Siemens 6SE7090-0XX84-0BC0 SIMOREG DC-MASTER SCB1 Serial Communication Board
The SIMOREG option board that operates as the master for SCI1 and SCI2 serial communication interfaces through the documented fiber-optic link.
Overview
6SE7090-0XX84-0BC0 is Siemens Serial Communication Board 1 for the SIMOREG DC-MASTER platform. Siemens identifies SCB1 as the master for SCI1 and SCI2, with the interface stations connected through fiber optics.
The board belongs to the converter option architecture. Its installed slot, companion SCI interfaces, fiber route, converter order number and parameter record therefore form one service boundary; the part number alone does not establish a complete replacement plan.
Specifications
Features
Central serial coordination
Acts as the master board for the two published SCI interface types.
Fiber-linked interface path
Separates the remote interface stations from the converter electronics through the specified optical link.
Option-board integration
Operation depends on the approved SIMOREG board arrangement and host converter configuration.
Topology-aware maintenance
Station identity and cable routing remain visible throughout removal and recommissioning.
Applications
Remote serial interface expansion
Connecting documented SCI1 or SCI2 interface stations to a SIMOREG DC drive.
Legacy drive communication service
Restoring an installed SCB1 communication path without changing the approved topology.
Controlled spare qualification
Comparing a replacement against converter, slot, interface and parameter records.
Lifecycle
Capture
Back up parameters and photograph the SCB1 label, host converter, slot and every optical connection.
Exchange
De-energize the converter electronics, preserve fiber orientation and install only the verified board execution.
Validate
Confirm each SCI station, serial traffic, fault response and converter operation against the approved record.
FAQ
Q01
What evidence should accompany a 6SE7090-0XX84-0BC0 enquiry?
+
Provide the full board label, converter MLFB and serial number, installed slot, SCI1/SCI2 station labels, fiber routing and requested quantity.
Q02
Does 6SE7090-0XX84-0BC0 operate as a stand-alone serial interface?
+
No. Siemens defines SCB1 as the master for connected SCI interface stations within the SIMOREG option architecture.
Q03
Why must the fiber path be recorded before removing 6SE7090-0XX84-0BC0?
+
The station relationship and connection direction are part of the communication topology and cannot be reconstructed safely from the board label alone.
Q04
Can another SIMOREG communication board replace 6SE7090-0XX84-0BC0 because it fits the electronics box?
+
No. Mechanical fit does not establish the same serial-master function, interface support or converter configuration.
Q05
What proves 6SE7090-0XX84-0BC0 is ready after replacement?
+
Retain clean diagnostics, successful communication with every required SCI station, correct timeout behavior and stable converter operation.
