viva 1.1 (for process analysis)
Poll
The character string (optional) defined in Command is sent to the
instrument and an answer is expected and evaluated within the Time-
out defined in the instrument settings. This action continues to be
repeated until a character string received corresponds to the regular
expression in the Comparison. If this does not take place within the
Timeout defined in the command, the command will be canceled.
Command
Character string that is to be sent to the instrument. Details are to be
found in the technical documentation of the instrument in question.
Entry 250 characters
NOTE
All ASCII characters can be entered with their two-digit hex code after
backslash (e.g. \1B = Escape).
Variable
Selection of an available sample data variable under which the received
data is to be saved for the actions Read, Wait for and Poll. Sample data
variables that are not permitted to be assigned to one of the specified
sample data variables must be defined for this purpose in the START
command (see Chapter 5.5.2.9.2.5, page 581).
Selection Sample data variables
NOTE
Several indexed variables (e.g. Input1, Input2, etc.) can also be cre-
ated in order to be able to store the substrings requested with regular
expressions directly in various variables.
Example
Variable = SD.Input1
Comparison = (\d+\.\d+),(\d+\.\d+)
Two measured values (separated by a comma) are filtered out of a ran-
dom receiving line and saved in the two variables SD.Input1 and
SD.Input2.
