Extremely Fast and High-capacity Data
Links Compared to Previous FA Networks
Large Data Transfers with High Reliability.
High-speed and High-capacity
Data Links
From manufacturing recipes and information
on interlocks between processes to production
data, any type of data can be exchanged
at high speed and at the optimal timing.
Communications performance is vastly
improved over OMRON’s Controller Link and
FL-net networks.
Automatic Address Allocation Is Expanded
to Up to 240 Kwords, Enabling Allocation of
Large Amounts of Data.
The memory size of the EM Area for automatic
address allocation in CX-Programmer symbol tables
has been expanded to a maximum of 240 Kwords.
When a tag is automatically allocated, data link
design and access from the host are enabled with
no need to be conscious of addresses. Moreover,
bits can be force-set/reset in the areas in which
data is automatically allocated.
Peripheral Devices (such as Cables, Hubs, and
Wireless Devices) Can Be Used With Universal
EtherNet Technology.
The convenience of a global standard at your
fi ngertips.
» Using Universal EtherNet Reduces Network
Installation and Wiring Costs.
» FA Wireless LAN Makes Mobile Control Easy,
with No Need for Rewiring when
Changing Layout.
