Siemens 6ES7518-4TP00-0AB0 CPU 1518T-4 PN/DP

Siemens identifies this model as CPU 1518T-4 PN/DP. It combines PROFINET IRT with a 2-port switch, PROFINET RT, PROFINET basic services and PROFIBUS, with 1 ns bit performance and a required SIMATIC Memory Card. The T designation matters: this is a Technology CPU for configured Motion Control and Technology Objects. It is neither an F-CPU nor a substitute for CPU 1518TF-4 PN/DP where a documented safety application is required.

The reviewed Siemens equipment manual lists FS11 and firmware V3.1, with TIA Portal V19 for FW V3.1 or V17 for FW V2.9 and later. Preserve the CPU project, Memory Card, firmware, drive configuration, Technology Objects, motion parameters, encoder assignments, axis configuration and network topology before service. Siemens records PM400 phase-out announcement status, effective 2025-10-01, in the Industry Mall record checked on 2026-07-24; this is not an availability statement. Confirm the exact Motion Control function set and any optional technology licenses from the installed project and current Siemens documentation. 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 6ES7518-4TP00-0AB0 as a CPU 1518T-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 version, SIMATIC Memory Card, project backup, Technology Objects, axis and encoder configuration, drive list, PROFINET and PROFIBUS topology, and quantity.
