What does the Group Mask indicate when it shows [ 1, *, *, *, *, *, *, * ]?

The Group Mask is a feature used in FANUC robots to manage the active statuses of different robot groups during programming and operation. When the Group Mask displays [1, *, *, *, *, *, *, ], it signifies that only Group 1 is active, while the asterisks () in positions 2 through 8 indicate that those groups are not active at this time.

In a practical sense, the Group Mask is used to control which groups of robots can perform actions simultaneously or are considered during execution of commands. In this case, since only the first position of the mask is set to '1', it explicitly confirms that Group 1 is the only group enabled to perform the designated operations, allowing for focused and controlled execution while ensuring that resources are not overstretched by inactive groups.
