Safety Information

Important Information

Read these instructions carefully and look at the equipment to become familiar with the device before trying to install, operate, service or maintain it. The following special messages may appear throughout this manual or on the equipment to warn of potential hazards or to call attention to information that clarifies or simplifies a procedure.

The addition of either symbol to a “Danger” or “Warning” safety label indicates that an electrical hazard exists which will result in personal injury if the instructions are not followed.

This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death.

DANGER indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.

WARNING indicates a potentially hazardous situation which, if not avoided, can result in death or serious injury.

CAUTION indicates a potentially hazardous situation which, if not avoided, can result in minor or moderate injury.

NOTICE is used to address practices not related to physical injury. The safety alert symbol shall not be used with this signal word.

Please note

Electrical equipment should be installed, operated, serviced and maintained only by qualified personnel. No responsibility is assumed by Schneider Electric for any consequences arising out of the use of this material.

A qualified person is one who has skills and knowledge related to the construction, installation, and operation of electrical equipment and has received safety training to recognize and avoid the hazards involved.

Before you Begin

Do not use this product on machinery lacking effective point-of-operation guarding.

Lack of effective point-of-operation guarding on a machine can result in serious injury to the operator of that machine.

UNGUARDED MACHINERY HAZARD

• Do not use this software and related automation equipment on equipment which does not have point-of-operation protection.

• Do not reach into machinery during operation.

Failure to follow these instructions can result in death, serious injury, or equipment damage.

This automation equipment and related software is used to control a variety of industrial processes. The type or model of automation equipment suitable for each application will vary depending on factors such as the control function required, degree of protection required, production methods, unusual conditions, government regulations, etc. In some applications, more than one processor maybe required, as when backup redundancy is needed.

Only the user can be aware of all the conditions and factors present during setup, operation, and maintenance of the machine; therefore, only the user can determine the automation equipment and the related safeties and interlocks which can be properly used. When selecting automation and control equipment and related software for a particular application, the user should refer to the applicable local and national standards and regulations. The National Safety Council’s Accident

Prevention Manual (nationally recognized in the United States of America) also provides much useful information.

In some applications, such as packaging machinery, additional operator protection such as point-of-operation guarding must be provided. This is necessary if the operator’s hands and other parts of the body are free to enter the pinch points or other hazardous areas and serious injury can occur. Software products alone cannot protect an operator from injury. For this reason the software cannot be substituted for or take the place of point-of-operation protection.

Ensure that appropriate safeties and mechanical/electrical interlocks related to point-of-operation protection have been installed and are operational before placing the equipment into service. All interlocks and safeties related to point-of-operation protection must be coordinated with the related automation equipment and software programming.

NOTE: Coordination of safeties and mechanical/electrical interlocks for point-ofoperation protection is outside the scope of the Function Block Library, System

User Guide, or other implementation referenced in this documentation.

Start-up and Test

Before using electrical control and automation equipment for regular operation after installation, the system should be given a start-up test by qualified personnel to verify correct operation of the equipment. It is important that arrangements for such a check be made and that enough time is allowed to perform complete and satisfactory testing.

EQUIPMENT OPERATION HAZARD

• Verify that all installation and set up procedures have been completed.

• Before operational tests are performed, remove all blocks or other temporary holding means used for shipment from all component devices.

• Remove tools, meters, and debris from equipment.

Failure to follow these instructions can result in injury or equipment damage.

Follow all start-up tests recommended in the equipment documentation. Store all equipment documentation for future references.

Software testing must be done in both simulated and real environments.

Verify that the completed system is free from all short circuits and grounds, except those grounds installed according to local regulations (according to the National

Electrical Code in the U.S.A., for instance). If high-potential voltage testing is necessary, follow recommendations in equipment documentation to prevent accidental equipment damage.

Before energizing equipment:

• Remove tools, meters, and debris from equipment.

• Close the equipment enclosure door.

• Remove ground from incoming power lines.

• Perform all start-up tests recommended by the manufacturer.

Operation and Adjustments

The following precautions are from the NEMA Standards Publication ICS 7.1-195

(English version prevails):

• Regardless of the care exercised in the design and manufacture of equipment or in the selection and ratings of components, there are hazards that can be encountered if such equipment is improperly operated.

• It is sometimes possible to misadjust the equipment and thus produce unsatisfactory or unsafe operation. Always use the manufacturer’s instructions as a guide for functional adjustments. Personnel who have access to these

adjustments should be familiar with the equipment manufacturer’s instructions and the machinery used with the electrical equipment.

• Only those operational adjustments actually required by the operator should be accessible to the operator. Access to other controls should be restricted to prevent unauthorized changes in operating characteristics.

Twido WAGES D12, D28, D44 Gateway Solution

Introduction

Twido WAGES Overview

This guide describes a solution that combines a Twido programmable controller and an EGX300 Ethernet Gateway to process pulse information from water, air, gas, electricity, or steam (WAGES) field devices. The EGX300 makes pulse information available to a PC-based supervisory system such as StruxureWare

Power Monitoring (SPM) or to a remote monitoring service such as EnergyView

Online (EVO) or Remote Energy Management (REM). See Figure 1– 1 for data

flow in the Twido WAGES solution.

The EGX300 is an Ethernet-based device providing a transparent interface between Ethernet-based networks and field devices. Field devices include meters, monitors, protective relays and other devices that communicate using Modbus. In this document, field devices refers to WAGES meters.

The Twido accumulates pulses from the field device and provides a value scaled into units specific to each application (for example, gallons of water or cubic feet of gas). The EGX300 reads the scaled value from the Twido and stores historical trend information so you can derive average values over specified time intervals.

The user sets the scaling factor for each channel in the system through the PCbased supervisory system.

Device Logging

The EGX can log data received by the Twido PLC at predefined intervals (5, 10, 15,

20, 30, and 60 minutes). Below is an explanation of how the EGX logs data and how to set up logging for a device.


63220-095-04A1

12/2012

Interval Data Logging


EGX300 Setup

Many devices in a power monitoring system do not have the ability to record data in non-volatile memory. The EGX300 provides this data logging at predefined intervals for up to 32 serially connected devices. The EGX stores the recorded data in non-volatile FIFO (First In First Out) files.

The logging capacity for each data-log file is variable and dependent on the selected logging interval. Logging capacity of each data-log file can be calculated by dividing the maximum possible number of recorded intervals a data-log file can contain (171,072) by the product of the number of topics logged and the intervals recorded per day.

Log File Capacity = Intervals (max) / (topics per interval * intervals recorded per day)

For example, the logging capacity for a device data-log recording three topics every

10-minutes would be determined as follows:

Intervals Recorded Per Day = Minutes per day / Logging Interval (in minutes)

= 1440 / 10

= 144 intervals

Log File Capacity = Maximum Possible Intervals / (Topics logged per interval * Intervals recorded per day)

= 171072 / (3 * 144)

= 396 days

The logging capacity is dynamically calculated and displayed on the “Topic

Selection Page” (see Table 3– 4 for samples).

*Topics are selected by default.

NOTE: Weighted Inputs are inputs that have been assigned a weighted value. The default weight in the Twido program is 1.

Setting Up a Device Log Export

You can configure the EGX300 to export data logs as complete logs or as incremental exports. Incremental exports are recommended as they greatly reduce the amount of data exported. An incremental export contains only the intervals logged since the last successful export.

The Device Log Export option allows you to export device logs in three ways: by E-

Mail, FTP, or HTTP. Refer to your supervisory system’s user guide for the method appropriate for your application.

Configuring a Device Log Export for EVO Compatibility

At this time the EVO importer can only process data logs exported in English. If using EVO in this solution, set data logs to always export in English. This will ensure EVO will receive data logs in the language its importer currently supports.

1. In the address bar, type the IP address of the EGX300 followed by

/evo_compatibility.shtml (Figure 3-10). Press Enter.

2. Enter a whole number of 1 or greater in the Historical Intervals field.

NOTE: You must send at least one historical interval in order to calculate the difference between the current export’s first value and the last value collected.

3. Select the check box for Always Export in English.

4. Click Apply, then Main Interface to return to the EGX300 home page.

You can view, monitor, and reset pulse counts from the EGX300 web interface.

Viewing Pulse Counter Topics on the Real Time Data Page

The Monitoring tab provides real-time data for single configured devices. You can view the topics and raw counter values for each supported input on the Basic

Readings page. Summary device and real time trending pages are not available for

Twido WAGES devices types. To view the Basic Readings Page:

1. Click the Monitoring tab.

2. Click Real Time Data > Single Device Pages, and select your Twido WAGES

device. Device data displays, as illustrated in Figure 3-11.

3. Verify that valid data is being displayed. If a device is not being read, it will read

Out of Service.

Monitoring the Pulse Counter for Roll-over

The maximum pulse count before a counter resets to ‘0’ is 999,999,999,999. You can manually monitor this value on the EGX300 Basic Readings page for each device, described above.

We recommend that you use a PC-based supervisory system, such as SPM, or

REM services, such as EVO, to monitor this value for roll-over detection. See your supervisory system user guide or online help for more information on setting up alarms for roll-over detection

Resetting a Pulse Counter

You can reset pulse counters from the EGX300 Twido setup page (Figure 3-12).

Administrator rights are required to access this page.

To reset a counter:

1. Open a web browser.

2. In the address bar, type the IP address of the EGX300 followed by

/twido_wages_setup.shtml. Press Enter.

3. Select the Twido WAGES device from the Device drop-down menu.

4. Check the boxes for the inputs you want to reset. Click Reset Counters.

NOTE: Weight values on this page should be set to ‘1’ by default, as determined by the Twido WAGES program installed on the PLC. Do not set the weight to any other value from this page. Doing so may produce inaccurate data. This solution requires that you adjust weights from the supervisory system.

Supported Modbus Register Reads

The data for each channel is organized in 20 register blocks. The EGX300 needs only 3 registers per channel for real time data display and a maximum of 7 for logging. Since the Twido does not support scattered register reads, you should keep the number of reads as small as possible, even if it means reading many unused registers.

Appendix B—Twido Program Structure


Twido Program Structure

The PLC program is divided into three segments: System Overhead, Channel

Update, and Accumulation Sub-Routine.

System Overhead

The System Overhead section of logic is not specific to a particular channel and acts as a placeholder for future modifications. There is a rung of logic for the master reset, which will reset all of the accumulators and raw count values to zero. The bit that controls this is %M0 and can be set “true” by your supervisory system. After the reset is complete, the program will reset the bit at the end of the program scan.



Twido Program Structure

Channel Update

63220-095-04A1

12/2012

This section calls the Accumulation Sub-Routine for any channel that senses the positive transition from its associated field device.

In the Channel Update section, there are only two rungs of logic for each channel.

These two rungs of logic are identical for all channels except for addressing.

First Rung

The first rung monitors the status of the input point for the channel. A positive transition of the input point will set a pointer to a value equal to the channel number.

The first channel is designated as channel zero. With the channel number set, program execution is directed to the accumulation sub-routine. When the execution of the sub-routine is complete, program execution returns to the rung immediately following the rung that called the sub-routine.

Second Rung

The second rung will reset the raw pulse count and accumulators associated with the channel. Two things can cause the accumulator to reset: the Master Reset

(%M0) mentioned above and a channel-specific reset contained in the channelspecific command word. The channel-specific command word is set by the supervisory system. After the reset occurs, the logic will automatically return the reset bit to a false condition.

The data is mapped in such a way to capitalize on the Twido feature that allows operations on structured objects. Using the syntax of %MWxxxx:L, where L is the number of consecutive objects starting at address %MWxxxx, all eight of the registers for the accumulated values can be reset in one operation.

Accumulation Sub-Routine

This section contains the controlling algorithm for developing a user-defined representation of the accumulated pulses. The logic is contained once in the program but may be called multiple times in one scan by the Channel Update section. The “calling” sequence is mentioned above.
