2. Key Features
The FCM100EE realizes high-efficiency protocol conversion between 100 Mbps Ethernet and 2 Mbps/268 Kbps fieldbus, establishing a stable communication link between the ZCP270 controller and FBM modules. It supports dual-module hot swap with automatic failover, ensuring zero downtime even when a single module fails, which is critical for high-reliability industrial control scenarios. Equipped with a multi-mode fiber port (62.5/125 µm), it can extend the communication distance up to 1,830 m (6,000 ft) for 268 Kbps fieldbus signals, facilitating remote FBM deployment. The module is hot-swappable, allowing replacement without shutting down the entire system, significantly reducing maintenance downtime. It is equipped with LED status indicators for real-time monitoring of module operation, and its working status can be further monitored and managed through I/A Series system management tools. The FCM100EE has obtained multiple certifications including CE, RoHS, UL/UL-C, ATEX (Zone 2), and Marine (BV), ensuring compliance with international industrial standards and adaptability to various application environments.
3. Installation & Wiring
The FCM100EE can be installed on a DIN rail or a 200-series baseplate, supporting both horizontal and vertical installation modes for flexible deployment in control cabinets. It is compatible with P0926KE (2-position), P0926HM (4-position), and P0926JM (8-position) baseplates, allowing flexible configuration according to system scale. The fiber port is used to connect to the MESH network (100 Mbps) via multi-mode fiber, ensuring high-speed and stable long-distance communication. The fieldbus port is connected to FBM modules through a terminal block, supporting both 2 Mbps and 268 Kbps signal transmission. The module is equipped with redundant 24 VDC input terminals, allowing connection to primary and secondary power supplies to prevent power failure. For redundant configuration, two FCM100EE modules can be installed in adjacent baseplate slots, forming a fault-tolerant pair to further improve system reliability.
4. Application
The FCM100EE is widely used in I/A Series DCS systems in industries such as power, chemical, oil and gas, and pharmaceuticals, providing core communication support for distributed control. It is particularly suitable for remote I/O scenarios, connecting remote 100-series or 200-series FBM modules to the central ZCP270 controller, realizing on-site data collection and control command issuance. As a high-speed communication link, its 100 Mbps Ethernet port enables seamless integration of the I/A Series system with the plant-level network, facilitating centralized management and data sharing. With its Class G3 harsh environment rating, it can operate stably in high-dust, high-humidity, and strong electromagnetic interference industrial sites, ensuring the continuity and reliability of industrial control processes.
