Standard Mode
Data sets can only be stored in the operating device if their structure is
still identical to the data set structure specified for the corresponding
recipe in the application description. This can be checked by the oper-
ating device on the basis of a version number (see Structure of Data
Set File). If a data set which is found to be invalid is received, it is
rejected and a system message to this effect is output. The receive
process is not terminated, however.
If a data set with the same number as the transferred data set is
already stored in the Flash Eprom, the newly received data set is
rejected without any warning to the operator.
If a data set with the same number as the transferred data set is
already stored in the RAM, a parameter setting in the received data
(see Structure of Data Set File) determines whether or not the existing
data set is overwritten. If it is not supposed to be overwritten, and
another data set with the same number already exists in the operating
device, the newly received data set is similarly rejected without any
warning to the operator.
5.23.3.6 Structure of a Data Set File
The data sets transferred to the PC are generally stored in a file.
If this file is only used for backup purposes, the operator does not nec-
essarily be familiar with its structure. In this case, the file can merely be
transferred back to the operating device unchanged when it is needed.
If the data are to be processed further, for example, within the scope of
production data acquisition, the user should understand the structure of
the file.
All of the data in the data set file are represented by a simple language
specifically developed for this purpose.
The following are elements of this language:
Key words: S + two further letters. They normally appear at the beginning of a line.
Example: SDW or SFA
Decimal number: Any number of the digits 0-9, preceded by a negative sign when
required. Example: 999 or -1234567
Hexadecimal number: H + any number of the digits 0-9 or letters A-F or a-f. Example: H999 or
H123abCD4
Hexadecimal string: C + any even number of the digits 0-9 or letters A-F or a-f.
Example: C12 or CAAFF33
ASCII string: Any string of characters enclosed between two backslash characters
(\) .
