What does TPS means?

Hello all.
Phoenix is offering for instance AXL F BK PN TPS - Bus coupler. What does the abbreviation TPS stands for and what feature(s) does it indicate?
I have read the product documentation but it is not described there. Also a quick search on the web did not gave any clues.
Thanks you for your feedback

The AXL F BK PN TPS is suitable to an ASR Redundancy system using AXC F 2152 or AXC F 3152. This module is able to provide profinet data to both PLC, primary and secondary one.

                                            I hope this information helps in any way. try looking the controller manual or ASR redundacy system manual.  
                                              
                                            Best Regards,  
                                            Jeferson Carvalho.

Unfortunately this question is not related to PLCnext Technology, but I have checked with my colleagues who are responsible for this product.
The letters “TPS” refer to the type of Profinet chip used in that version of the bus coupler (BK). The letters do not indicate any functionality implemented by the BK. To find out more about the functionality of this BK, and how it might be different to other versions of the product, please get in touch with the technical specialists in your local Phoenix Contact office.
