“The SST DN4 DeviceNet USB interface module has been designed to functionally replace DeviceNet Pro PC Card (PCMCIA) cards,” explains Michael Frayne, embedded product manager for the global market at Molex, adding: “This establishes backward compatibility with DeviceNet Pro (DNP) cards for legacy system connections.”.
Like the SST DN4 NIC cards, the USB interface module utilizes an enhanced FPGA design, characterized by a reduced component count, resulting in a longer lifecycle and higher product reliability. Ideal for real-time data acquisition and control applications, including PC-based HMI/SCADA and control systems, network configuration, and diagnostic and troubleshooting tools, the Molex DN4 USB interface module offers industry OEMs and end users a more reliable and cost-effective solution for industrial communications.
Simultaneous execution of Group 2 server (slave) and client (master) processes enables OEMs and end users to implement control systems that may require full functionality. Ideal for any DeviceNet-based control system, the DN4 supports polling, strobing, change of status (COS), and cyclic input/output messaging. The QuickConnect function of the USB interface module in client (master) mode allows access to devices during boot in less than 500 ms.
The DN4 USB interface module offers multi-network support for all standard DeviceNet transmission speeds (125, 250, and 500 kbaud) and can be used in Control Area Networks (CAN) (2A, up to 1 Mbps). It is compatible with high-speed USB 2.0 and is available with a standard USB Type-B connection.
