## **periNODE Modbus Single Pair Ethernet to Modbus RTU adapter** 

The _periNODE Modbus_ connects existing Modbus RTU devices to the IT‐based infrastructure via Single Pair Ethernet. 

It makes Modbus RTU devices CRA compliant through state‐of‐the art security measures while adding key features like remote firmware updates, au‐ tomatic device discovery as well as a RESTful API for automated access. 

## **Key Features** 

- Fully operational with One Cable 

- Integrated Software Stacks: TCPIPv6, mTLS, HTTPs, RESTful API 

- Integrated WebUI & RESTful API 

- Based on _sève OS_ , an Operating System for Things 

- Customizable Firmware 

- On device value transformation (Polyno‐ mial calculation)
