The unit converts between \u003cstrong\u003eModbus TCP and PROFIBUS DP\u003c\/strong\u003e, acting as a PROFIBUS DP slave while supporting both client and server roles on Modbus TCP. For integrators migrating devices or linking a PROFIBUS DP master to a Modbus TCP network, the GT200-DP-MT delivers predictable protocol handling, solid galvanic isolation on the PROFIBUS interface, and a compact feature set designed for control-room and panel installations.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePROFIBUS DP slave:\u003c\/strong\u003e Automatically detects baud rates from 9600 bit\/s to 12 Mbit\/s so it integrates with a wide range of PROFIBUS masters without manual link configuration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModbus TCP roles:\u003c\/strong\u003e Can operate as both Modbus TCP client and server, offering flexibility for different network topologies and master-slave assignments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-server\/client support:\u003c\/strong\u003e As a Modbus TCP client it can communicate with up to 36 Modbus TCP servers, simplifying polling of multiple devices with distinct IPs or identifiers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConcurrent connections:\u003c\/strong\u003e As a Modbus TCP server it accepts up to 36 client connections and supports the common function codes 03H, 04H, 06H and 10H for read\/write operations.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eData capacity:\u003c\/strong\u003e Supports up to 244 bytes of input and 244 bytes of output on both PROFIBUS and Modbus sides, sufficient for moderate I\/O maps and tag sets.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRugged isolation and range:\u003c\/strong\u003e Provides 1 kV galvanic isolation on the PROFIBUS interface and an extended operating temperature range down to -40C and up to 70C for industrial environments.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThe GT200-DP-MT is best for control engineers, system integrators, and industrial automation technicians who must connect legacy PROFIBUS DP systems to modern Ethernet-based Modbus TCP networks.
