Overview

The EX2100e Excitation Control Regulator system is GE’s most recent state-of-the-art

control system for steam, gas, or hydro generators for both new and retrofit units. Control

hardware and software design is closely coordinated between GE’s system and controls

engineering to ensure delivery of a true system solution. Integration is seamless between

Excitation Control systems, Turbine Control systems, Static Starter Control systems,

Integrated Control Systems (ICS), and the Human-machine Interface (HMI). For

stand-alone retrofit applications, integration with customer distributed control systems

(DCS) through serial or Modbus ® Ethernet is supported. This document specifically

addresses applications for the 35 A and 120 A (nominal) series of EX2100e Control

Regulator systems.

The EX2100e Regulator system supports Ethernet local area network (LAN)

communication to the following:

• Turbine controls and ICS, HMI, Proficy*-based Historian, Programming Interface

(PI-based) Historian, Onsite Monitoring System (OSM), and COI

• ExtendedI/O modules using the Ethernet Global Data (EGD) protocol

• CustomerDCSthrough Ethernet or Modbus Ethernet remote terminal unit (RTU)

• ToolboxST application

• GE OnsiteSupport for monitoring and diagnostics
