5.2.6 Non-Safety-Related Functions
5.2.6.1 Measuring Function
• Different measuring functions can be used on the device for controlling system parts, for example. This
enables muting parts to be measured or their size checked, among other things.
• The recorded process data can be accessed via IO-Link.
) can be determined via the measuring function:
• First blocked beam
– Abb. FBB: First Beam Blocked
– Shows the position of the first blocked beam (as viewed from the control panel).
– If the safety field is free: FBB = 0
• Last blocked beam
– Abb. LBB: Last Beam Blocked
– Shows the position of the last blocked beam (as viewed from the control panel).
– If the safety field is free: LBB = 0
• Number of blocked beams
– Abb. NBB: Numbers of Beams Blocked
– The total number of blocked beams in the safety field (including multiple objects)
• Number of cumulated blocked beams (biggest group: NCBB)
– Abb. NCBB: Numbers of Cumulated Beams Blocked
– Total number of blocked beams of the largest object
• Number of objects (NOBJ)
– Abb. NOBJ: Numbers of Objects
– Number of objects in the safety field
