RapID ? Platform - PROFINET Network Interface

2-Port, Class B Connectivity Solution

The RapID Platform Network Interface is a pre-tested module that manages the

industrial protocol and network traffic with a single host processor interface

The interface contains everything needed including the

communications controller, protocol stacks, Flash, RAM, and PHYs. All

PROFINET capabilities are encapsulated on this small form factor device,

and can be integrated into any type of automation equipment from

complex control to a simple sensor or actuator. For applications where

space is limited, the module’s design can be embedded directly into the

field device. The RapID Platform Network Interface connects to a “Host”

processor via a UART or 16-bit Parallel Interface. At the software layer the

Host connects to a “Unified Interface" so other protocols can be used

without changing the host software. PROFINET communication is Class B

certified and passes Net Load Class III. This means your field device

incorporating a RapID Platform Network Interface will operate problem-free with any PROFINET controller and

will never disconnect from the network.

Easy Hardware and Software Integration

The Network Interface can be integrated into a design as either a module or an embedded design. As a

module, the Network Interface plugs into a board using standard 2.54 mm pitch through-hole pins. When

designing-in the module, hardware integration is as easy as connecting Power/Ground/Reset and interfacing

the Host to the UART or 16-bit Parallel interface. The Ethernet

physical interface is ready to plug into the network. Software for

the module is provided as firmware that is resident on the flash.

As an embedded design, the Network Interface hardware

design can be integrated directly using the schematics provided.

Also provided are the Bill of Materials and example layouts to

minimize the hardware design effort. Software for the

embedded design is provided as firmware that is downloaded to

the flash. Whether using the Network Interface as a module or

an embedded design, no software development is required and

there are no license fees or royalties.

Software integration with a Host is also easy. Messages

passed between the Host and Network Interface follow a “Unified Interface” definition. A simple to use,

Innovasic supplied, PC-based tool configures the Network Interface , so the Host only passes parameters

between it and the Network Interface . From this tool, it is also easy to specify how parameters will be passed

to the PROFINET controller using the GSDML file. Since the Host is only passing parameters, the Host software

does not have to change if PROFINET network parameters change or if another Industrial Ethernet protocol is

used. There is also a “sockets” interface that supports direct Ethernet communication. Example C-code is

provided to minimize the software effort for the Host / Network Interface communication.
