The numbers indicate the position of the bit for the corresponding device.
0:
Device is not present
1:
Device is present

Vendor Specific Object 9 - Device Colors at switch off OSSD 1
Read only.
This object contains the colors for all devices as well as additional information for
all release circuits at the time of the last switch-off of Release Circuit 1. Also sent
is which devices belong to Release Circuit 1. The information is retrieved using
the command "Get Device Colors at switch off" from the safety unit.
