Windows Standard Embedded 7 User’s Guide for Eaton XP-503 with Visual Designer

Windows Standard Embedded 7 User’s Guide for Eaton

XP-503 with Visual Designer

Introduction

The Eaton XP-503 family is made up of high performance

yet cost-effective, wide-screen, multi-touch operator

interface (OI) products. The XP-503 family carries on Eaton’s

operator interface tradition of high performance balanced

with ease of use. The XP-503 family sets the standard for

hybrid OI systems by combining the flexibility of Microsoft

Windows Standard Embedded 7 operating system with

the stability and reliability achieved through a solid-state

hardware design and Eaton’s exclusive Protect Mode

feature that provides protection for unwanted changes to

the operating system and software.

The XP-503 family provides the performance and flexibility

of PC-based operator interfaces without the associated

complexity and maintenance of a PC on the plant floor.

With integrated high-speed Ethernet ports, serial ports,

USB ports, DVI-output, and removable C-Fast solid-state

memory, the XP-503 models can be adapted for a wide

variety of user requirements.

The XP-503 family of products configured with the Visual

Designer software provides a range of solutions from

basic operator monitor and control functions to full SCADA

software capabilities with built-in Web Serving.

Whether replacing hard-wired pilot devices and pushbuttons

or providing machine control and high-end SCADA functions,

the XP-503 will suit a wide range of user requirements.

The remainder of this document describes some of the

operating system features of the XP-503 system.

Eaton FP-4000 Application Description

Application Description

Eaton’s Cutler-Hammer FP-4000 Feeder Protection Relay provides

complete 3-phase and ground overcurrent and voltage protection

plus metering. It may be used as primary protection on feeders, mains

and tie circuit breaker applications, and as backup protection for trans

formers, high voltage lines and differential protection. The relay is most

commonly used on medium voltage switchgear applications.

The FP-4000 takes full advantage of its microprocessor technology,

providing the user new freedoms and a wealth of data-gathering

features. The relay performs self-checking of all major hardware and

firmware protection elements to ensure their operation in the event of

a system or component electrical failure or fault. Protection functions

are well suited for main and distribution feeder circuit applications.

Programmable logic control functions make the FP-4000 relay ideally

suited for main-tie-main and main 1/main 2 transfer schemes.

The zone interlocking feature can be utilized for bus protection instead

of an expensive and complicated bus differential (87B) scheme.

The FP-4000 works directly with the Cutler-Hammer Digitrip 3000

and Digitrip MV relays. New breaker failure logic provides faster

remote backup clearing times for stuck breaker operation.

The FP-4000 provides trip and close circuit monitoring and alarming

features. It continually monitors the complete trip and close circuits

for continuity and readiness to trip. Open and close pushbuttons are

conveniently located on the front of the relay for local breaker operation.

Loss-of-vacuum monitoring is activated when the breaker is open.

Residual current is monitored and alarmed if detected.

When an electrical fault or disturbance occurs, the FP-4000 begins

to store the following in non-volatile memory:

• Voltage and current sampled data.

• Calculated values.

• Status of internal protection functions, logic, contact inputs and

outputs.

Retrieval and viewing of the data is easy, aiding in the quick analysis

and restoration of your electric power system.

Eaton’s Cutler-Hammer FP-4000 Feeder Protection Relay

FP-4000 Product Description

• Microprocessor-based protection with monitoring and control for

medium voltage main and feeder breakers.

• Current, voltage and frequency protection for electric power

distribution systems.

• Complete metering of voltage, currents, power, energy,

minimum/maximum and demand functions.

• Programmable logic control functions for main-tie-main

transfer schemes.

• Trip logs, event logs and waveform capture for better fault analysis

and system restoration.

• Data Logger to provide energy usage profiles for better planning,

utilization and energy usage.

• Fixed case design.

• Meets ANSI and UL standards.

When the FP-4000 isn’t responding to disturbances in the power

system, it’s providing valuable metering information at the relay and

remotely. It provides energy usage and demand reading, and can

alarm when usage reaches a set value. Power factor measurements

can be used for cap bank switching to control kvar demand.

Onboard data trending can provide load profiles for up to 40 days.

The protection functions are listed below and shown in Figure 1.

The FP-4000 provides phase overcurrent:

• Two-stage instantaneous with timers (50P-1 and 50P-2).

• Inverse time overcurrent (51P-1).

• 10 standard curves.

• Instantaneous or time delay reset.

CTI 2500P-JACP Janus Application Coprocessor

The 2500P-JACP Janus Application Coprocessor is a general-purpose auxiliary

controller that enhances the capabilities of all CTI 2500 Series® and SIMATIC®

505 PLC systems. This Advanced Function Module is based on Janus technology

and includes high-speed processing and multi-protocol communications support

to provide existing systems with a significant increase in performance, features,

and functionality.

Because of its broad communications capabilities and ability to store large amounts

of data on-board, the 2500P-JACP is ideal for Edge Computing applications, bringing

computation and data storage closer to the location where it is needed, to improve

response times and save bandwidth.

The 2500P-JACP runs as a PLC coprocessor performing complex logic/math functions,

data logging, and communications with external devices. Although the 2500P-JACP

can operate as a standalone controller, the control application generally requires data

transfer between a host PLC and the module. Two different data transfer options are

provided:

Block Transfer Driver: The 2500P-JACP enables the user to configure the Block Transfer

Driver which optimizes the exchange of up to 2048 data points with a Siemens, TI, or

CTI PLC using the special function I/O backplane protocol. The application can select to

exchange V, X/Y, WX/WY, or Control Relays for continuous Read or Read/Write.

Note this feature allows the 2500P-JACP to be used with existing Simatic/TI 545 and

555 PLCs.

Data Cache: Proprietary link offering enhanced data throughput to CTI 2500 Series®

controllers via a dedicated Ethernet connection. Supports up to 6144 variables mapped

to any PLC memory type (including Loop/Alarm variables). 

The 2500P-JACP includes two external 10/100/1000Mb Ethernet ports with automatic

detection of network speed, duplex mode, and cable wiring. An aliasing and isolation

feature allows the two network ports to exist on two separate networks, a useful feature

for isolating networks of drives or other I/O devices from the main plant communications

network.

• Enables PLC logic to monitor status and control switchover, if desired.

• Allows optional manual switchover capability

• Uses high-reliability relays to directly connect the active PLC and remote

I/O without intervening

electronics.

• Defaults to a user-defined switched position on power loss or hardware

failure

CTI 2541 Redundant Processor Manager Module

The 2541 Redundant Processor Manager (RPM) provides an automatic

backup solution for 2500 Series® PLCs. If the active PLC fails, the RPM

will automatically switch the remote I/O to the standby PLC.

Transfer to the standby PLC is bumpless. All remote I/O updates are

mirrored to the standby PLC. In addition, up to 4096 words of user-

defined critical data can be transferred from the active PLC to the 

standby PLC every scan.

Other non-critical data can be transferred over several scans.

The RPM can also switch up to two serially attached operator interface

devices.

IMPORTANT NOTE: Due to extensive component obsolescence issues

and insufficient demand to justify a re-engineering effort, this product

has been matured.  For users needing PLC redundancy in the future,

we have a solution planned based on our new Janus Programmable

Automation Controller which uses two Janus PLCs and a Modbus relay

that switches Remote I/O and Profibus networks from the primary PLC

to the backup in case of a Processor failure.
