who can demonstrate technical qualifications as electrical technicians. These persons may commission,
isolate, ground and label devices, systems and circuits according to the standards of safety engineering.
Proper Use
The equipment (device, module) may be used only for such applications as set out in the catalogs and the
technical description, and only in combination with third-party equipment recommended and approved by
Siemens.
Problem-free and safe operation of the product depends on the following:
•Proper transport
•Proper storage, setup and installation
•Proper operation and maintenance
Preface
4 SIPROTEC 4, Modbus TCP Profile, Manual
C53000-L1840-C582-1, Edition 07.2015

When electrical equipment is operated, hazardous voltages are inevitably present in certain parts. If proper
action is not taken, death, severe injury or property damage can result:
•The equipment must be grounded at the grounding terminal before any connections are made.
•All circuit components connected to the power supply may be subject to dangerous voltage.
•Hazardous voltages may be present in equipment even after the supply voltage has been disconnected
(capacitors can still be charged).
•Operation of equipment with exposed current-transformer circuits is prohibited. Before disconnecting the
equipment, ensure that the current-transformer circuits are short-circuited.
•The limiting values stated in the document must not be exceeded. This must also be considered during
testing and commissioning.

General
With the EN100+ module firmware Modbus TCP from version V1.00, the Modbus TCP protocol is imple-
mented in addition to other transmission protocols (e.g. IEC 61850 and GOOSE, see chapter 1.5.2) in the
100 Mbit Ethernet module EN100+.
i
i
NOTE
You can find all information about supporting the ModbusTCP protocol in the SIPROTEC 4 device manual.
i
i
NOTE
The required settings are made using the DIGSI 4 V4.90 and higher.
For the configuration of Modbus TCP a DIGSI 4 packet is required with IEC 61850 station configurator.
You can find detailed information on the EN100+ module and the IEC 61850 engineering in the following
manuals:
German edition: Ethernetmodul EN100+, Handbuch Bestellnr. C53000-G1100-C167
US-English edition: Ethernet Module EN100+, Manual Order no. C53000-G1140-C167
In the following text, the following abbreviations are used:

NOTE
The settings above are valid for all Modbus TCP connections in the same way; they cannot be configured
individually for each Modbus TCP connection or for each connected Modbus TCP master..
During startup of the Ethernet module, the configuration of all Modbus TCP parameters is checked. If a
parameter value is detected outside the valid range, an error-log entry is issued on the EN100+ module
and the parameter is set to its default value (see
Figure 5-2 ).
