Controlling the light ring via URScript

You can control the light ring behavior using the following script commands:

Command

Description

set_baselight_iec()

Default. Sets the light ring to follow IEC 60204-1 standard colors for safety and operational modes.

set_baselight_solid(r, g, b)

Sets the entire ring to a custom color using RGB values (0–255).

set_baselight_off()

Turns the light ring off completely.

 

If you use set_baselight_solid or set_baselight_off in a program, the light ring remains in that state even if the program stops or a protective stop occurs. It does not revert to the standard IEC colors until set_baselight_iec() is called again.

The light ring is purely informational and is not safety-rated. Do not rely on the light ring as an exclusive safety indication.
