1978 Case Study: Natural Gas Fueling Stations Communications
In recent years, environmental benefits, improvements in automotive engine design, and the lower production cost of natural gas (compared to heavy diesel fuel) have made use of natural gas vehicles (NGVs) more attractive and cost feasible—particularly for public transportation. One of the other advantages of NGVs is that they can be refueled simply by tapping into existing natural gas lines. The Madrid city government has invested $47 million dollars in a custom refueling station and parking depot for 300 natural gas powered buses in the Sanchinarro area of Madrid. An Ethernet-based industrial automation, data acquisition, and communications system—based on Opto 22’s SNAP PAC platform and implemented by Spanish integrator Optomation Systems—serves as the communications backbone that keeps the Sanchinarro station operating efficiently. The system employs a number of industrial and IT protocols, including FTP, SNMP, OPC, Modbus/TCP, and M-Bus to communicate more than 600 different data values to and from the Sanchinarro station’s equipment, systems, and external databases.

1943 Case Study: Unmanned Ocean Vehicles
Unmanned ocean vehicles are sometimes referred to as the “satellites of the sea,” because they’re incredibly durable, operate largely autonomously, navigate long distances, and are used for remote research, exploration, detection, and data collection. The vehicles designed and built by Payne Kilbourn and his company, Unmanned Ocean Vehicles Inc., are energy scavenging vessels that rely on a combination of wind, photovoltaic (solar), and motion power. As Kilbourn developed his 20-foot prototype, he looked at a number of PLC-based solutions before settling on Opto 22’s SNAP PAC input/output modules and programmable automation controllers. The SNAP PAC System is able to handle the large quantity and variety of inputs and outputs needed for power and navigation, as well as sensing, monitoring, and gathering data. In doing so, the SNAP PAC serves as a central controller that connects to and regulates a multi-vendor team of micro controllers and marine instrumentation, each with its own area of responsibility, including wing (sail) control, steering, and power management.

1935 Case Study: Mariah Meat Packing Plant
At the Mariah Meat Packing Plant, rising utility costs were reducing profits and threatening the plant's very existence. Holmes Energy, experts in facility energy management, designed and installed an AutoPilot Energy Information System to monitor and reduce Mariah’s electrical costs. The AutoPilot system, based on hardware from Opto 22, provided connections to electric meters and facility machinery and equipment. Data gathered by the AutoPilot hardware showed that Mariah’s refrigeration system accounted for two thirds of the plant’s total electrical consumption and also revealed longstanding problems with the system that were costing Mariah hundreds of thousands of dollars. Ultimately, the information provided by the AutoPilot system helped Mariah reduce its utility costs and increase profits by providing a way to make critical business decisions regarding plant operations based on real-time data, rather than estimates or educated guesses.

1921 Case Study: Mogale Gold
South African miner Mintails Limited has implemented Opto 22-based control systems that manage a series of processes needed to extract gold from mine tailings. These processes involve pumping water to the tailing dump, and monitoring and control of differential pressure sensors, flowmeters, and other instrumentation. Also, during the carbon in leach and elution phases, gold is dissolved, absorbed onto carbon and then stripped off by a chemical mix of caustic and cyanide. For these processes, the control system opens valves; starts and stops feed pumps; fires up diesel burners and heat exchangers to heat the solution; executes PID control to maintain proper flow rates; and monitors the pH level of the cyanide so it doesn't convert to poisonous cyanide gas.

1812 Case Study: Automated Interface Solutions

Systems integrator Automated Interface Solutions (AIS) used the SNAP PAC System to solve a problem for one of its large customers, a manufacturer of polypropylene film.

Part of the company’s manufacturing process used older Measurex and Foxboro systems, tied by custom software to an Allen-Bradley® ControlLogix® PLC. Parts were becoming difficult to get and the custom software was expensive to change.

AIS installed the SNAP PAC System to replace the older hardware. Opto 22 PACs communicate natively with Allen-Bradley PLCs using the EtherNet/IP protocol. AIS worked with its customer to define all of the process control data it wanted the A-B system to have access to, and then made that data available within the shared memory of the Opto 22 PACs.

In addition, the SNAP PAC System sends data via OPC to the company’s Wonderware® Intouch® HMI, which displays real-time information on scanners, indicates die bolt positions (on or off), roll lengths and averages, and other statistics. Data transfer is accomplished via OPC, and more than 6,400 I/O tags are passed through to the HMI without issue.

1793C Case Study: Hong Kong Power Plant (Chinese)

This document is written in Chinese.

The Lamma Power Station in Hong Kong is using Opto 22 SNAP PAC standalone controllers to control heat, pressurization and other critical processes. The Opto 22 PACs connect to weigh scales, conveyors, pressure transducers, and thermocouples to ensure that the coal burning operations taking place at Lamma are executed safely and optimally.

For example, analog I/O modules wired to scales measure the weight of the coal prior to its delivery to the furnaces and sends these figures to the controller. Based on these readings—and whether they're low or high—the controller then instructs the conveyors delivering the coal to the furnaces to speed up or slow down appropriately, so the furnaces generate the proper amount of heat needed to spin turbines that produce the power.

At the same time, integrated circuit temperature derivative probes (ICTDs) connected to thermocouple analog input modules monitor the actual furnace temperatures, which are then used in PID calculations to regulate the temperature via analog output modules.

1740 Case Study: NASA - JPL
NASA’s Deep Space Network site in Madrid experienced a crisis when engineers detected cracks in the elevation bearings of a 230-foot parabolic antenna that enables 24/7 monitoring of satellites, space probes, and spacecrafts. These bearings support the 4 million pound weight of the antenna as it tilts up and down. To determine the precise nature of the problem, the antenna's bearings will be lifted and the existing shim pack removed and replaced with load cell transducers, which will convert the measured pressured into an electrical signal output and deliver it to an Opto 22 SNAP PAC System. Specifically, SNAP-AIMA analog input modules will connect four sets of load cells (one for each set of bearings) to SNAP-PAC-EB2 brains, which will receive accurate load cell readings as the antenna moves across the bearings. NASA’s Jet Propulsion Laboratory will then be studying the data, formulating theories, and determining why the antenna’s bearings have been cracking.

1793 Case Study: Hong Kong Power Plant

The Lamma Power Station in Hong Kong is using Opto 22 SNAP PAC standalone controllers to control heat, pressurization and other critical processes. The Opto 22 PACs connect to weigh scales, conveyors, pressure transducers, and thermocouples to ensure that the coal burning operations taking place at Lamma are executed safely and optimally.

For example, analog I/O modules wired to scales measure the weight of the coal prior to its delivery to the furnaces and sends these figures to the controller. Based on these readings—and whether they're low or high—the controller then instructs the conveyors delivering the coal to the furnaces to speed up or slow down appropriately, so the furnaces generate the proper amount of heat needed to spin turbines that produce the power.

At the same time, integrated circuit temperature derivative probes (ICTDs) connected to thermocouple analog input modules monitor the actual furnace temperatures, which are then used in PID calculations to regulate the temperature via analog output modules.
