3 Functional description
3.1 Basic set-up of the USM
The series of universal fault annunciators USM is designed for systems networked by Ethernet.
The USM serves for acquisition and indication of alarms that are provided on the galvanic inputs or
through the Ethernet interface from a communication partner (e.g. SCADA system). The alarms are
processed and displayed according to the parameterized reporting sequence.
The fault annunciators are available with 8, 16, 24, 32, 40 or 48 signal inputs. The alarms are aligned
to groups of 8 inputs each on the device front. The closed front panel contains 4 push buttons, bi-
colour LED displays (red / green) and slide-in pockets for the labelling strips. Each fault annunciator
features an internal horn. Additionally, an external horn can be triggered through a function relay.
The annunciator features four change-over relays as integrated function relays. Alarm specific
functions (e.g. collective report or external horn triggering) as well as signalization of any malfunction
through a live-contact can be realized with the function relays.
Two function inputs are available and can be used according to the chosen reporting sequence (e.g.
for external acknowledgement).
The functions that are assigned to the push buttons, function inputs and function relays can be
parameterized individually.
All USM fault annunciators provide a hardware-watchdog and software-monitoring. The fault-free
operation is indicated by an OK-LED and through a relay contact (live-contact).
The parameterisation of the annunciator is done through the integrated web-server with a web-
browser and by uploading of parameterization files. By these means the reporting sequence, input
processing, assignment to collective reports and horn triggering can be defined and protocol
parameters, IP-address and information object addresses can be parameterized. A detailed
descripition of the parameterization can be found in the section “Parameterisation”. Customised
special reporting sequences can be realized ex-factory upon request.
The fault annunciator USM provides different interfaces (USB, CAN, SDP, COM and LAN), which will
be described regarding functionality and usage in the following sections.
3.2 Internal Relays cards (optional)
The optionally integrated relay cards (8 NO contacts each) are independent from the 4 function relays
of the annunciator and can be assigned the following functions:
1. In- or output parallel multiplication and forwarding of single alarms within the annunciator and
without the requirement for connection of external relay modules MSM-RM.
2. Issue of collective reports and triggering of external horn
3. Triggering of the relay from the IEC interface
The 8 relays of one board have one common root. Triggering and functionality can be adapted
individually by means of the parameterization interface on the web-server, e.g. inversion of the signal
or wipe duration for pulse commands.
Additional explanations to the integrated alarm sequeces can be found in the
separate document „Alarm sequences of EES-Fault annunciators“(SM-MA-ZI-UK).

Functional description
Page 10 of 46 MSM-USM2G-BA-UK-001
3.3 Dual power supply (optional)
Independent from the primary power supply, a second, redundant power supply can be integrated into
the fault annunciator. Two different voltage variants are available:
24 –60 V AC/DC
110 –220 V AC/DC
The voltage level of the redundant power supply can be chosen independently from the voltage level
of the primary power supply. Both primary and secundary power supply are integrated into the self-
monitoring of the annunciator and any malfunction is indicated on the live-contact. Additionally,
presence of the supply voltage is indicated for both power supplies by an LED on the rear of the
device. Failure of one of the power supplies is communicated on the protocol interface.
3.4 Cascading of several fault annunciators
With the cascading functionality one USM and up to three BSM (BSM-C or BSM-P) can be grouped to
an annunciating system which is processed as a virtual compound annunciator with common
signalling (reporting sequence, forming of collective reports and horn triggering). Through the
communication interface of the USM, signals and alarms of the whole annunciating system can be
addressed.
The communication within the annunciating system is done through the integrated CAN-Bus interface.
The devices are connected to each other by means of a patch-cable. The USM works as “master” and
the connected BSM-C or BSM-P act as “slave”. Thus a system with up to 192 (4*48) signals can be
realized. When creating an annunciating system, please note that the number of channels of the USM
has to be bigger or equal to the number of channels of the connected BSM devices.
External MSM relay modules cannot be connected to cascaded annunciators.
Fig. 3.1: General design of a cascaded fault annunciator system
The parameterization is done in the master fault annunciator by means of the web-
server and is distributed automatically to the slave devices.
Information to the BSM annunciators can be found in the separate BSM manual.

MSM-USM2G-BA-UK-001 Page 11 of 46
Fig. 3.2: Examples of cascaded annunciator systems
3.5 Protocol interfaces
For communication to superior or inferior systems (e.g. SCADA or PLC) the USM provides one or two
interface cards. These contain the following interfaces:
Through these interfaces the fault annunciators can communicate to third party systems via the
following protocols:
IEC 60870-5-101 (USM is IEC-Slave)
IEC 60870-5-104 (USM is IEC-Server or Client)
IEC 61850 (USM is IEC-Server)
Card 1 (always equipped)
1 x Ethernet / RJ45
1 x RS232 / pluggable terminal
2 x USB-A
1 x CAN-Bus / RJ45
1 x USB-B (factory interface)
Card 2 (optionally equipped)
1 x Ethernet / RJ45 or
LWL SC-Type
1 x RS232 / pluggable terminal
As IEC-Server or Slave, the fault annunciator can establish connections to a
maximum number 4 Clients (Multilink). The combination of multiple of the above
mentioned protocols within one annunciator is possible.
As IEC-Client, the annunciator can establish IEC 104 connections to a maximum
number of 32 servers.

(IEC-Server/Slave) with an IEC-Client/Master.
3.6 Protocol IEC 61850 (optional)
In automated substations information from field- and protection devices are transmitted through the
protocol IEC 61850.
In addition, various specific single point alarms are available which –depending on the type of
information –need to be transmitted to the SCADA system or to other devices on field or station level.
The annunciators adopt this “rag-man“functionality and provide these single point information on the
integrated IEC 61850 server.
Individual reports and datasets can be configured easily which contain all relevant information about
the alarm and device status.
The IEC 61850 communication can be enabled in every USM by means of a license key.

3.7 IT security functionalities (optional)
For companies in the energy business a whitepaper with fundamental security measures for control
and telecommunication systems has been released. Goal of these measures is to provide an
appropriate protection against security threats in daily operation.
The security measures defined in this whitepaper are recommended for all new control or
telecommunication systems.
The strategic goal of the whitepaper is a positive impact on the product development for the
aforementioned systems with regard to IT security and to provide a common understanding for
protection of these systems.
Software options are available for annunciators of the series USM, which ensure that the devices can
be included into critical infrastructures under consideration of the recommendations of the
aforementioned whitepaper.
For detailed information on the IT security functionalities, please refer to the separate documentation

3.10 Diagnosis
For monitoring and evaluation of the system functions different diagnosis information are available.
These are e.g. the signalling of errors on watchdog LEDs or relay contacts or the provision of error
information on the protocol interface by means of the data object “error”.
3.10.1 Watchdog-LED „Self-monitoring“
The watchdog-LED „self-monitoring“ gives information about the current status of the annunciator
device or system:
Steady light green = no error
Flashing green (no flashing sequence) = initialisation of the annunciator
Flashing green (with flashing sequence) = annunciator in dedicated operation mode
Flashing red = error
Off = no power supply
From the flashing sequence, an error code can be read which defines the error. A flashing sequence
consists of:
Number of long flashing pulses 1st digit of the error code
Number of short flashing pulses 2nd digit of the error code
Pause
Example: long, short, short, pause = error code 12
In this section, the USM with 8 alarm channels is used to illustrate the general setup
of a USM. The number of signal inputs and the colours of the alarm LEDs can
deviate depending on the configuration and size of the respective USM.
If multiple errors are at issue, the LED displays the error with the highest priority.

3.10.2 Error codes
The hexadecimal error codes which are listed in the following table resemble the flashing sequence of
the OK-LED of the USM. If the error code is transmitted through the protocol interface, it might –
dependent from the superior system –be interpreted as decimal number.
