as required.
;-------------------------------------------------------------------------------
;VARIABLES FROM/TO PLC:
;IW0B00 is bag length
;IW0B01 is speed (bag/min)
;IW0B02 is a bitwise word to give the bits to start (b0) and the confir-
mation
; than the cutter is in the STOP position (b2)
;IW0B03 is the expected distance to move after the mark
;OW0BA0 Gives the START order to the cutter (rising edge)
;OTHER VARIABLES:
;MW0006 is the overflow value of the position, depends on the axis
settings and
; must be higher than the maximum bag length
;MW0005 is the Offset value that must be applied to the workpiece co-
ordinate to
; start from zero position.
;MW0002 is the maximum speed of the bag calculated in the sub-pro-
gram to match
; the cycle.
;---------------------------------------------------------------------------------
;The example shows:
; - Use of sub-programs
; - Simple calculation
; - Parameter writing
; - Use of movements with registration
