Preface

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.

1.1 General

1.1

General

With the EN100+ module firmware Modbus TCP from version V1.00, the Modbus TCP protocol is imple­mented in addition to other transmission protocols (e.g. IEC 61850 and GOOSE, see chapter 1.5.2) in the
100 Mbit Ethernet module EN100+.

NOTE

You can find all information about supporting the ModbusTCP protocol in the SIPROTEC 4 device manual.

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:

Application

The application Communication shows an example of the SIPROTEC 4 devices with Modbus TCP and
GOOSE. Modbus TCP is used for communication to a substation controller and GOOSE is used for inter­device data exchange.

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
