- Wastewater Treatment Facility Controls Upgrade - Seattle, WA -

New Interface

Modernized aging control system by replacing main control panel and existing telemetry network and adding a centralized SCADA computer which allows monitoring and control of each device and subsystem for this wastewater treatment system. New features include the following:

  • New SCADA system with secure remote web based monitoring and control
  • Systemwide datalogging and reporting
  • Analog trending for each analog device
  • Enhanced alarm management and notification system to reach offsite operations team
  • New high speed wireless network
  • New high resolution video monitoring and recording integrated into operator interface and SCADA system
  • Allows for control and monitoring of every device in the system
  • Reporting system designed to track 6 years of data

- Alvey palletizer control and network upgrades -

Network Upgrade

Modernized PLC processor and upgraded troublesome DeviceNet network to a modern high speed EtherNet/IP network in this Alvey 940 series palletizer. During this process all existing variable frequency drives were also upgraded to AB 523 series drives. Additionally all remote IO interfaces and cabling were upgraded to be compatible on new EtherNet based network. What we did not affect was the existing IO. This saved implementation time by removing the need to re-test all existing/untouched IO device wiring. As a result of the upgrade, the plant is able to securely connect the plant network to the palletizer machine network allowing easier maintenance and remote access to the machine as well as to monitor production. This upgrade has improved machine reliability and reduced downtime.

UniSea

- Cod Line - Dutch Harbor -

UniSea Cod Line

Provide programming and commissioning services to automate the conveyance of cod to various specialty process machinery throughout the facility. This project consisted of 96 drives and 12 PLCs with associated HMIs to allow operators to easily operate each product line.

Washington State Department of Transportation

- I90 Tunnels SCADA upgrade -

I90ScadaScreens

Programmed complete SCADA system including over 45 PLCs in this large upgrade project. Developed SCADA architecture based on VMware infrastructure aand developed interface for operations and maintenance teams to monitor and control fire and life safety systems, ventilation lighting,and electrical controls.

This project required integration with Fire detection an suppression, telephony, video monitoring, and electrcal systems. Many aspects of this control system and network architecture include many redundancies to ensure high availability and made vast improvements over previous control system.

- Ongoing Support -

Control  Panel 1

Long time controls support for multiple projects including Dissolved Oxygen upgrade which automated the DO process by modulating new Variable Frequency Drives to maintain consistancy. Other projects include HMI replacement, regular effluent flowmeter calibration, and other projects as needed.

Washington State Department of Agriculture

- PLC Integrity Verification -

WSDA Port

Routinely verify PLC code integrity to ensure that no tampering has occured and only authorized modifications have been made to verified PLC logic.

Cylance

- ICS Security Training System -

Designed and built a mobile training system that consisted of a Human Machine Interface (HMI) on a dedicated virtual machine which communicated to a PLC over Modbus to control a stepper motor. This system was used as a training tool to demonstrate security vulnerabilities in a SCADA system.
