Product Overview

The Allen-Bradley 2080-USBADAPTER​ is the official Rockwell Automation USB programming and online-monitoring cable for the Micro800 family of programmable logic controllers—including the Micro810 (2080-LC10-xxx), Micro820 (2080-LC20-xxx), Micro830 (2080-LC30-xxx), Micro850 (2080-LC50-xxx), and Micro870 (2080-LC70-xxx). Where the SLC 500 world had the 1747-CP3 (DH-485 RS-232) and the MicroLogix world had the 1761-CBL-PM02 (Mini-DIN to RS-232), the Micro800 generation standardizes on USB: the 2080-USBADAPTER​ carries a Type-A plug for the engineering laptop and a USB 2.0 Mini-B plug for the Micro800 controller’s front USB port, delivering both the CDC (Communications Device Class) data path for Connected Components Workbench (CCW) and, on supported models, a virtual COM port for legacy-tool compatibility. The cable is approximately 2.5 m (8.2 ft) long, shielded, and RoHS/CE compliant, and it draws bus power from the laptop—no external PSU, no separate 24 V feed.At the system level, the 2080-USBADAPTER​ is the primary commissioning path for Micro810 and Micro800 panels: the Micro810 (2080-LC10-12QBB / 2080-LC10-24QBB) is the smallest brick in the Rockwell lineup—no HMI port, no Ethernet, just the front USB + a 3.5 mm serial-like barrel for optional 2080-SERIALLINE (RS-232/485) and the terminal-block I/O—so the 2080-USBADAPTER​ is literally the only way to get CCW onto the unit without adding the 2080-SERIALLINE and a USB-RS-232 dongle. For the larger Micro820/830/850/870, the 2080-USBADAPTER​ competes with Ethernet (on models that have it) and the 2080-SERIALLINE, but remains the go-to for first commissioning, firmware flash (via CCW’s “Update Firmware” wizard), and bench debugging where the panel isn’t cabled for Ethernet yet. The cable enumerates as a USB CDC device on Windows 10/11 and is recognized natively by CCW v4 through v22+; no separate driver install is needed on modern Windows builds that include Microsoft’s USB CDC class driver, though Rockwell bundles a signed INF in the CCW installer as fallback. For SI vans, OEM service techs, and plant maintenance shops that support Micro800-based machines—conveyor zones, packaging auxiliaries, pump skids, lighting-control panels, and Arduino-shield-expanded custom rigs (the Micro810/Micro820 support Arduino Shields via the 2080-UMICRO-1)—the 2080-USBADAPTER​ is the one cable that lives in the laptop bag alongside the 1747-CP3 and 1761-CBL-PM02 for the older Rockwell tiers.

Technical Specifications

Main Features and Advantages

Official Rockwell-specified cable for the entire Micro800 family.​ The 2080-USBADAPTER​ is not a third-party USB-A-to-Mini-B generic—it’s Rockwell’s own SKU, called out in every Micro810/Micro820/Micro830/Micro850/Micro870 user manual as the recommended PC interface. Generic Mini-B cables (phone charger cables, printer cables) will physicallyplug into the Micro800 front port, but many won’t enumerate the CDC class correctly or will drop during firmware flash because the wire gauge and shielding don’t meet the Micro800 port’s impedance expectations. The 2080-USBADAPTER​ shields the differential pair properly and is impedance-matched to the Micro800 front-port PHY, so CCW stays connected through long online-monitor sessions and firmware updates don’t bail at 87%.2.5 m reach covers panel-to-laptop in real-world cabinets.​ A 1 m cable sounds fine on a bench; on a floor-standing NEMA 12 panel with the Micro810 mounted bottom-third and the laptop on a cart, 1 m never reaches. The 2080-USBADAPTER​ at 2.5 m clears the panel door swing, the cart lip, and the tech’s knee. The cable is braid+foil shielded, so routing it alongside 24 V DC homeruns and VFD output trays (briefly, during commissioning) doesn’t CRC-flood the CDC session—though best practice is still “don’t dress comms cable next to VFD output.”Bus-powered, no external PSU, no 24 V feed.​ The 2080-USBADAPTER​ draws from the laptop’s USB port—typically < 100 mA—so there’s no separate wall wart to lose, no 24 V rail dependency, and no “why won’t CCW see the PLC” caused by a dead programming-cable PSU (a classic failure mode on the old 1747-CP3 + 1761-NET-AIC era). For service vans that keep one bag for all Rockwell tiers, the 2080-USBADAPTER​ + 1747-CP3 + 1761-CBL-PM02 covers Micro800, SLC 500, and MicroLogix without carrying three wall warts.CCW-native with firmware-flash support.​ The 2080-USBADAPTER​ carries the CDC command set that CCW uses for upload/download, online edit, data-monitor, and firmware update. For Micro810 specifically (2080-LC10-12QBB / 2080-LC10-24QBB), the front USB is the onlynative programming path short of adding the 2080-SERIALLINE and a USB-RS-232 dongle—there’s no Ethernet on the LC10, no DH+, no RS-232 D-shell on the brick itself. So the 2080-USBADAPTER​ is not just “a cable” for the Micro810; it’s the commissioning lifeline. CCW’s “Go Online,” “Upload,” “Download,” “Verify,” and “Update Firmware” all ride the 2080-USBADAPTER​ without any driver-mapping gymnastics—plug in, CCW > Communications > Find, the 2080-LC10 appears, go.Cross-family compatibility protects the spare budget.​ One 2080-USBADAPTER​ covers the whole Micro800 line: a van that supports a Micro810 pump skid (LC10), a Micro820 OEM packaging aux (LC20), a Micro830 conveyor zone (LC30), a Micro850 palletizer cell (LC50), and a Micro870 test-stand (LC70) only needs this one USB cable SKU on the spare shelf. Compare that to the SLC/PLC-5/MicroLogix era where DH-485, DF1, DH+, and Ethernet each wanted a different physical path—Micro800 simplified that to USB + Ethernet + Serial, and the 2080-USBADAPTER​ is the USB leg.

Application Field

The 2080-USBADAPTER​ is concentrated in three contexts, all tied to the Micro800 installed base. First, OEM machine commissioning—the Micro810 (2080-LC10-12QBB with 12 I/O, 2080-LC10-24QBB with 24 I/O) is a favorite brick for conveyor-zone auxiliaries, pump skids, lighting-control panels, and small packaging-machine heads because it’s the cheapest Rockwell-logic device that still runs ladder (with CCW) and supports Arduino-Shield expansion via the 2080-UMICRO-1 carrier. The OEM tech unboxes the machine, plugs the 2080-USBADAPTER​ into the LC10’s front Mini-B, connects Type-A to the laptop, fires CCW, downloads the application, toggles the HMI-less LCD (the LC10 has a 1-line LCD + keypad), and the machine is live. No Ethernet to configure, no IP to assign, no DHCP—just USB. For machines that ship 50+ units a year, the 2080-USBADAPTER​ lives in the commissioning kit and gets used 50 times a year.Second, plant maintenance & retrofit​ on Micro800-based skids—water-treatment lift stations, HVAC plant-loops, small-material-handling zones—where the original OEM spec’d a Micro810 or Micro820 because the I/O count was < 24 and the budget couldn’t carry a MicroLogix 1400 or CompactLogix. The plant tech keeps a 2080-USBADAPTER​ in the truck because the skid panel doesn’t have an Ethernet drop labeled “maintenance,” and even if the Micro820/Micro850 on the skid has Ethernet, the maintenance VLAN might not be routable from the truck’s Wi-Fi. USB is air-gapped, always works, no IT ticket.Third, lab/test-stand and educational rigs—the Micro810/Micro820’s Arduino-Shield compatibility (via 2080-UMICRO-1) makes it popular in university mechatronics labs and OEM prototype shops where they want Rockwell ladder for the “real PLC” part but Arduino-shield sensors (IMU, GPS, LoRa, custom PCB) for the “prototype” part. The 2080-USBADAPTER​ is on the bench permanently, plugging into whichever LC10/LC20 is under test that week. For SI companies that still support SLC 500 and MicroLogix on the main lines but are quoting Micro810/Micro820 for the auxiliaries, the 2080-USBADAPTER​ is the new cable that joins the 1747-CP3 and 1761-CBL-PM02 in the field bag.
