Description
3. Product Introduction & Engineering Value
The ANC-100E is a pocket-sized Ethernet-to-DH+ adapter that emulates a ControlLogix backplane containing both an ENET and a DHRIO module.
Engineers use it to give RSLinx Classic, FactoryTalk Linx, Kepware, Ignition, and Wonderware native access to existing blue-hose networks. Auto-baud, auto-polarity, and free-node detection cut commissioning time. Power draws only about 35 mA at 24 V. The unit mounts on DIN rail or sits on a desktop and requires no ladder-logic changes.

5. Field Application & The “Trench” Experience
A Midwest bottling plant still ran three SLC 5/04 processors on a single DH+ trunk. Their only remaining 1784-PCMK card failed during a weekend changeover. The crew needed online access for RSLogix 500 and a path for two new PanelView Plus 7 terminals. An ANC-100E was clipped onto the DIN rail, the blue hose was landed on the Phoenix connector, and a static IP was set. Twelve minutes later every node showed up in RSWho. By Monday morning both PanelViews were reading and writing N7 and B3 files. No chassis, no extra power supply, no program edits.
Specific uses that fit this hardware:
- Batch-weigh system interlocks still on PLC-5 that must feed a new Ignition historian
- Packaging-line case packers using SLC 5/04 with PanelView Standard screens being upgraded to PanelView Plus 7
- Remote pump-station temperature and pressure loops that need occasional RSLogix 5 access over the plant Ethernet
6. Transparency SOP: QA & Testing
- Housing and connector pins inspected for damage or corrosion
- Unit powered across the full 9–24 VDC range while current and LED status are recorded
- DH+ auto-baud and polarity confirmed against known 57.6 k, 115.2 k, and 230.4 k networks
- Ethernet link established and web-configuration page verified
- Live path test performed through RSLinx to actual PLC-5 and SLC 5/04 nodes (read/write of integer and binary files)
- Thermal cycle at temperature extremes followed by full communication re-check
- Firmware and configuration returned to factory defaults before final packaging
7. The Veteran’s Tech Trap Guide
⚠️ Duplicate node address will stop the entire trunk. Even though the unit auto-selects a free node, always double-check the chosen address against every existing PLC, PanelView, and interface card. A collision freezes token rotation.
PRO TIP: The default IP address varies by firmware revision (commonly 192.168.0.230 or 192.168.137.2). Place your laptop on the matching subnet before you try to open the web page. Otherwise the unit looks dead.
⚠️ Auto-polarity fixes swapped wires, but terminators still matter. Missing or incorrect 150 Ω resistors at both ends of a long blue-hose run produce intermittent drop-outs that look exactly like a gateway fault.
8. Dynamic FAQ
Q: Will the ANC-100E work with both RSLinx Classic and FactoryTalk Linx?
A: Yes. It appears as a standard ControlLogix Ethernet driver path in both packages.
Q: How many PanelView Plus terminals can share one ANC-100E?
A: Up to five IP addresses can be assigned (one per DH+ PLC). For reliable messaging, keep the total Ethernet clients low—typically one primary HMI plus a few DH+ nodes.
Q: Does the unit support Remote I/O scanning?
A: No. It is a pure DH+ bridge for programming, messaging, and data access. It does not replace a 1756-DHRIO used for RIO.
Q: What power supply do I need?
A: Any clean 9–24 VDC source. Current draw is under 100 mA, so a small DIN-rail supply is more than adequate.
Q: Is firmware still being updated?
A: Automation Networks continues to support the product. Confirm the latest revision with your supplier when ordering.
Q: What warranty applies to new-surplus or refurbished stock?
A: Functional warranty is standard. Many suppliers offer extended or lifetime coverage on this model—verify the exact terms at time of purchase.
