5.5 UNITE IO Server
5.5.1 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 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.
5.5.2 Setup
5.5.2.1 Communication Setup
Figure 79: XWAY-UNITELWAY configuration
If more than one Serial port are available, you must choose on which COM the Unitelway request will be sent.
Baud Rate Select the baud rate applying to your industrial network
Parity
The parity to apply: none / odd / even. This field is set by default to Odd, as in the main cases in a
typical UniTE topology. However, the eWON allows you to define a different parity type (Even or
None), in case this is needful to comply with your industrial network installations.
Stop Bit(s) Number of stop bits
Master Response Timeout
Maximum time the eWON will wait for a valid message from the Unitelway master. This value can be
critical for a correct operation, depending on the responsiveness of the master. A value of 1000
should be selected to guarantee a correct operation.
Rx message timeout (MSEC) Maximum time between a request is posted and the response is received
Tx message timeout (MSEC) Maximum time for a request to be sent
Force UnitelWay V2
If checked, the eWON will initiate a communication in V2 with the devices. When used with a TSX
PLC, this check box can be left unchecked.
ADO
Link address base. The eWON will respond to AD0 and AD0+1 on the Unitelway link.
The eWON will act as an Unitelway slave, it will respond to 2 consecutive link addresses AD0 and
AD0+1, doing this improves the throughput of data across the eWON when acting as a gateway.
Xway Network Station
Address of the eWON on the XWAY network.
When acting as an XIP to Unitelway gateway, the eWON will only respond the XWay network station
defined here. Any XIP frame addressed to another network station will be ignored.
