Should I use Modbus for my remote IO?

One of Modbus’s greatest strengths is its simplicity. The protocol is straightforward to understand and implement, requiring minimal overhead. This makes it easy for engineers to configure, set up, and integrate into both new and existing systems.

Connecting Remote IO to PLCs over Modbus is a valuable way to enhance the flexibility and scalability of your automation projects. The Modbus TCP/IP protocol natively provides a robust connection with up to 100 meters of distance between the PLC and the Remote IO, making it suitable for a variety of industrial applications.

Additionally, this distance could be extended even further with the use of network devices to meet the specific needs of your project. By implementing this setup, you not only streamline communication but also ensure that your systems operate efficiently, allowing for seamless expansion and adaptation to future demands.
