Syntax Of The Data Point Names; Datapoint Types - Siemens SIMATIC NET TeleControl S7-1200 CP 1243-1 Operating Instructions Manual

● An attribute required by the CP 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 CP.
Only when importing into several CPs:
● The import is aborted when a CP or CPU name is different from the data in the CSV file.
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 CP (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.

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 may be used with
the exceptions listed below.
The following characters are forbidden since they do not adhere to the syntax rules of TCSB
for OPC items:
Non-permitted characters: . ' [ ] / \ |
period, apostrophe, square brackets, slash, back slash, vertical line (pipe)

Datapoint types

During the configuration of the user data to be transferred by the CP, each data point is
assigned a protocol-specific data point type. The data point types supported by the CP along
with the compatible S7 data types are listed below. They are grouped according to format
(memory requirements).
As of the firmware version named in the preface along with STEP 7Basic V14, the CP
supports the following data point types and data types.
