In the case of MEAN WELL, the Modbus RTU protocol is used for communication between power supplies, while Modbus TCP/IP is used to transfer data between these supplies and the end device, acting as an interpreter that translates one protocol to another, commonly known as a gateway. The following table describes the key differences between MEAN WELL's Modbus RTU and Modbus TCP/IP:
All MEAN WELL intelligent controllers, including the CMU2C and CMU2E models, use Modbus TCP/IP as the external communication interface, allowing customers to focus on integrating their systems without needing to invest time in understanding the details of power supply control.
The following table lists the models that support Modbus RTU and Modbus TCP/IP:
All these devices are included in the OLFER Electronics catalog and distributed in Spain and Portugal.
