Each wellhead was equipped with various sensors and meters that needed to be monitored and controlled from a central HMI, often miles away from the assets in the field. Redundant solar and wind generators were installed at each wellhead to support the electrical needs of the pumpstations, temperature meters, cameras, and cellular modules. In addition to asset management and remote control capabilities, data logging for remote surveillance and alarm notifications was a key demand from the customer. Terra Ferma’s solution needed to be power efficient, reliable, and capable of supporting high-bandwidth data-feeds. They needed a multi-link cellular connection to a central server that sustained reliable and redundant monitoring and control of flow meters, temperature sensors, power supply, and event-logging; including video and image files. This open-standard network needed to interface with the existing SCADA and proprietary network management software.

Moxa was asked to provide a connectivity solution for one of the world's leading cosmetics companies. This multinational corporation, with retail presence in 130 countries, 23 global braches, and over 66,000 employees, sought to improve the efficiency of their production process by migrating from manual monitoring to an automatic productivity monitoring system. The production line was being monitored by ABB Real-TPI, a factory information system that offers data collection and analysis to improve plant efficiency. Due to software limitations, the customer needed an OPC server and a corresponding I/O solution to collect data from additional sensor devices for the Real-TPI system. The goal is to enable the factory information system to more thoroughly collect data from every corner of the production line. This will improve its ability to measure Overall Equipment Effectiveness (OEE) and translate into increased production efficiencies. System Requirements • Instant status updates while still consuming minimal bandwidth to relieve strain on limited factory networks • Interoperable with ABB Real-TPI • Small form factor appropriate for deployment where space is scarce • Remote software management and configuration to simplify operations

One of Singapore's leading engineering and system integration providers needed exactly the right solution for a challenging gas pipeline application. With experience in assembling systems for many different vertical markets such as oil and gas networks, factory automation, and building automation, this system integrator realized that monitoring the temperature of a gas pipeline tunnel is crucial for safe operations. In the confined space of a tunnel, temperature rises easily, and the overheating could cause pipeline fractures that could lead to gas leaks or even explosions. Meanwhile, the long and narrow dimensions inherent to a tunnel meant that more home run cables must be installed to link all the temperature gauge data acquisition I/O devices back to the pipeline's SCADA system, increasing cabling costs. With these stakes and in these conditions, the simple act of regularly taking the temperature transforms into a formidable yet absolutely necessary requirement. System Requirements • Real-time tunnel temperature monitoring to provide early excessive heat warnings • Data acquisition and system management with SCADA system • Ethernet data acquisition system, but with efficient, cost-effective wiring

One of the largest steel factories in China needed proper communication control units for data processing and protocol conversion with the devices at remote field sites. These computers would replace the IPCs and can easily create a distributed system at the front-end site with a centralized management platform at the back-end control center. This stainless steel factory has deployed a power substation system that contains several subsystems. Each subsystem uses smart meters, and needs to optimize resources, centralize management, and enhance efficiency. In addition, all distributed smart meters at the field site need to be centrally monitored and managed by a system called the “CCMS3000 central management system”, located at the control center. Each 35KV/10KV substation communicates with the back-end server via Intranet, and manages the centralized management and monitoring of the 35KV/10KV. The entire system aims to optimize the power network management and maintenance cost, enhance power distribution quality and management, and deliver real-time discovery, analysis, recording, and handling of problems. The CCMS300 central management system is expected to bring reliability to real-time monitoring of the operation status of all devices at the substations. It needs to perform several tasks, such as analyzing historical workload, power consumption, and system balance, as well as enhance system or device operation efficiency.

Gas tankers are massive ships with a limited crew, making them extremely difficult to monitor. Video surveillance systems, which use a large number of widely distributed devices, and fire prevention systems are both crucial elements of a gas tanker monitoring system.The system used for this application is a legacy analog CCTV surveillance system that is completely independent from the main monitor and control SCADA system. With this system, the administrator responds to an event by first using the SCADA system to locate the event, and then accesses the appropriate surveillance camera from the CCTV system to view the location. The goal is to upgrade the system so that only one step is required. This is done by integrating the CCTV surveillance system into the SCADA system, in which case the surveillance system becomes a SCADA sub-system, making centralized control and monitoring possible.System Requirements- Upgrade to an IP video surveillance system for integration with the existing SCADA system- Live video display (through the SCADA system)- Enable events in the SCADA system to automatically trigger live video display- All the devices need to be of rugged design and have an anti-explosion defense
