High Speed Ethernet Controller

DFI302 platform multifunctional controller, the DF75 is the second generation of Smar Logic Controller. It is an HSE controller whose main purpose is to associate the discrete control with continuous control using FOUNDATION FieldbusTM blocks.

Through the I/O cards, it is possible to execute the discrete control via relay diagram (Ladder Diagram), communication among field devices, in addition to Modbus communication.

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.
