Modbus/HSE Controller


DFI302 platform multifunctional controller, it is the solution for Modbus applications in the SYSTEM302. The DF89 is a Modbus-HSE controller to provide greater connectivity and flexibility to the system application. Through the HSE network and other DFI302 modules, it is possible the communication between field devices and other industrial protocols, providing greater flexibility to the control strategy projects.

Through the I/O cards and Modbus devices, it is also possible to execute discrete control via relay diagram (“Ladder Diagram”), allowing a single and integrated system. The two Ethernet channels guarantee high availability of control and supervision, and also support redundant operation providing high security level to the process.

Designed for complete distributed control solutions, including configuration tools, network analysis, parameterization, and device’s data acquisition.
