Supported data types
In PLCSIM Advanced V2.0, the Runtime API supports the data types of the S7-1500 CPUs.

types.
The data types Counter, Date and Time must be transferred to the API BDC-coded so that
the values are written to the counter and no incorrect values are returned when reading.
For these data types, you must perform a BCD conversion before writing and a BCD back-
conversion after reading.
Example:
If the value 999 is transferred to the API as 2457
999. Without BCD conversion, there is no
