Job planning
5-28 Programming Manual, 03/2006 Edition, 6FC5398-2BP10-1BA0
Parameters
MEASA Measurement with deletion of distance-to-go
MEAWA Measurement without deletion of distance-to-go
MEAC Continuous measurement without deleting distance-to-go
Axis Name of channel axis used for measurement
Mode Two-digit setting for operating mode consisting of
Measuring mode (ones decade) and
0: Mode 0: Cancel measuring job
1: Mode 1: Up to 4 different trigger events can be activated
concurrently. Trigger events
2: Mode 2: Up to 4 trigger events can be activated consecutively
3: Mode 3: Up to 4 trigger events can be activated consecutively
but no monitoring of trigger event 1
on start (alarms 21700/21703 are suppressed)
Note: Mode 3 not possible with MEAC
Measuring system (tens' decade)
0 or no setting: active measuring system
1: Measuring system 1
2: Measuring system 2
3: Both measuring systems
TE 1…4
Trigger event
1: rising edge, probe 1
-1: falling edge, probe 1
2: rising edge, probe 2
-2: falling edge, probe 2
Measurement
memory
Number of FIFO (circulating storage)
Example of measuring with delete distance-to-go in mode 1
(evaluation in chronological sequence)
a) with 1 measuring system
