Measuring mode
The measuring mode specifies whether trigger events must be activated in parallel or
sequentially in ascending sequence and defines the number of measurements to be taken.
● Units decade (measuring mode)
● Tens decade (measuring system)
Trigger event
A trigger event comprises the number of the probe and the trigger criterion (rising or falling
edge) of the measuring signal.
1 = rising edge of probe 1
-1 = falling edge of probe 1
2 = rising edge of probe 2
-2 = falling edge of probe 2
If the measuring operation is performed with two measuring systems, a maximum of two
trigger events per probe can be programmed (rising or falling edge). The measured values of
both probes are acquired for each of the two trigger events. The default PROFIBUS telegram
391 setting means one measured value per trigger event and position controller cycle is
possible.
For MEAC, the number of measured values per trigger event can be increased with
PROFIBUS telegram 395 to eight measured values for rising edge and eight measured
values for falling edge of each measuring input and position control cycle. This allows higher
feed rates or speeds to be implemented compared with PROFIBUS telegram 391.
For further information concerning the telegram selection, see Section "Telegram selection
(Page 449)".

0 = abort measurement job (e.g. for synchronized actions)
1 = up to four different trigger events that can be activated at the same time.
2 = up to four trigger events can be activated in succession.
Error output if the first trigger event is already present
3 = up to four trigger events can be activated in succession.
NO error output if the first trigger event is already present
0/not set = use active measuring system
1 = first measuring system
2 = second measuring system (if available, otherwise the first measuring system is used.
No error message is output).
3 = first and second measuring system
Note
If the measuring job is performed with two measuring systems, a maximum of two trigger
events can be programmed. The measured values of both measuring systems are
acquired for each of the two trigger events.
Mode 3 is not supported by MEAC.
