Assignment repair
If you have named the PLC tags in a station into which you want to import differently from
the station from which the CSV file was exported, the assignment between data point and
PLC tag is lost when you import.
You then have the option to either rename the existing PLC tags appropriately or add
missing PLC tags. You can then repair the assignment between unassigned data points and
PLC tags. This function is available either via the shortcut menu of the module (see above)
or with the following icon to the upper left in the data point editor:
If a PLC tag with a matching name is found for a data point by the repair function, the
assignment is restored. However the data type of the tag is not checked.
After the assignment repair make sure that you check whether the newly assigned PLC tags
are correct.
4.10.2 Syntax of the data point names
Character set for data point names
When you create a data point, a preset name "DataPoint_n" is adopted. In the data point
table and in the "General" tab of the data point you can change the name of the data point.
When assigning names only ASCII characters from the band 0x20 ... 0x7e (no. 32-126) may
be used with the exceptions listed below.
Forbidden characters:
● . ' [ ] / \ |
period, apostrophe, square brackets, slash, back slash, vertical line (pipe)
