2D channel API reference¶
A 2D represents an experimental channel which acquisition result is a image value.
A 2D has a
state, and a
value attributes. The state indicates at any
time if the 2D is stopped, in alarm or moving. The value, indicates the
current 2D value.
The other attributes are:
- data source
Unique identifier for the 2D data (value attribute)
name of the timer channel (proceeding from the same controller) to be used when the channel is acquired independently
__default - controller’s default timer
__self - the same channel acts like a timer
None - independent acquisition is disabled
- integration time
integration time (in seconds) to be used when the channel is acquired independently
The available operations are:
- start acquisition
starts to acquire the 2Ds
stops the 2D acquisition in an orderly fashion
stops the 2D acquisition as fast as possible
Release hung acquisition e.g. due to the hardware controller that got hung. You should first try stop/abort.
