cable requirements. RS485 and Ethernet are examples of communication-network standards.

Communication protocol: A language or convention used for reliable transmission and reception of binary data. A communication protocol is often independent of the physical method or network used for transmission. Modbus RTU and TCP/IP are examples of communication protocol standards.

DDE Server: A software application that typically runs in the background, gathering information from the network and providing the information in DDE format for use by one or more applications. The PMCS DDE Server is included in the PMCS Network & Device Configurator and comes in versions optimized for Ethernet TCP/IP or RS485 Modbus RTU networks.

DDE: Dynamic Data Exchange. A Microsoft Windows standard for efficient sharing of data between applications on the same PC. See also NetDDE.

Ethernet Gateway: A POWER LEADER device used to connect four RS485 Modbus RTU networks to an Ethernet TCP/IP network. The Gateway increases performance of a PMCS system through multiple Modbus networks and reduces overall wiring costs through reuse of existing Ethernet LAN wiring.

Ethernet: An industry-standard communication network commonly used for local- area networks (LANs) of PCs. Ethernet PMCS systems provide very high-speed, reliable communications at 10 megabits per second.

Event Logger: A standard PMCS application that efficiently analyzes, sorts, and logs unusual system behavior such as circuit breaker trips, undervoltages, and overcurrents. Extensive data-logging capabilities make it a useful tool for analyzing and predicting system maintenance patterns.

Host PC: The PC running the PMCS DDE Server is referred to as the Host PC. All other PCs running PMCS client programs are referred to as Viewer Workstations or networked PCs.

Interface Toolkit: An optional PMCS tool used to quickly generate accurate and friendly graphical user interfaces. The Interface Toolkit provides dozens of wizards to efficiently create intelligent one-line diagrams, equipment elevation views, floor plans, 3D virtual-faceplate views, and tabular displays.

Modbus Concentrator: A POWER LEADER device used to connect eight commnet networks to an RS485 Modbus RTU network. The Concentrator provides full compatibility between the PMCS software and the extensive line of POWER LEADER devices with commnet communications, as well as simple expansion of a RS485 Modbus RTU network to up to 247 devices.

Modbus RTU: An industry-standard, nonproprietary communications protocol typically used in medium-speed networks (up to 38.4 kpbs) on RS485.

NetBEUI: A network protocol usually used in small, department-size local-area networks of 1 to 200 clients.

NetDDE: A version of Dynamic Data Exchange (DDE) that allows communications between applications running on different PCs over network connections.

NT Service: A designated piece of software which runs in the background of Windows NT and can be set to automatically start when the machine is booted up. For example, the PMCS DDE Server can be set to operate as a Windows NT Service, rather than a manually-launched application. Another advantage of NT Services is that they are persistent across multiple user logins and logouts; that is, PMCS DDE
