HMS Industrial Networks Inc.: New Single-Chip Profinet interface reduces development efforts up to 70%.

Wednesday, October 01, 2008

HMS Industrial Networks has extended its Anybus-IC family with the addition of the Anybus-IC for Profinet IO. The new module is a tiny but powerful embedded single-chip Profinet IO interface, which is certified by the Profibus user organization. It is the latest member of HMS´s Anybus-IC family which already includes interchangeable solutions for Profibus, CANopen, DeviceNet, Ethernet/IP and Modbus-TCP. In a single housing of only 9cm2 in size, the Anybus-IC contains a powerful microprocessor with integrated fast Ethernet controller and a full featured Profinet IO device software stack. The new IC reduces the development efforts needed to design a Profinet IO interface by up to 70%. Additionally, space and power supply requirements are minimized so that even small automation devices such as barcode readers or motor starters can be economically equipped with a Profinet IO interface. The Anybus-IC has a 32-pin dual in line housing and requires only a single 5 Volt power supply. It functions as a standard IO device and supports Profinet conformance class A. Up to 144 bytes of input data and 144 bytes of output data are permitted. The Anybus-IC contains all hardware and software necessary for any automation device to communicate over a Profinet network, only the PHY and the RJ45 Ethernet connector has to be added. When used in intelligent devices that have their own micro-controller, the Anybus-IC is connected via a fast serial TTL interface. The IC handles the entire Profinet IO protocol and offloads the microprocessor from all time-critical communication tasks. In applications with devices without a processor, such as valve terminals, the Anybus-IC has a shift register interface and can control up to 128 direct inputs and outputs. All members of the Anybus-IC family are interchangeable and offer device manufacturers a simple and efficient way to connect small and medium automation devices to all major fieldbus and industrial Ethernet networks with just one development.
