Operation Meaning
B5 Tool orientation: Surface normal vector
for end of block
B_AND Bit AND
B_OR Bit OR
B_NOT Bit negation
B_XOR Bit exclusive OR
BAUTO Definition of the first spline section by
means of the next 3 points
BLOCK Together with the keyword TO defines
the program part to be processed in an
indirect subprogram call
BLSYNC Processing of interrupt routine is only to
start with the next block change
Natural transition to first spline block
3)
BNAT
BOOL Data type: Boolean value TRUE/FALSE

BOUND Tests whether the value falls within the
defined value range. If the values are
equal, the test value is returned.
Fast non-smoothed path acceleration
3)
BRISK
BRISKA Switch on brisk path acceleration for the
programmed axes
BSPLINE B-spline
BTAN Tangential transition to first spline block
C Axis name
C2 Tool orientation: RPY or Euler angle
