Description
Overview
The Modbus TCP coupler BL200 adopts a web configuration and supports simultaneous access by 5 Modbus TCP clients. It is compatible with function codes 01/02/03/04/05/06/15/16 and supports a maximum sum of 8192 bytes for process data input and output. It can expand up to 32 M-series IO modules with different functions such as DI, DO, AI, AO, thermocouples, and thermal resistors. Adopting a high-speed backplane bus, with 32 slave stations fully loaded and a maximum scanning cycle of 10ms. The coupler comes with diagnostic function, which can monitor the communication status of the IO module in real time and provide a 2000mA drive circuit for the IO module.
Modbus TCP coupler BL200 can be adapted to Schneider, Siemens, Keyence Codesys, PLCOPEN, Huichuan, Delta and other Modbus TCP master stations are compact in structure and small in size, suitable for various industrial automation systems.
Functional Features
