.
A 9-pole DSUB socket on the front cover ensures the local communication with a per-
sonal computer. By means of the SIPROTEC®operating software DIGSI®4, all oper-
ational and evaluation tasks can be executed via this user interface, such as specify-
ing and modifying configuration parameters and settings, configuring user-specific
logic functions, retrieving operational messages and measured values, inquiring
device conditions and measured values, issuing control commands.

Depending on the individual ordering variant, additional interfaces are located on the
rear side of the device. They serve to establish an extensive communication with other
digital operating, control and memory components:
The service interface can be operated via electrical data lines or fibre optics and also
allows communication via modem. For this reason, remote operation is possible via
personalcomputer and the DIGSI®operating software, e.g. to operate several devices
via a central PC.
The system interface ensures the central communication between the device and the
substation controller. The service interface can be operated through data cables or
fibre optic cables.
The device has a field bus coupling with PROFIBUS FMS. The PROFIBUS FMS
according to DIN 19 245 is an open communication standard with particularly wide
acceptance in process control and automation engineering, with especially high per-
formance. A profile has been defined for the PROFIBUS communication that covers
all of the information types required for process control engineering. The integration of
the devices into the power automation system SICAM®can also take place with this
profile.
In addition, standardised protocols in accordance with IEC 60 870-5-103 are available
for data transmission. The integration of the devices into automation systems from
other manufacturers can also take place with this profile.
Optionally, you can use an additional serial interface for Inter relay communication. It
takes over communication with other SIPROTEC®4 devices, regardless if the device
is connected to the control center.
The process bus interface allows a direct communication with SICAM HV modules.
They communicate process data between the Bay Processing Unit and the device
control (of circuit breakers, disconnectors and ground switches). Here, a PCU (Pro-
cess Communication Unit) serves as a communication link between controller and
process bus.
