Yeah, this is pretty much garbage from Siemens.
I have a presentation showing a 1214C (my same version) running SCL, but my TIA v11 SP2 doesn't support it yet.
How quaint.
This is probably only about the second most-frustrating thing about this series of products, right next to v1 of the S7-1200 firmware wiping all retentive registers on power cycle (how'd that make it past testing, lol?).
