Product description

Siemens 6ES7 516-3FN01-0AB0 is a fail-safe CPU 1516F-3 PN/DP central processing unit from the SIMATIC S7-1500F range. Siemens documents 1.5 MB of work memory for the user program and 5 MB for data. Bit performance is 10 ns. The first communication interface supports PROFINET IRT through a 2-port switch. Further interfaces are PROFINET RT and PROFIBUS DP. The supply voltage is 24 V DC. A SIMATIC Memory Card is required for operation and program storage. The F-CPU combines standard and safety programs in one central processing unit. The full MLFB, hardware and firmware version, project version, F-signature, safety parameters and network topology are separate identification and configuration fields. Memory capacity, F-function and interface configuration describe the documented CPU variant within the product range. The Siemens data sheet lists overall dimensions of 70 × 147 × 129 mm in width × height × depth order. Its weight is stated as ca. 845 g. These mechanical values are relevant to installation space, mounting, handling, storage and transport. Additional room for connectors, wiring and maintenance access depends on the specific cabinet arrangement. The overall dimensions describe the CPU enclosure itself rather than any additional installation clearance. Mounting position, cable routing and adjacent modules remain separate conditions of the installed system. The complete designation 6ES7 516-3FN01-0AB0 identifies the documented CPU-1516F-3-PN/DP version. Project file, device versions, communication parameters and approved safety data belong to the configuration records of the installed system. Those records remain distinct from the mechanical and electrical product data listed here.
