Capability to set additional permit
conditions for ADC data recording in
buffer memory
E20-10:
- "according to differential" signal in
ADC selected channel,
- blockage of set number of frames
transmission from the beginning of data
acquisition (p.
5.2.2
)
no yes
Mode of hardware acquisition stopping
according set number of collected data
frames (p.
5.2.2
)
On stop the data acquisition restart can
be started, for example, per external
sync-signal START. In practice this
capability allows to implement start-
stop operation for several data
acquisition start modes
no yes

mandatory computer-
sourced restart is required restart is not required, because of the
required minimum number of data
frames will be automatically
(hardware logic) deleted from buffer
memory of
E20-10 to eliminate
overflow, and program-accessible
overflow indicator is activated.
