616
Name of channel axis used for measurement
Two-digit (xx) number indicating the operating mode (measuring mode and meas‐
uring system)
Units decade: Measuring mode
Specifies whether the trigger events are to be activated in chronological or pro‐
grammed order.
x0 Cancel measuring job.
x1 Up to 4 different trigger events can be activated simultaneously.
x2 Up to 4 trigger events that can be activated successively.
x3 Up to 4 different trigger events can be activated in succession, but there is
no monitoring of trigger event 1 at the start (alarms 21700/21703 are sup‐
pressed).
Note:
MEAC does not support this mode.
Tens decade: Measuring system
Specifies the measuring system with which measuring is to be performed.
0x (or no specification)
1x
2x
3x
Trigger event to initiate measurement
Type: INT
Range of val‐ -2, -1, 1, 2
ues:
(+)1 Positive edge of probe 1
-1 Negative edge of probe 1
(+)2 Positive edge of probe 2
-2 Negative edge of probe 2
Note:
If the measuring process is performed with two measuring systems, a maximum of
two trigger events can be programmed (positive or negative edge). The measured
values of both measuring systems are acquired for both the trigger events.
Number of FIFO (circular buffer)
Active measuring system
Measuring system 1
Measuring system 2
Both measuring systems
Comment
; Measuring in mode 1 with active measur-
ing system. Wait for measuring signal
with positive/negative edge from probe 1
for travel path to X=100.
