Hi, You may find this link useful for WinCC Archiving capabilities/licensing of PCS7 without a separate Process Historian (PH). TLDR; you get 512 archiving tags included with the OS server. https://support.industry.siemens.com/cs/ww/en/view/108893968 Additionally you may want/need to add a PH if you need very long term storage of the data or for other reasons. There is a pretty substantial investment for a PH. For your case of +/- 100 archive tags, I think it is more reasonable to just stick with OS Archiving to start. You can always add an Information Server later if you need to run advanced reports with or without the PH. |

There is a calculation based on frequency of data collection which I don't have a link for right now, but should be in the built in help or WinCC manual. The calculation will help you set up the time period of all segments and the max size of all segments. These would be the active segments you can immediately query without having to do anything. Then you can have backup running to copy segments to long term storage location (different folder/drive/network etc based on your risk level) which can be loaded manually if you need to look at data from that time period once they aren't active. In practice you can save data for a very long time, there are some guidelines for how many archive segments you should have loaded at any one point in time. About 2GB and 200 segments as of PCS7 9.0. An example setting might be 1 segment = 1 week (assuming your data calculation is OK), so you could have ~4 years worth of segments active at a time, with the option to load backed up segments if you need to look back further than that. |

Hi, There is some calculation earlier and in addition to that now they have the system requirement for PH. Refer below manual in the link (page 10 to 12) and in case you want to use get the suggestion from local supplier. https://support.industry.siemens.com/cs/ww/en/view/109748863 Thanks |
