Siemens 6ES7518-4UP00-0AB0 CPU 1518TF-4 PN/DP

Siemens specifies CPU 1518TF-4 PN/DP with 9 MB program and 60 MB data work memory, PROFINET IRT with a 2-port switch, PROFINET RT, PROFINET basic services and PROFIBUS. It has 1 ns bit performance and requires a SIMATIC Memory Card. Unlike CPU 1518T-4 PN/DP, this is an F-CPU as well as a Technology CPU. Its Technology Objects, motion configuration, F-program, PROFIsafe communication and safety validation must all be treated as project-critical data.

The Siemens data record lists FS11, firmware V3.1 and TIA Portal V19 for FW V3.1 or V17 for FW V2.9 and later. The official record lists PROFIsafe V2.4/V2.6 and Technology CPU motion functions; it does not make an unconfigured CPU a safe replacement. Before service, retain the Memory Card, program and F-program backup, safety signature, PROFIsafe addresses, F-I/O list, safety project, Technology Objects, drive and encoder configuration, firmware and all network parameters. Revalidate the safety application using the documented site procedure before operation. Do not treat the non-failsafe CPU 1518T-4 PN/DP as a direct replacement, even where work memory and communications look similar.

Safety-oriented motion-control systems that require both Technology CPU functions and documented PROFIsafe engineering.

This page is specific to Siemens 6ES7518-4UP00-0AB0 as a CPU 1518TF-4 PN/DP. A similar Siemens component should not be treated as a direct replacement until the complete order number, hardware revision, terminal block or BaseUnit, signal configuration and system application have been confirmed. Compare the order code character by character with the installed item, then check the ET 200SP HA station records, module position, field wiring and applicable engineering documentation. For Ex components, hazardous-area certification, the Ex module-group arrangement and the permitted field-device connection must also be confirmed. The original label and project records remain the basis for technical comparison.

Please provide the complete CPU label, FS11 or installed revision, firmware, TIA Portal and STEP 7 Safety versions, SIMATIC Memory Card, project and F-program backups, safety signature, PROFIsafe addresses, F-I/O list, Technology Objects, axis and drive configuration, and quantity.
