The ProSoft 3170-MBS Modbus Slave Communication Adapter is designed to interface up to 8 Rockwell Automation FLEX and/or Integra I/O modules with any Modbus Master. It offers a seamless solution for integrating FLEX I/O into applications that use devices from other manufacturers.

Key Features

• Multi-drop Communication: Supports RS-485 link for multi-drop configurations with other Modbus-compatible devices.
• I/O Interface: Directly interface Analog and Discrete I/O to a Host system.
• Flexibility: Add FLEX I/O to applications with existing devices from other manufacturers.
• Ease of Use: Simple dip-switch configuration options.
• Pre-mapped Data Images: Pre-mapped Flex and Integra data simplify Modbus read/write operations using standard commands.
• Full Functionality: Supports read/write access to all FLEX and Integra modules, supporting Function Codes 1, 2, 3, 4, 5, 6, and 16.
