Metro Gas Real Time Measurement Solution

Presented by

RockPoint Automation Inc. and Comgas-Consultores

Bringing Automated Measurement Systems to the World

The following presentation is a high level outline of the Metrogas project executables, technical data and proposed system architectural layout.

Installing Controlwave Micro RTU’s at each distribution station.

The proposed RTU's have an optional 10/100 Mb Ethernet I/P port and have the ability to

Calculate flow rates, hourly and daily volumes and it can easily handle all other associate

computation tasks required to provide RTM measurement data transfer. Control Wave Designer

programming software supports all five IEC 61131-3 programming languages and is enhanced

with a powerful library of ACCOL III process control function blocks allowing the use of a single

controller for logic, process control functions, measurement, calculations and data storage.

Engineers can also develop their own reusable function blocks, further reducing engineering time

and cost. These capabilities are further enhanced with time stamped alarming and historical

archive storage within the PLC/RTU itself to provide maximum data integrity.

The following presentation flow diagrams demonstrate the architectural proposed layout

and System functionality.

The Control Wave Micro offers exceptional flexible communication capability with up to

Eleven Programmable serial ports.

Optional built-in spread spectrum radios and worldwide dial-line modems offer

convenient integration and communication choice flexibility.

The solution presented for communication would be to use CDMA cellular wireless

service in the area if it is available and a TCP/IP connection instead of a typical serial

connection to utilize maximum data transfer speeds.

Collected Station Information Data Transfer Archiving

The data collected by the Harvester Utility is stored in files at the PC workstation. These

files can be converted to a variety of formats using the Open BSI Data File Conversion

Utility, making them accessible to other programs. This information can then be utilized

throughout the organization in the required program format required for the areas of

operation. Comma Separated Variable format (CSV) - for use in Microsoft® Excel ODBC - for use in Microsoft® Access Open Enterprise database Coastal Flow Measurement's Flow-Cal™ package

System Protocol and Data Collection

The protocol from Field to Office will be Bristol BSAP. This enables easy data transfer of

Lists, Arrays, Archives and Audit trails that can be archived, printed and used by both daily

pipeline operations for system surveillance and nomination purposes and data accounting

personnel for custody transfer billing.

Operations field technicians will also be able to use the same software (Netview and

Dataview) to communicate locally to the RTU’s for on-site troubleshooting and archiving of

station volumes alarms etc.

Data Retrieval Field device to Control Center or Office

The data would be polled from a central location using Bristol’s Data Harvester Utility

located on a designated desktop computer.

The data would then be Converted to SAP usable data by using Bristol’s Conversion Utility.

This utility can be used to format data into CSV (Excel) or ODBC (Access). This utility would

also be installed on the designated desktop computer.

Extra Ports in Control wave for “REMOTE ACCESS” could also be programmed to allow

remote access for trouble shooting if the communication system will allow for it.

Data Collection

Data can be collected at scheduled intervals (e.g. hourly) or at a specified set of up to ten times during the day, or based on a pre-defined collection scheme which takes into account various factors affecting communications such as time scan length. The ten specified times are an exception to the RTM hourly data register poll using Data Harvester

Software Requirements and Deliverables

The Following Software will be required for the system to be fully integrated and have

the capability to be polled or scanned station by station at a pre-configured time

schedule. This software will also be required to change the data information stream transfer programmable language into a SAP friendly program to reduce the need for manual data entry that will reduce the human risk data entry error.

This standard industry software will be customized to fit the current Metrogas system requirements as well as allow for future upgrades and developments.

Software Utilities Definitions

OpenBSI Utility Packages

Three basic OpenBSI Utilities packages are available to offer the

optimum functionality to technicians, engineers and operators:

BSI Config - Designed for technician set-up and configuration of all Bristol

RTU,PLC, Flow Computer, controller and 3808 transmitter products. It provides

local connection to the device to be configured and supports:

Localview/Netview for local connection to Bristol products

Set-up and configuration of ControlWave, 33XX, 3530 TeleProducts and 3808 MVT

transmitters

TeleProducts web pages & ActiveX controls

Firmware flash-download of all flash-based products

Hardware diagnostics

Supports BSAP and IP networks

OpenBSI Local Edition - Designed for technicians and engineers. Includes all of

the set-up features of BSI Config and provides additional functionality for a higher

level interface. Additional utilities include:

DataViewer for access to real-time and historical access

Communication Statistics

ACCOL and ControlWave Designer file downloaders

TeleProduct web pages

ActiveX Controls for custom web pages

OpenBSI Network Edition - Designed for engineers and operators. Includes all

Of the capabilities of the Local Edition but allows global, network-wide access to

all products. Additional utilities include:

NetView for global, network-wide access to real-time & historical data, programming and

operator HMI

Network tuning wizard

Project Summary, Roles and Responsibilities• The proposed Metrogas measurement system upgrade, is a system that all components have

been used and proven in the context that they have been presented during this presentation.

• The time frame required for full completion of this proposed upgrade including the following action items.

• Procurement of all equipment not including any electrical or civil works that must be done at the stations or Control Center to allow for the installation of new equipment.

• Installation, commissioning ( We propose FAT and SAT testing would be completed at the same time onsite to reduce man hours required to perform the same testing sequences and would include vendor personnel)

• Working with the Client Representatives a complete roles and responsibility flow chart will be constructed including a complete scope of work document before the actual work commences. This would include all company related HS&E and O&M policies and procedures to ensure a safe and productive work environment.

• Working with the Client Representatives a priority list of stations would be generated and used as the working guide.

• Working with the Client Representatives a training program will be centered around Metrogas technical personnel onsite assisting with installation, programming commissioning and testing. (This will be a intergraded hands on training program)

• A completed Client approved training program will be completed after the system is online and fully operational. The extended Training program will be considered part of the project scope and be included in the actual project costs and be delivered by qualified personnel.
