Allen-Bradley 1783-ETAP1F – EtherNet/IP In-Line Network Tap | Stratix / ArmorStratix Platform
Engineering Background
Modern industrial Ethernet networks demand non-intrusive monitoring and diagnostics without disrupting live production traffic. The 1783-ETAP1F addresses this requirement as a passive, in-line EtherNet/IP tap purpose-built for Rockwell Automation control architectures. It enables full-duplex packet capture on both network segments simultaneously, giving automation engineers real-time visibility into control-layer communications without inserting additional latency or single points of failure into the network path.
Product Positioning
The 1783-ETAP1F is the preferred diagnostic access point for Allen-Bradley EtherNet/IP networks running ControlLogix, CompactLogix, and GuardLogix controllers. It is deployed by network engineers and OEM integrators who require deterministic, non-disruptive packet capture at the device level — particularly in safety-critical and high-availability manufacturing environments where network downtime is not an option.

Engineering Advantages
- Zero Network Impact — Passive tap architecture introduces no additional latency, jitter, or packet loss to the monitored EtherNet/IP segment.
- Fail-Safe Pass-Through — Network traffic continues uninterrupted even if the tap loses power, eliminating single-point-of-failure risk.
- Full-Duplex Capture — Simultaneously captures both transmit and receive streams on the monitored link for complete bidirectional visibility.
- Native EtherNet/IP Integration — Designed and validated within the Rockwell Automation Integrated Architecture, ensuring seamless compatibility with Studio 5000, RSLinx, and FactoryTalk diagnostics tools.
- Compact DIN-Rail Form Factor — 22.5mm wide profile minimizes panel real estate; installs directly alongside Stratix switches and 1783-series devices.
- Deterministic Monitoring — Supports time-sensitive diagnostics on networks running CIP Motion and CIP Safety without protocol interference.
System Architecture & Signal Flow
The 1783-ETAP1F is inserted in-line between two EtherNet/IP network nodes (e.g., between a Stratix 5700 switch port and a ControlLogix EN2T communication module). The tap passively copies all traffic from both the A-side and B-side ports to the monitor port, where a network analyzer, protocol analyzer (e.g., Wireshark with EtherNet/IP dissector), or Rockwell’s FactoryTalk Network Manager can capture and decode CIP packets in real time.
Typical Wiring Path: Switch Port → [1783-ETAP1F Port A] ↔ [1783-ETAP1F Port B] → Controller EN2T | Monitor Port → Analyzer Laptop / SPAN Collector
Power is supplied via the 24V DC terminal block. The device requires no IP address configuration and presents no management interface — it is fully transparent to the network.

Technical FAQ
Q: Does the 1783-ETAP1F require any configuration or IP address assignment?
A: No. The tap is fully passive and transparent. It requires only 24V DC power and no network configuration whatsoever.
Q: Will inserting the tap affect my EtherNet/IP RPI (Requested Packet Interval) or cause connection timeouts?
A: No. The passive tap introduces negligible propagation delay (sub-microsecond) and does not modify, buffer, or retransmit any packets. CIP connection parameters are unaffected.
Q: Can I use this tap on a CIP Safety network?
A: Yes. The 1783-ETAP1F is protocol-agnostic at the physical layer and will pass CIP Safety frames without modification. It does not affect the safety integrity of the network.
Q: What is the difference between 1783-ETAP1F and 1783-ETAP2F?
A: The 1783-ETAP1F provides one monitor port (copper RJ-45). The 1783-ETAP2F provides two independent monitor ports for simultaneous dual-analyzer capture. Select based on your diagnostic workflow requirements.
Q: Is this product compatible with Rockwell’s FactoryTalk Network Manager?
A: Yes. The monitor port output is standard Ethernet and is fully compatible with FactoryTalk Network Manager, Wireshark, and any IEEE 802.3-compliant packet analyzer.
Q: Do you provide an export license or certificate of origin?
A: Yes. Commercial invoice, packing list, and certificate of origin are provided with all international shipments. ECCN classification and export license documentation available upon request.
