Good day, Friends! In front of me, as a beginner programmer, self-taught, has the task which is subdivided into subtasks:

1. To connect two scanner cognex Dataman 262х with the controller S7-1200 (6ES7212-1HE40-0XB0).
2. To obtain data from both scanners into a PLC table.
3. Code Received from the 1st of the scanner must correspond to the ID of the 2nd scanner after a certain number of pulses of the encoder.
4. Immediately after receiving the bundle of two codes, upload them to a SQL database. Can anyone help, prompt or to throw an example? Not a trivial task.

Hello Ruzhanin;

The first part of the task, connecting the Datamon scanners to a S7-1200 over Profinet, I can help you with: look at the following links.

For the second part, synchronizing the encoder and collecting your data in a database, you will have to be more explicit in your description, I am not sure what exactly you need to do.

The folowing thread may help you for the SQL database connection:

Hope this helps,
