Datapoint Types - Siemens S7-1200 TELECONTROL Operating Instructions Manual

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.
