Good day I have to retrieve data from a Siemens S7-300 with an Axc F 2152. Can the ComSiemens library be used on the older S7-300 or is it only compatible with the newer 1200/1500 controllers? What would be the best way to interface with an S7-300? Thanks
Hello, This table, from the documentation for that library, shows that the library supports 300, 400, 1200 and 1500 series PLCs: 
If there are any questions that are not answered by the documentation, you can get support using the “contact” button on the product page in the PLCnext Store:

Thank you Martin, I did not notice the 3xx in the table. This does answer my question.
