eWON 500-2001-4001-4002 User Guide - IO Servers Configuration
eWON 500®2001®4001®4002® Version 4_3_0 - User Guide - 10/5/05 - ©ACT'L sa - Page 87
The following parameters can be modified:
Important: When there are multiple IO servers potentially using the serial line, the unused IO server must select "DISABLED" for
the unused IO server baudrate.
Example: if Modbus and UniTE IO servers are available, at least one of them must have the baudrate configured to "Disabled".
If not, one of the IO servers will not be able to use the serial line and it will be disabled, with an error written in the event log.
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, 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 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 (MSEC)
If checked, the eWON will initiate communication in V2 with the devices.
When used with a TSX PLC, this check box can be left unchecked.
ADO
Link address base. 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.
