Configuration
4.18 Data points
Before importing the data points, make sure that the respective stations have been created
with CPUs of the same name, modules of the same name and PLC tags of the same name.
When you import the corresponding stations of the project are searched for based on the
module names in the CSV files. If a target station does not exist in the project or the module
has a different name, the import of the particular CSV file will be ignored.
Restrictions for the import of data points
In the following situations the import of data points will be aborted:
● An attribute required by the module is missing in the CSV file to be imported.
Example: If a data point to be imported uses a time trigger, the import will be aborted if no
time-of-day synchronization was configured for the module.
● The telecontrol protocol used by the module differs from that of the original module.
Only when importing into several modules:
● The import is aborted when a module or CPU name is different from the data in the CSV
file.
Note:
Modules with the same telecontrol protocol are compatible with each other:
● TeleControl Basic
All SIMATIC NET modules with the TeleControl Basic protocol:
CP 1243-1, CP 1242-7 GPRS V2, CP 1243-7 LTE, CP 1542SP-1 IRC
● ST7
CP 1243-8 IRC, CP 1542SP-1 IRC, ST7 TIM
● DNP3
CP 1243-1, CP 1243-8 IRC, TIM modules capable of DNP3
● IEC
CP 1243-1, CP 1243-8 IRC
Data points can be imported and exported between compatible modules.
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.
