U2 it will need to poll the IP address of the WI-I/O 9-U2, The Port Number that is
configured here and the Device ID of the serial device.
Request Pause – Is the delay between serial requests in milliseconds
Response Wait
– Is the serial response timeout in milliseconds – a serial retry will be
sent if a response is not received within this timeout.
Connection Timeout – Is the TCP connection timeout in seconds – if no Modbus/TCP
data is received within this timeout then the TCP connection will be dropped. Set this
field to zero for no timeout.
Maximum Tries – Is the maximum number of request retries that are performed on the
serial port.
Maximum Number of connections
– This is the maximum number of simultaneous
TCP connection that can be made to the TCP Server.
Serial - Expansion I/O
By default the RS485 port will be automatically enabled for “Expansion I/O “, this is to
allow serial expansion I/O modules to be connected with minimal or no module
configuration.
This means that when adding an WEIDMULLER Expansion I/O module/s, e.g. WI-I/O-
EX-1-S-11, WI-I/O-EX-1-S-12, or WI-I/O-EX-1-S-13 to the RS485 port of the WI-I/O 9-
U2, the I/O will automatically be available from within the WI-I/O 9-U2
’s I/O store. See
User Manual for location addresses.
The default Data Rate and Data Format will
be standard 9600, N81 with no Flow Control
which matches the default serial baud rate
and data format of the WI-I/O-EX-1-S serial
expansion module.
Serial parameters can be adjusted for
compatibility or faster serial performance by
adjusting the rates and format and then
selecting the “Save and Activate” Button.
Serial port parameters will also need to be
changed on the expansion I/O module by
using the WI-I/O-EX-1-S Configuration Utility
which can be downloaded from the
Weidmuller Website

Maximum Number of Expansion Modules to Poll
– This is the maximum number of
slave addresses that the WI-I/O 9-U2 will scan or poll. Default is 3. If adding more than
3 x WI-I/O-EX-1-S expansion I/O module or the address used are greater than 3, this
number will need to be increased to match the largest address.
Maximum Number of Connections
– Is the maximum number of simultaneous TCP
connections to the server allowed.
