I/O to IT/OT Protocol Conversion

Are you still looking for a protocol gateway to translate back and forth between OT and IT protocols? Moxa’s Smart I/O does just what you need by supporting the most often-used protocols for retrieving I/O data. Most IT engineers use SNMP or RESTful API protocols, but IA engineers are more familiar with Operational Technologies (OT), such as Modbus and EtherNet/IP. Moxa Smart I/O makes it possible for both IT and IA engineers to conveniently retrieve data from the same I/O device.


Moxa's multilingual Smart I/O speaks six different protocols, including Modbus/TCP, EtherNet/IP, and Moxa AOPC for IA engineers, and SNMP, RESTful API, and Moxa MXIO library for IT engineers. The Smart I/O retrieves I/O data and converts the data to any of these protocols at the same time, allowing you to get your applications connected easily and effortlessly.

Transporting I/O Data for
Both the OT and IT Worlds

Easily Connect to the IIoT without Installing a Separate Protocol Gateway

Reduce your integration costs by using EtherNet/IP or RESTful APIs to collect data from smart I/O devices without installing an extra protocol gateway to connect to IIoT applications.

Using a RESTful API to Connect Remote I/Os

In this tech note, we explain what a RESTful API is, show why using a RESTful API is easy for web service development, and show how to implement a RESTful API for IIoT applications. Read this tech note to learn how to easily implement your own IIoT applications.

Connecting the Moxa ioLogik E1200 to an Allen-Bradley PLC

This video illustrates a 3-step example of how to connect an ioLogik E1200 Series device with an Allen-Bradley PLC using the EtherNet/IP protocol. Moxa’s ioLogik E1200 Series provides the ideal solution when you need I/O expansion for your PLC. In addition to EtherNet/IP, Moxa’s ioLogik E1200 Series supports 6 different protocols—including Modbus, RESTful API, and SNMP—to support the needs of both OT and IT experts.


This tech note provides a step-by-step example of how to connect an ioLogik E1200 Series device with an Allen-Bradley PLC using the EtherNet/IP protocol. In this example, the Allen-Bradley PLC is the EtherNeT/IP Scanner and the ioLogik E1200 is the adapter. In the first section of the tech note, we explain how to install the ioLogik E1200 Series EDS files in the RSLogix 5000, and in the second section, we explain how to connect the ioLogik E1200 with the Allen-Bradley PLC.
