Firmware versions Two firmware versions V03 and V04 are available for the SICAM P 7KG7750/55
device which
•offer identical basic functionality,
•differ in the supported communication protocols (refer to Table 1-1),
•can be loaded alternatively in the SICAM P 7KG7750/55. 1)

Note:
For using the IEC 60870-5-103 protocol a SICAM P 7KG7750/55 device with firmware
V04 is necessary
The use of the IEC 60870-5-103 communication protocol and configuration software
“SICAM P Parameterization” up to V01.30 is limited to SICAM P 7KG7750/55 devices
with integrated display (7KG7750) because of additional communication parameters
(refer to chapter 1.2).

Identification of the
firmware version
The current firmware version of your SICAM P 7KG7750/55 can be identified as fol-
lows:
•Read the device identification using the software “SICAM P Parameterization” as
described as preparation for a firmware update in the Application Description “Firm-
ware Update” (refer to page 3 for the order number of this document), e.g.:
•Devices with integrated display (7KG7750):
−the firmware version is shown at the display after device start-up for 15 seconds,
e.g.:
−the menu “>settings” - “>about SICAM” can be selected which shows basic de-
vice data, e.g.:

1.2 Updating from V03 to V04
Firmware For using the IEC 60870-5-103 protocol a SICAM P 7KG7750/55 device with firmware
V04 is necessary (refer to Table 1-1).
If your SICAM P 7KG7750/55 has firmware V03 loaded then an update to firmware
V04 has to be executed.
Please refer to the Application description “Firmware Update” (refer to page 3 for the
order number of this document) for a step-by-step description of the firmware update
process.
Parameter set An existing SICAM P 7KG7750/55 parameter set used with firmware V03 can be used
furthermore with firmware V04.
The additional parameter MV range will be added automatically but must be set to the
required value during configuration of the IEC 60870-5-103 bus parameters (refer to
chapter 2.1).
SICAM P
Parameterization
V01.30
The version V01.30 of the software “SICAM P Parameterization” does not support the
IEC 60870-5-103 protocol configuration.
This has the following implications with SICAM P 7KG7750/55 V04:
•If in “SICAM P Parameterization” the protocol Profibus DP is selected (which is not
supported in SICAM P 7KG7750/55 firmware version V04) then in the device the
protocol IEC 60870-5-103 is set instead.
•The new parameter MV range can not be changed using “SICAM P Parameteriza-
tion”.
Therefore, the use of the IEC 60870-5-103 communication protocol and configuration
software “SICAM P Parameterization” up to V01.30 is limited to SICAM P 7KG7750/
55 devices with integrated display (7KG7750).
SICAM P
Parameterization
V01.40
Supports IEC 60870-5-103 communication protocol and configuration software

2.1 Bus Specific Parameters
2.1.1 General
The following settings for the serial communication between the IEC 60870-5-103
master and the IEC 60870-5-103 slave have to be defined during parameterization of
the SICAM P 7KG7750/55 device.
For parameterization of the bus specific parameters in SICAM P PAR from V1.40
please open the dialog box Device connection parameters (Fig. 2-1) using the menu
command:
Menu Device →Connection configuration →Edit.
Adjust the parameters in the dialog box Device connection parameters (Fig. 2-1):

Note:
The use of the IEC 60870-5-103 communication protocol and configuration software
“SICAM P Parameterization” up to V01.30 is limited to SICAM P 7KG7750/55 devices
with integrated display (7KG7750) because of additional communication parameters
(refer to chapter 1.2).

2.1.2 IEC 60870-5-103 Settings
Bus address Permissible bus addresses are in the range between 1 and 254.
Baud rate The following values for transmission speed are supported:
•9600 bit/s,
•19200 bit/s and
•38400 bit/s.
Parity Parity is adjustable to none, even or odd parity bit (N, E, O). The predefined parity acc.
to IEC 60870-5-103 specification is: E (even).
Note:
The screen is valid from firmware
version 4.10.

Note:
During the baud rate selection for IEC 60870-5-103 via “SICAM P Parameterization”
or via display the complete range from 300 bit/s to 115200 bit/s is offered.
But only 9600 bit/s to 38400 bit/s are permitted for IEC 60870-5-103.

Parameters and Properties

Protocol “IEC 103” selects the IEC 60870-5-103 protocol.
IEC 103 settings Open the screen acc. to Fig. 2-3 (from Version 4.10) with MV range, Harmonics and
Counters.
MV range An additional IEC 60870-5-103 parameter determines the end range of the transmitted
measured values via the protocol.
All measured values are transferred via IEC 60870-5-103 as per-unit values in two
octets which contain the measured values itself as 12 bits and an overflow as well as
an error indication bit.
The additional parameter now decides if the measured value ranges of -4096 to +4095
correspond either
•from -120 % to +120 % or
•from -240 % to + 240 %
of the nominal values.
Harmonics The transmission of harmonic is adjustable (yes or no), from version 4.10. See chap-
ters 3.1.2.5 and 3.1.2.6.
•yes: telegram function type 130, Information number 153 (1-phase) or
154 (3-phase) is transmitted
•no: no transmission
Counters The transmission of counters is adjustable (yes or no), from version 4.10. See chapter
3.3.2.
•yes: counters acc. to table 3-6 are transmitted
•no: not transmission
Note:
The screen IEC 103 settings also is offered if Modbus is selected as protocol, but then
does not have any effect.

2.2 Functional Range
This chapter describes the functional range which is supported by the IEC 60870-5-
103 slave interface of the SICAM P 7KG7750/55 device.
2.2.1 Basic Application Functions
Table 2-1 Basic application functions
Clock
synchronization
The accuracy of the internal clock of the SICAM P 7KG7750/55 with clock synchroni-
zation via IEC 60870-5-103 compared to the clock of the IEC 60870-5-103 master is
±100 ms.
The SICAM P 7KG7750/55 automatically calculates based on the start and end dates
configured for the parameter Clock Change if the current date is summertime (day-
light saving time) or not.
Therefore, the SU bit in the Time Synchronization message in control direction is
ignored by the SICAM P 7KG7750/55 device.
The SU bit in the Time Synchronization message in monitoring direction is set accord-
ing to the internal summertime recognition of the current date.
