04 / SYSTEM REQUIREMENTS
EtherNet/IP Integration
The module is designed for EtherNet/IP systems. The official manual specifies the following adapter and software requirements.
B
Series B Adapter
1734-AENT / 1734-AENTR with firmware 5.012 or later
C
Series C Adapter
1734-AENT / 1734-AENTR with firmware 6.011 or later
SW
Engineering Software
Studio 5000 Logix Designer, version 20 or later
IO-Link device integration can use Generic, IODD Basic or IODD Advanced methods, depending on the device and configuration requirements.
05 / FIELD APPLICATION
Application & Failure Scenarios
Where field connectivity meets machine availability.
◎
APPLICATION 01
IO-Link Sensor Networks
Used in POINT I/O distributed control architectures to connect IO-Link-enabled sensors and field devices to an EtherNet/IP controller.
⌁
APPLICATION 02
Discrete Signal Integration
Suitable for applications requiring configurable standard digital input and output channels alongside IO-Link communication.
↻
APPLICATION 03
Maintenance Replacement
Typically searched when an existing module has communication faults, channel errors, configuration problems or hardware failure.
PRODUCTION CONTINUITY
When field communication is interrupted
A failed master module or unavailable field communication can interrupt sensor data acquisition and associated control sequences. Depending on the machine architecture, this may affect production monitoring, interlocks and automated operations until communication is restored.

08 / PRODUCT QUESTIONS
Frequently Asked Questions
01
Can the four channels operate in different modes?
Yes. Each channel can be individually configured as IO-Link, standard digital input, standard digital output, Fallback or Disabled. Mixed configurations are supported.
02
Which IO-Link device revisions are supported?
The master operates using IO-Link revision 1.1 and is compatible with both V1.0 and V1.1 IO-Link devices. The master itself cannot be configured to operate as an IO-Link V1.0 master.
03
Which software and EtherNet/IP adapters are required?
The documented system requirements specify Studio 5000 Logix Designer version 20 or later, together with supported 1734-AENT or 1734-AENTR Series B or Series C adapters and their corresponding minimum firmware revisions.
04
Is an IODD file required for every IO-Link device?
No. Generic integration is available without an IODD file. IODD Basic and IODD Advanced integration require a registered device description file, with Advanced integration intended for supported Rockwell Automation and Technology Partner devices.
