The 3170-MBS Modbus Slave Communication Adapter can interface up to 8
Rockwell Automation FLEX and/or Integra I/O modules directly with any Modbus
Master. The following functionality is available:
Multi-drop on an RS-485 link with other Modbus compatible devices
Interface Analog and/or Discrete I/O directly to a Host
Add FLEX I/O into applications where other manufacturer’s devices are
already in use
The 3170-MBS module is simple to use, requiring only the setting of several dip-
switch options. The Flex and Integra module data images are pre-mapped into
Modbus addresses to simplify reading and writing using standard Modbus
commands.
The 3170-MBS has read/write access to all Flex and Integra modules. This
allows a Host system to perform all functions necessary to get all I/O modules
functioning. All register data values can be accessed using Function Codes 3, 4,
6 and 16. Bit level Function Codes 1, 2, and 5 are also supported.
