H2: Auxiliary function outputs to PLC8.8 Programmable output durationBasic FunctionsFunction Manual, 09/2011, 6FC5397-0BP40-2BA0 4338.8 Programmable output durationFunctionUser-specific auxiliary functions, for which the output behavior "Output duration of an OB1 cycle (slowacknowledgement)" was parameterized, can be defined for individual outputs via the parts program guide QU(Quick) for auxiliary functions with quick acknowledgement.SyntaxAn auxiliary function with quick acknowledgment is defined in a part program block with the following syntax:[ extension>]=QU()ExampleDifferent behavior for the output of the auxiliary functions M100 and M200 in a parts program. The outputbehavior of the auxiliary functions is parameterized as follows:• M100- Output duration one OB1 cycle (slow acknowledgment)- Output during motion• M200- Output duration one OB1 cycle (slow acknowledgment)- Output prior to motionThe following figure shows the time sequence of the part program. Please note the time difference during theprocessing of parts program blocks N20 and N30.Program code CommentN10 G94 G01 X50 M100 ;;Output of M100: during the motionAcknowledgment: slowN20 Y5 M100 M200 ;;;Output of M200: prior to the motionOutput of M100: during the motionAcknowledgment: slowN30 Y0 M=QU(100) M=QU(200) ;;;Output of M200: prior to the motionOutput of M100: during the motionAcknowledgement: quickN40 X0N50 M100 M200 ;;;Output of M200: immediate 1)Output of M100: immediate 1)Acknowledgment: slowM171) Without a traverse movement, auxiliary functions are always output to the PLC immediately.
