This module plugs directly into the drive's option slot, creating a seamless Ethernet connection for SCADA systems, HMIs, or any Modbus TCP master. It effectively translates drive parameters and commands into the universal Modbus register map. Therefore, it simplifies integration into plants where Modbus TCP is the standard for device-level communication.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eKey Benefits: Dual-Port Simplicity and Deep Drive Access\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cspan\u003eA standout feature is its two independent RJ45 Ethernet ports, which offer superior network flexibility. You can use one port for the main control network and the second for a PC running Drive Composer Pro, eliminating the need for a network switch at the drive. Moreover, the adapter provides comprehensive access for reading real-time data (current, speed, power) and writing control commands (start, stop, speed reference). In addition, its wide operating temperature range ensures reliable performance in harsh electrical rooms or outdoor enclosures. Consequently, you get a versatile and rugged solution for monitoring and controlling drives over Ethernet.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eTechnical Data \u0026amp; Specifications\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cspan\u003eHere are the definitive technical parameters for the FMBT-21 adapter:\u003c\/span\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eManufacturer \u0026amp; Model:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e ABB FMBT-21\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eModule Type:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Modbus TCP\/IP Communication Adapter\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003ePrimary Protocol:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Modbus TCP (Client\/Server)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eNetwork Interface:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Dual 10\/100BASE-TX RJ45 ports, auto-negotiating\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003ePower Supply:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e 24V DC (typically sourced from the drive)\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eOperating Temperature:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e -20°C to +60°C\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eStorage Temperature:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e -40°C to +85°C\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eKey Functions:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Drive control, parameter access, fault reset, real-time monitoring\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eSoftware Tools:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Compatible with ABB Drive Composer Professional\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eDimensions (H x W x D):\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e 60 x 300 x 160 mm\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eWeight:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e 1.02 kg\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eOrigin:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Sweden\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eCondition:\u003c\/span\u003e\u003c\/strong\u003e\u003cspan\u003e Brand New, Active Product\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cstrong\u003e\u003cspan\u003eTypical Applications \u0026amp; System Integration\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp class=\"ds-markdown-paragraph\"\u003e\u003cspan\u003eThis adapter is perfect for integrating ABB drives into larger Modbus TCP SCADA networks, common in water\/wastewater, building automation, and renewable energy systems.
