Abstrakt:
This article describes the practical
implementation of the IO-Link master bridge, which ensure an
interface between IO-Link devices and a main controlling
computer. The main effect of this implementation is a simple
data acquisition system based on a microcontroller that enables
an easy expansion of many connected IO-Link devices.
Concerning universal usage, the communication between the
IO-Link master bridge and the computer works on standard
UART units. Main computer and IO-Link master bridges
interconnection ensure optocouplers. Thus, this method
guarantees galvanic isolation firstly and easy expansion by the
open collector technique secondly.
