Which installed system position is intended for BWU3274?

Install BWU3274 only in the documented Bihl+Wiedemann AS-Interface safety position and verify the complete catalog marking against the approved hardware list.

Which companion hardware must be matched to BWU3274?

Match BWU3274 with two AS-i networks and PROFINET controller, including the documented carrier, cable and project identity.

Which electrical value must be verified before wiring BWU3274?

Verify safe local inputs: 3 x 2. Do not transfer limits from another catalog number.

How should the configuration be preserved when replacing BWU3274?

Record the as-found position, conductors, addressing and software revision, then restore only the approved Bihl+Wiedemann AS-Interface safety configuration.

Which isolation and handling checks apply to BWU3274?

Isolate the documented supply and field energy, use ESD controls and protect the keyed connectors before handling BWU3274.

How should an engineer commission BWU3274?

Power up in a controlled sequence, review device and host diagnostics, then prove the intended as-i safety gateway function.

Can BWU3274 replace a visually similar module without further checks?

No automatic substitution is assumed; compare the full catalog number, interfaces, fieldbus and approved system revision.

Information

Overview Manuals Common Applications Product Precautions

Bihl+Wiedemann BWU3274 is asi-3 profinet gateway with integrated safety monitor. It links two AS-Interface networks to PROFINET and integrates configurable safe input monitoring and release circuits.

Controls two AS-i networks
Connects the installation to PROFINET
Provides three dual-channel safe inputs
Offers six configurable release circuits

BWU3274 operates with two AS-i networks, PROFINET controller, ASIMON360 safety configuration, approved safe sensors and actuators.

Engineered applications include AS-i safety gateway, Dual-network machine safety, PROFINET safety integration, Gateway and monitor renewal.

Important Notice: Export the ASIMON360 configuration, record AS-i addresses and PROFINET identity, then repeat all release-circuit safety tests.

The first document presents model-specific engineering data. The second provides a separate installation, connection, commissioning and acceptance workflow.

AS-i safety gateway

Concentrates two AS-i segments into one gateway.

Dual-network machine safety

Transfers process data to a PROFINET controller.

PROFINET safety integration

Evaluates local safe inputs and release logic.

Gateway and monitor renewal

Restores the validated gateway and monitor configuration.

Read the applicable Bihl+Wiedemann instructions before work. Verify BWU3274 and the installed Bihl+Wiedemann AS-Interface safety configuration.

Verify the full BWU3274 marking and its assigned Bihl+Wiedemann AS-Interface safety position before work.

Place the connected machine or process in the approved maintenance state.

Isolate the applicable supply and as-i process/safety data mapped to profinet with safe release outputs field energy before disconnecting conductors.

Record connector, conductor, address and software identities before removal.

Use ESD controls and protect keyed interfaces, exposed contacts and electronic assemblies.

Confirm the installed two AS-i networks and PROFINET controller against the approved project.

Restore power in a controlled sequence and review device, network and host diagnostics.

Prove the intended as-i safety gateway function and retain the final test result.
