EtherNet/IP Deterministic Network Integration
The 1734-AENTR/B supports EtherNet/IP communication through dual embedded Ethernet interfaces. The adapter can participate in Device Level Ring (DLR) architectures, allowing network path continuity if a single cable segment becomes unavailable. Communication operates at 10/100 Mbps with automatic half-duplex or full-duplex negotiation.
Within POINT I/O installations, the adapter functions as the network interface for up to 63 connected I/O modules. This architecture supports I/O density scaling without requiring a separate network node for each module. Network configuration can be performed through rotary address switches, BOOTP/DHCP services, or static IP assignment methods.
Frequently Asked Questions
Q: Does the 1734-AENTR/B support network redundancy?
A: Yes. The module includes two embedded Ethernet ports and supports Device Level Ring (DLR) configurations for redundant network paths.
Q: How many POINT I/O modules can be connected through one adapter?
A: The adapter supports connection of up to 63 POINT I/O modules on the associated I/O assembly.
Q: Can the module be installed on a standard DIN rail?
A: Yes. The documented mounting method is DIN-rail installation within a control enclosure.
Field Installation Guidelines
-
Verify that the supply voltage remains within the specified 19.2 to 28.8 VDC operating range before energizing the adapter.
-
Install the module on a properly grounded DIN rail inside an enclosure suitable for the environmental conditions.
-
Route Ethernet cables separately from high-voltage motor and drive conductors to minimize conducted and radiated interference.
-
Maintain consistent shield grounding practices throughout the control panel and network infrastructure.
-
Confirm IP address settings before connecting the module to an active EtherNet/IP network.
-
When implementing DLR topologies, verify ring integrity and network diagnostics after commissioning.
-
Follow controller and POINT I/O firmware compatibility requirements before system startup or firmware maintenance activities.
