SIPROTEC 5 Communication

SIPROTEC 5 devices are equipped with high-performance, pluggable communication interfaces and thus support optimal migration concepts in system modernizations. These interfaces are integrated or extendable via plug-in modules to offer a high degree of flexibility. The concept of plug-in modules and loadable protocols enables exchangeability and retrofitting.

USB connections on the front side

The device can be accessed with the operating program DIGSI 5 by plugging a standard USB cable into the USB-B socket on the front side of the base module. The complete configuration and setting of the device can be carried out via this pointto-point connection.

Integrated interfaces on the rear panel of the base module

The base module offers various, permanently installed interfaces on the rear panel. For even greater flexibility, 2 slots are available for plug-in modules. For this, please observe the connection plans in the attachment.

Integrated Ethernet interface (RJ45)

This electrical RJ45 interface serves to connect DIGSI 5 via a local Ethernet network. In this way, several devices can be operated from DIGSI 5 via one external switch. DIGSI 5 detects the devices even without an IP configuration on the local network and can then assign them IP addresses. Optionally, the protocol IEC 61850 can be activated on this interface for connections up to 6 clients. With the 7Sx82 devices and SIPROTEC 5 with CP300, GOOSE messages are also supported on this interface.

Time Synchronization Interface (D-sub 3)

Via the 9-pole D-sub socket (connection compatible with SIPROTEC 4), the time in the device can be synchronized. The set clock telegram IRIG-B005 (007) of a GPS receiver can be fed with 5 V, 12 V or 24 V levels. In addition, the Central European DCF77 format with summer and winter time changes is supported. An additional, second pulse input enables microsecond precise synchronization of the device from a highly precise time source, for example a special GPS receiver. This accuracy is needed for special protection and measuring tasks. In this way, devices can be precisely synchronized to the microsecond across stations. For this, Siemens provides a pre-fabricated complete solution with time receiver, optical fiber converters and appropriate connecting cables.

Connecting a detached operation panel (D-sub 15)

A detached operation panel provided together with the connecting cable can be connected to this interface. The maximum distance is 2.5 meters or 5 meters.

Connecting the expansion unit CB202 (RJ45)

The base module offers slots for 2 plug-in modules. If more plug-in modules are needed, these can be provided via a special expansion module CB202. This module is connected via RJ45. The expansion module is delivered with an appropriate cable and is connected with RJ45 on the base module. The CB202 has its own wide-range power supply unit. A great advantage here is that the switch integrated in an Ethernet module can execute its data forwarding function for neighboring devices even if the power supply of the base device is switched off, provided the CB202 is still powered. Thus, an Ethernet ring is not broken when one device is in service.
