Wireless I/O
WI-I/O-9-U2 Meshed Multi I/O and Gateway
Quicker, more cost effective commissioning.
Configuring and commissioning time/effort on the WI-I/O-9-U2
has been designed for ease of customer use and cost savings
during commissioning. The configuration utility allows for simple
nomination of I/O points origin and destination with automatically
detecting and routing the most efficient path to the destination
node. This is complemented by periodic interrogation for optimal
path verification, quick recovery of network communications and
automatic detection of expansion I/O (Weidmuller’s WI-I/O-EX-1-S).
It also incorporates efficient ‘change of state’ radio communications and user configurable I/O or register periodic reporting of link
status (ie update time). All combine to ensure the user is in charge
of network communications.
Radio network efficiency and commissioning of the WI-I/O-9-U2
into legacy process control/automation networks is aided with
block mapping and block messaging technology.
Block mapping technology allows end-users to gather related,
non-contiguous data points/registers, into a single radio message
structure and scatter these points at receiving devices for ease
of integration (eg PLC logic, SCADA tags).
Block Mapping Technology
1 Message
Block mapping technology enables non-contiguous data to be transferred between network
devices reducing re-programming time and associated costs.
Configuration is user friendly by nominating and labelling origin and destination points, and
IP-based addressing finds the most efficient route.
Remote/local configuration, upgrade and analysis.
Weidmuller’s IP-based addressing further aids in cost reduction
providing remote analysis and/or upgrade. A user may perform
remote or local over the air re-configuration and interrogation of
nodes for diagnostics and firmware upgrade. User nominated
localized referencing of I/O and system wide network viewing
aids in fault analysis and exporting/printing of node configuration
is supported.
Block mapping technology is complemented by block messaging
technology allowing end users to select continuous, related, I/O
and registers for forwarding to receiving devices in a single
message. Both block mapping and block messaging combine
with highly efficient ‘change of state’, dense capacity radio
messaging capabilities in providing scalable system design for
ever growing application needs.

Process network
Block messaging communicates continuous blocks of data improving the efficiency of radio
band use and even more scalable network design.
Remote LAN
Cost effective, distance IP based mesh networks.
The WI-I/O-9-U2 combines distance, 900MHz, IP mesh communications with ease of configuration, local/remote over the air
re-configurability, firmware upgrade and diagnoses of nodes in
the network.
Featuring Weidmuller’s IP-based addressing technology with
its innovations in network communications efficiency, the
WI-I/O-9-U2 provides for scalable network design for
process control and automation base applications.
