Description
The 2080-USBADAPTER is the official Allen-Bradley (Rockwell Automation) USB programming cable/adapter for the Micro800 family of programmable logic controllers, including the Micro810 (2080-LC10-), Micro820 (2080-LC20-), Micro830, Micro850, and Micro870 series. It features a standard USB Type-A connector for the host PC and a USB 2.0 Mini-B connector that plugs directly into the front programming port on any Micro800 controller, providing point-to-point communication for project download/upload, online monitoring, firmware flashing, and initial IP configuration—all powered through the USB bus without external supply.
Application Scenarios
Imagine a panel builder commissioning a new stand-alone labeling machine controlled by an Allen-Bradley Micro810 (2080-LC10-12QBB) with no Ethernet port. The only way to perform the first program download, set the real-time clock, and flash the firmware to match the version used in CCW (Connected Components Workbench) is through the onboard Mini-B USB port. The technician connects the 2080-USBADAPTER between a laptop and the Micro810’s front port; Windows auto-enumerates the FTDI-based USB-to-serial bridge, CCW detects the “2080-USBADAPTER” communication driver, and within moments the application is downloaded and the machine is running. Later, during a troubleshooting visit, the same 2080-USBADAPTER allows live online monitoring of timer presets and I/O forcing directly from the panel—even when the machine’s Ethernet network is isolated behind a managed switch with no DHCP. The 2080-USBADAPTER solves the field engineer’s core pain point: a guaranteed-compatible, driver-supported, plug-and-play link between modern Windows laptops (which have long abandoned serial ports) and the entire Micro800 controller lineup for both green-field commissioning and brown-field diagnostics.
Parameter
| Main Parameters | Value / Description |

Technical Principles and Innovative Values
- Innovation Point 1 – Native CCW Integration via FTDI VCP Enumeration: The 2080-USBADAPTER incorporates an FTDI USB-to-UART bridge recognized by Windows as a Virtual COM Port with Allen-Bradley’s vendor ID. Connected Components Workbench auto-detects the “USB” communication path in its Communications menu—no manual COM-port guessing required. This contrasts with generic Mini-B cables that may physically fit but fail to enumerate correctly in CCW, saving valuable commissioning time.
- Innovation Point 2 – Single-Cable Commissioning for Micro810 & Micro820 (Non-Ethernet Models): Entry-level Micro810 and base Micro820 controllers have no built-in Ethernet port; the 2080-USBADAPTER is the primaryengineering interface for these units—used not only for program transfer but also for setting the RTC, viewing fault codes, and performing firmware upgrades via ControlFLASH (Micro800 edition) or CCW’s built-in firmware tool. One cable covers all these tasks across the entire Micro800 range.
- Innovation Point 3 – Bus-Powered & Hot-Pluggable for Field Diagnostics: The 2080-USBADAPTER requires no external power and supports hot-plug connection/disconnection. A field technician can unplug it from a panel-mounted Micro830 or Micro850 and reconnect to a laptop mid-shift without powering down the controller (though a brief communication interruption occurs). This facilitates rapid “plug–monitor–unplug” troubleshooting cycles during production without disturbing machine operation.
- Innovation Point 4 – Shielded Construction for Industrial EMI Environments: Unlike low-cost consumer Mini-B cables, the 2080-USBADAPTER uses braided shielding and ferrite suppression components to maintain signal integrity in electrically noisy panels adjacent to VFDs or contactors. This reduces the risk of corrupted downloads or intermittent comm drops that could force a second attempt during critical start-up windows.
