Features:
- Three-port tap: two ring links and one device path serve a DLR node
- Legacy topology role: the port assignments preserve the installed ring architecture
- Documented successor: 1783-ETAP3T is the manufacturer-listed functional replacement
1783-ETAP inserts a non-ring device or local segment into an EtherNet/IP Device Level Ring through a three-port tap arrangement.
Its two ring interfaces carry the resilient path, while the third connection serves the attached equipment and should remain separately identified.
Migration to the current tap changes more than catalog availability, because software, diagnostics, addressing, and physical fit must be reviewed.
Apter Power can review 1783-ETAP topology, Series, port assignment, existing condition, official records, and migration scope before quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
- Ring direction A: retain the documented connection to one adjacent ring node.
- Ring direction B: preserve the second path to the opposite ring neighbor.
- Device connection: keep the local equipment port out of the ring-link assignment.
- LED evidence: capture power, network, and port indications before removal.
- Ring state: distinguish a local cable fault from a supervisor or ring-wide event.
- Physical isolation: test one cable or endpoint at a time because the tap has limited local diagnostic depth.
- Functional successor: evaluate 1783-ETAP3T with its current official instructions.
- Software boundary: verify that engineering tools support the new tap and diagnostics.
- Cutover proof: compare supply, wiring, mounting, addressing, and controlled ring recovery.
- Legacy DLR device attachment: connect a local EtherNet/IP device to an installed ring.
- Ring expansion point: retain the approved two-direction topology while serving one local path.
- Managed migration project: document the legacy tap before introducing the current functional replacement.
