More Information

Overview Manuals Channel Modes IO-Link Network Power and Compatibility Application
  • Four channels can be configured independently for IO-Link or standard digital I/O
  • IO-Link operates at 4.8, 38.4, or 230.4 kilobits per second with a 20-metre maximum device cable
  • The module uses 19.2 to 28.8 V DC field power and 100 mA at 5 V DC from POINTBus

1734-4IOL is an Allen-Bradley POINT I/O four-channel IO-Link master module for EtherNet/IP-based POINT I/O stations.

Each channel can operate as an IO-Link master, a standard IEC 61131-2 Type 1 digital input, a standard digital output, or a disabled point, letting one module combine smart devices and conventional signals.

Before installation or replacement, verify the hardware Series, adapter Series and firmware, Logix Designer release, field-power budget, wiring base, port mode, IODD, process-data size, and saved controller project.

Availability, condition, price, and shipping time for 1734-4IOL are confirmed during quotation.

Description
1734-4IOL is an Allen-Bradley POINT I/O four-channel IO-Link master module for EtherNet/IP distributed-I/O stations.

Each port can be configured for IO-Link master, standard digital input, standard digital output, or disabled operation, with three IO-Link data rates and up to 20 metres of device cable.

Before installation or replacement, confirm the module Series, adapter Series and firmware, Logix Designer version, field power, wiring base, port modes, IODD files, process-data layout, and approved project archive.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which IO-Link device revisions are compatible with Allen-Bradley 1734-4IOL?
Allen-Bradley 1734-4IOL operates as an IO-Link Revision 1.1 master and can communicate with both IO-Link V1.0 and V1.1 devices. The master itself cannot be configured to operate as an IO-Link Revision 1.0 master.
Can Allen-Bradley 1734-4IOL store parameters for a replacement IO-Link device?
Yes. When Data Storage is enabled, Allen-Bradley 1734-4IOL stores supported device parameters and can restore them to a replacement device. Data Storage requires an IO-Link V1.1 device that supports this function.
What does Fallback mode do on Allen-Bradley 1734-4IOL?
Fallback mode lets Allen-Bradley 1734-4IOL configure an IO-Link device and then return that device to standard digital-input operation. The controller receives one input bit for the channel while the device is operating in Fallback mode.
How does Implicit Protection Mode affect Allen-Bradley 1734-4IOL?
Allen-Bradley 1734-4IOL enters Implicit Protection Mode when an I/O connection is established. Firmware updates, module resets, channel-mode changes, and IO-Link sensor-configuration changes are rejected until the I/O connection is stopped.
Can Allen-Bradley 1734-4IOL use an IO-Link device without a registered IODD file?
Yes. The device can be added with a generic IO-Link profile. However, Automatic Device Configuration and parameter correlation are unavailable, and device parameters must be accessed through message instructions.
What happens when Exact Match keying fails on Allen-Bradley 1734-4IOL?
Exact Match compares the connected device’s Vendor ID and Device ID with the values configured for the channel. If they do not match, IO-Link communication is not established and Allen-Bradley 1734-4IOL sets the channel’s Keying Fault status bit.
What should be checked before installing Allen-Bradley 1734-4IOL?
Confirm Series, adapter firmware, Logix Designer support, field power, base, channel modes, IODDs, process-data sizes, and the approved project.
