I apologize for the confusion, but it seems like you have provided a product code for a Siemens module or accessory rather than a complete PLC (Programmable Logic Controller) model number. 

The model number you provided, 6ES7952-1KK00-0AA0, corresponds to a Siemens memory card module. It is part of the SIMATIC S7-300 series and is used to expand the memory capacity of the PLC. This module allows you to store and transfer program and data files between different PLCs.

If you have any specific questions about the 6ES7952-1KK00-0AA0 memory card module or require information about a specific Siemens PLC model, please let me know and I'll be happy to assist you further.
