FCM100ET field communication module

The FCM100ET is a field communication module developed for industrial automation systems, typically used to enable data exchange between distributed control systems (DCS) or programmable logic controllers (PLCs) and various field devices. It is widely applied in process industries such as petrochemicals, power, and water treatment due to its stable communication performance and strong compatibility. Below is its detailed information:

1. Core Functions

Multi-Protocol Communication Conversion: Supports mainstream industrial communication protocols, including Modbus RTU/TCP, Profibus-DP, and Ethernet/IP. It can convert data formats between different protocols to connect field devices (e.g., transmitters, valves, sensors) with upper-level control systems.
Real-Time Data Transmission: Ensures high-speed and low-latency data exchange (typical communication latency ≤10ms) to meet the real-time monitoring and control needs of industrial processes.
Redundant Communication Support: Equipped with dual Ethernet ports or dual serial ports for redundant configuration. If one communication link fails, the other automatically takes over to avoid data transmission interruptions and improve system reliability.
Device Management & Diagnostics: Provides online device status monitoring (e.g., connection status, signal strength) and fault self-diagnosis (e.g., communication timeout, protocol mismatch). Fault information is sent to the upper system via alarm signals for quick troubleshooting.
