Chapter 1 Introduction
1.1 Application
RCS-9698G/H, a remote terminal unit (RTU) is designed for the highest standards of performance,
safety and reliability to meet requirements of a complex substation automation system (SAS). It is
an integral part of the RCS-9700 SAS, and it is a communication gateway that maps signals
between protection and control IEDs in industrial or utility substations and higher-level systems
such as Network Control Centers (NCC) or Distributed Control Systems (DCS).
RCS-9698G/H sends information for monitoring and controlling process to a NCC and DCS and
receives process control commands from them.
RCS-9698G/H is based on a robust industrial hardware rather than on PC technology. The
modular design enables it to be configured freely to fulfill the communication requirements of a
particular application (physical interfaces, protocols etc.). The architecture is designed for parallel
processing and multi-protocol operation. Some standardized protocols, such as
IEC60870-5-101/IEC60870-5-104, for linking of systems from other suppliers ensures the
openness of the system.
Single mode or redundant mode of the RTU can be chosen according to its engineering
requirements. RCS-9698G works in the single mode and the RCS-9698H works in the redundant
mode.
A typical application ofRCS-9698H in a certain RCS-9700 SAS is shown as below.

meet the requirements of the user.
Automatic clock synchronization and unified system timing can be realized via GPS. Able to
receive and deal with IRIG-B signals, pulse per second (PPS) signals, timing messages and
SNTP clock synchronization.
Monitoring the communication status of the IEDs.
Multi-scheme for dual monitoring and automatic switchover.
LCD display to view real database, to set run scheme and parameters.
Online maintenance and monitoring via network by convenient tools:
RCS-9798 Configuration Tool and RCS-9798 Debugging Tool.
Self-diagnosis.
RCS-9698G/H can monitor its software and hardware during operation. Alarm signals will be
issued if any software and hardware errors occur. At the same time, RCS-9698G/H will lock
itself to avoid unwanted operation.
When errors occur in the master side of RCS-9698H, besides the master side locks itself, the
slave side can run in master mode automatically, and then issue signals to ensure the
stability and the reliability.
