GF0-57CQD-002
Schneider Electric GF0-57CQD-002 Communication Interface Module (Modicon M340 PLC Expansion Unit)
Product Description
The GF0-57CQD-002 is a specialized communication interface module designed for Schneider Electric’s Modicon M340 programmable logic controllers (PLCs), serving as a bridge between the PLC and industrial networks. Its primary function is to enable secure and high-speed data exchange between the M340 controller and external devices such as HMIs, SCADA systems, and other PLCs, facilitating centralized monitoring and control in manufacturing, water treatment, and building automation applications. For instance, in a food processing plant, it can transmit real-time production data (e.g., packaging line speed, batch counts) from the M340 to a SCADA system, allowing managers to optimize throughput while ensuring compliance with hygiene standards.
Featuring dual Ethernet ports (10/100Mbps), the module supports multiple industrial protocols, including Modbus TCP/IP, Ethernet/IP, and DNP3.0, ensuring compatibility with both Schneider and third-party systems. This versatility allows it to integrate seamlessly into mixed-vendor environments—for example, connecting a Modicon M340 PLC to a Rockwell Automation PanelView HMI via Ethernet/IP, while simultaneously communicating with a Siemens SCADA system using Modbus TCP/IP.
