Send Get {tagname|service.tagname|service} to get the value of a tag within the global
data service. To get the value of a tag within another service, prefix the tagname with the
service name. For example, a GET <service.tagname> command such as GET
eip.input for the EIP input assembly.
The AVP service allows retrieval of step and datum information from the job tree using
forward slash ‘/’ in the symbolic name path. GET avp/insp1/snapshot1/status paths are
not case-sensitive and do not need to be fully qualified if unique.
GET avp/snapshot1/status will return the same result if there is only one inspection.
When issued against a step, GET avp/snapshot1 will return the values for all datums.
Success Return: On success will return the value stored in the tag.
For example:
ABCD
Fail Return: On failure will return !ERROR followed by the reason for the failure.
For example:
!ERROR Tag matchstring66 not found
GETIMAGE <-transfer=ymodem> [-format={jpg|png}] [-quality={0-100}]
[-woi=left,top,right,bottom] [-inspection=n]
Initiates serial transfer of inspection image (RS-232 only).
Note: This command always returns the last (most recent) image.

from the first snapshot within that inspection. If not specified, the image will be from the
first inspection that does contain a snapshot.
The following example will retrieve an image from the camera with these settings: Protocol:
ymodem; Format: png; Quality: N/A; Inspection: second inspection.
GETIMAGE –transfer=ymodem –format=png –inspection=2
