Siemens 6ES7518-4FP00-0AB0 CPU 1518F-4 PN/DP

Siemens specifies CPU 1518F-4 PN/DP with a PROFINET IRT interface and 2-port switch, a second PROFINET RT interface, a third PROFINET basic-services interface and an integrated PROFIBUS interface. It has 1 ns bit performance and requires a SIMATIC Memory Card. Its F-CPU role is the key distinction: safe control depends on a documented safety application and configured PROFIsafe communication, not merely on matching the order number or physical interfaces.

The reviewed Siemens data sheet lists FS11 and firmware V3.1, configured from TIA Portal V19 for FW V3.1 or from V13 for FW V1.5 and later. Any repair or replacement must preserve and validate the F-program, safety signature, F-CPU parameters, PROFIsafe addresses, F-I/O configuration, firmware and hardware functional status. Confirm the safety project using the applicable Siemens documentation and the site validation procedure before return to service. This CPU is not a direct replacement for CPU 1518-4 PN/DP: a standard CPU does not provide the same safety-oriented function. A similar Siemens product should not be treated as a direct replacement until the complete order number, hardware revision, firmware, electrical configuration, software license and system application have been confirmed.

This page is specific to Siemens 6ES7518-4FP00-0AB0 as a CPU 1518F-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, F-program backup, safety signature, PROFIsafe addresses, F-I/O list, PROFINET and PROFIBUS configuration, and quantity.
