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 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.
