That IP rating means the CPU runs without an enclosure in wet or dusty environments — it is rated for direct mounting on machine frames or conveyors where a standard IP20 controller would need a cabinet. ## Integration notes The CPU requires a separate SIMATIC Memory Card (not included) to load the firmware and application, and a matching connection module for the ET 200pro base unit. The two PROFINET ports allow a line topology without an external switch; the IRT interface supports isochronous motion control cycles down to 6 ns bit performance.","metaTitle":"Siemens 6ES7516-2PP03-0AB0 CPU 1516pro-2 PN, 2 MB/7.5 MB","metaDescription":"Active Siemens CPU for ET 200pro, PROFINET IRT/RT, IP65/67, 2 MB program / 7.5 MB data memory.
