Profinet RapID™ Platform Network Interface
Connectivity Solution for 2-Port, Class B Devices
www.innovasic.com
The RapI D P lat f orm Network Interface is a complete Profinet Industrial Ethernet
interface available as a module or embedded design
The interface contains everything needed including the communications
controller, protocol stacks, Flash, RAM, and analog driver so the user does not need to
know anything about the Profinet protocol. 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 small form factor
applications the module’s design can be integrated directly into the field device. The
RapID Network Interface connects to a “Host” processor via a UART or 16-bit Parallel
Interface. Profinet communication has been Class B certified at an accredited Profinet
Interface Center and tested on the bus with numerous applications to provide
problem-free operation with virtually any Profinet controller.
Eas y Hardwa re and Software Integration
The RapID Network Interface can be integrated into a design as either a module or an embedded design.
As a module, the RapID 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 processor 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 RapID Network Interface
connects to a board design 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 RapID 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 processor is also easy.
Messages passed between the Host and RapID Network Interface follow a common interface definition when
using either the UART or 16-bit Parallel interface. This interface simplifies communication for sending or
receiving cyclic, acyclic data and alarms. Example C-code is provided to minimize integration effort on the
Host.
Easy Network Integration
RapID Network Interface comes pre-loaded with the latest firmware for Profinet Class B communication
and includes PriorityChannel™ technology to ensure reliable, real-time network performance. It is Class B

certified and includes support for the Link Layer Discovery Protocol (LLDP)
so controllers can identify the devices attached to the network. Also
included is the Simple Network Management Protocol (SNMP) along with
the required Management Information Bases (MIBs) to support network
configuration and diagnostics. The two protocols work together so
devices can be easily added or removed from the network. When a
device is added to a network, it is sometimes useful to retrieve
information directly from the device. A Web Server is provided for this
purpose. The server can be customized to show device and company-
specific information.
A GSDML file is required for Profinet. This file describes a device’s capabilities to the controller. The
example GSDML file provided can be tailored to describe the exact features of the final product.
Easy Evaluation, Fast P roduct Developme nt
The Evaluation Kit available for the RapID Network Interface provides quick assessment for interfacing a
Host processor to the module. Simply connect the Host processor development board to the RapID Network
Interface evaluation board via the UART or 16-bit Parallel interface. Once Host-side communication is
established, Profinet communication can be evaluated using 3rd-Party, PC-based Tools. The communication
path between Host processor and Profinet controller can be completely verified before integrating the module
into the actual automation equipment hardware.
