Modbus Slave Network Interface Adapter for FLEX I/O

Modbus Slave Network Interface Adapter for FLEX I/O


Discontinued: No new product for sale. More Info

The MVI94 Modbus Slave Network Interface Adapter can interface up to 8 Rockwell Automation FLEX and/or Integra I/O modules directly with any Modbus Master.

Features and Benefits

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. Each product is shipped with a User Manual detailing its installation and operation.


The 3170-MBS module provides highly configurable Slave capabilities to the Rockwell Automation FLEX and/or Integra platform. The product is frequently used in two general applications, SCADA Slave or as a foreign device interface master. In a SCADA Slave application the module could be used in remote controller racks as is often used in the oil and gas, or wastewater industries.
