Updated 2026-09-17 · LogrobotLM reference

Description

The iPendant firmware consists of Teach Pendant Core Firmware and Browser Plugins. The Browser Plugins, also referred to as application code, can be updated independently of the Teach Pendant Core Firmware. However, the major versions must match. For example, Teach Pendant Core Firmware V6.22xx cannot be used with Browser Plugins V6.31xx. When this happens, the iPendant will detect the problem, post this error, and reconnect in legacy mode. The STATUS Version ID menu can be used to show the versions for the Browser Plugins and the Teach Pendant Core Firmware.

Remedy

Update the whole firmware for the iPendant.
