6.5 UNITE IO Server
6.5.1 Introduction
The eWON RS485 link can be configured as an UNITELWAY SLAVE INTERFACE. When the BaudRate in the UNITE IO Server is set to a value
different than "Disabled", the Unitelway slave module in the eWON will be enabled.
This Unitelway slave provides 2 features:
• Poll items in a Unitelway capable device.
The device can be the Unitelway master itself or a device addressable through the Unitelway master on the XWay network.
• Forward XIP requests from TCP/IP XIP to Unitelway bus and thus, act as a gateway between XIP and Unitelway.
Using that feature, it is for example possible to access a PLC connected to the eWON’s Unitelway link by connecting PL7PRO
using the XIP driver started with the eWON IP address as destination.
