Poll
The character string defined in Command (optional) will be sent to the
device; an answer is expected from the device and evaluated within
the Timeout defined for the device settings. This action will be repea-
ted until the answer of the device is identical to the regular expression
in Comparison. If this answer is not received within the Max. wait-
ing time defined in the command, then the command is canceled.
Command
Character string to be sent to the device. Details can be obtained from the
documentation for the respective device.
Input 250 characters
Note
All ASCII characters can be entered with its two-digit hex code after
backslash (e.g. \1B = Escape).
Variable
Selection of an available method variable under which the received data
for the Actions Read, Wait for and Scan will be saved. Method varia-
bles must be defined in the START command for this purpose which are
not permitted to be assigned to any system variables.
Selection Method variables
Note
It is also possible to create several indexed variables (e.g. Input1,
Input2, …) in order to save the character substrings produced by regu-
lar expressions directly in the different variables.
Example
Variable = MV.Input1
Comparison = (\d+\.\d+),(\d+\.\d+)
Two measured values separated by a semicolon are filtered out of a
random, received character string and saved in the two variables
MV.Input1 and MV.Input2.
Comparison
Entry of a character string which should be compared to the data received
by one of the Actions Read, Wait for and Scan. In this field so-called
