CPU 1516pro F-2 PN — key specs and fit
The 6ES7516-2GP03-0AB0: This central processing unit sits in the ET 200pro distributed I/O system, carrying 3 MB for program and 7.5 MB for data. The first PROFINET interface includes a 3-port switch with IRT for isochronous real-time; the second interface runs PROFINET RT. Enclosure is IP65/67, so it mounts directly in the field alongside sensors and actuators without a cabinet. A SIMATIC Memory Card and a connection module are required to run it — both separate order items.
