Allen-Bradley 3170-MBS Modbus Slave Network Interface Adapter

Description

The Allen-Bradley 3170-MBS Modbus Slave Network Interface Adapter is an industrial communication device designed for integration into automated control systems, supporting the Modbus communication protocol as a slave device. As a slave device, it operates in a passive communication mode, waiting for requests from Modbus master devices (such as PLCs, HMIs, or upper-level controllers), then executing read/write commands and returning corresponding response data. It enables seamless connectivity between terminal industrial devices like sensors, actuators, or small controllers and larger Modbus-based industrial networks, facilitating data exchange across multi-device systems. While specific hardware specifications are not available, as part of Allen-Bradley’s industrial automation product line, it is engineered for rugged industrial environments, likely featuring rail mounting for easy installation in control cabinets, and may include electrical isolation to resist interference from industrial electrical noise. It supports interoperability with Modbus TCP, ASCII, and RTU protocol variants, enabling integration of mixed master-slave networks, and supports read/write operations for multiple data types including boolean values, integers, floating-point numbers, and strings to meet diverse industrial data transmission needs.
