PROFINET IO Development Kits Overview

BradCommunications™ allows to develop and market PROFINET products more quickly 2 solutions – IO-Controller

– IO-Device

PROFINET IO Development Kits Architecture USER APPLICATION API System Adaptation

Operating System (thread, interrupt, timer, etc)

BradCommunications™ PROFINET IO Development Kits

The PROFINET IO stack is composed in 3 majors components: Core Stack

Engine IO Data Image

Stack Interface Stack user layers. They should be adapted depending of the hardware and OS

(process, alarm, status)

API Network Adaptation RPC
