Industrial Switching Hubs

Industrial Switching Hubs
W4S1Provides the environmental resistance and
functionality required in factory automation
built around Industrial Ethernet communications.
Environmentally Resistant and Highly Reliable
Ethernet Communications for Production Sites
The W4S1 Switching Hub from OMRON is a low-cost, unmanaged switch that does not require software settings to maintain superior
reliability and consistent control data performance on an Ethernet/IP network. It can be used with confidence because it carries a brand
name well known at production sites and because it is backed by OMRON’s total support package for products ranging from PLCs to
switching hubs.
Environmentally Resistant
Perfect Fit for Factory Automation Environments
Tough environmental resistance assures users that the W4S1 Switching Hub can perform in any
environment where PLCs and robots are found. Add to this simple DIN track mounting and well-thought
out cable mounting angles and the result is a significant reduction in the man-hours and space
requirements for control panel installation.

Highly Reliable
Enhanced Network Reliability
The W4S1 Switching Hub is an unmanaged switch that is fully capable of failure detection and broadcast
storm detection. It improves network reliability by notifying users immediately via contact outputs and
LED indicators when an error occurs to quickly pinpoint the location of the error.

Broadcast Storm Detection and Suppression
The W4S1 Switching Hub detects and suppresses broadcast storms that occur
when switches are accidentally connected in a loop.

dicators
Broadcast storms that
exceed the threshold are
detected and removed.

Maintaining EtherNet/IP Performance
Quality of Service (QoS) without Support Software
The QoS (packet prioritization control) for EtherNet/IP ensures high-speed delivery
of control data even if it is dispersed among images and similar data-intensive
applications. And complex software settings are eliminated because QoS can be
enabled with a DIP switch setting.
