HSE/PROFIBUS 1DP and 4PA controller

Multifunctional controller of DFI302 platform with PROFIBUS - High Speed Ethernet gateway capability. It is an innovative market solution that eliminates the need for couplers or gateways DP/PA. The DF97 has one PROFIBUS-DP channel, and Class 1 and 2 master capabilities which allows cyclic access for control and acyclic access for configuration and maintenance. It also has two 10/100 Mbps Ethernet channels, one serial port, four PROFIBUS-PA channels, function blocks and ladder logic execution capabilities. Its extended functionalities allow communication between PROFIBUS DP and PA field devices, besides Modbus communication. Additionally it has system control capability (HOST) for conventional I/O as a PLC.

The DF97 is designed for complete distributed control solutions, including configuration tools, network analysis, parameterization, and device’s data acquisition.
