Frequently asked questions
What compliance documentation exists for this CPU?
RoHS compliance is stated from 24-01-25. REACH candidate list information is available from Siemens. The part carries export control classification AL: N / ECCN: EAR99H.
What are the key memory and interface specifications?
18 MB work memory for program, 150 MB for data. Five PROFINET interfaces: two with integrated 2-port switch for PROFINET RT, one additional PROFINET port, and two H-SYNC ports for redundant coupling.
CPU for redundant safety control
The Siemens 6ES7518-4JT10-0AB0 CPU 1518HF-4 PN sits in the S7-1500H line, built for high-availability and fail-safe applications. It carries 18 MB work memory for program and 150 MB for data, with five PROFINET ports: two interfaces each with a 2-port switch and one additional PROFINET port, plus two H-SYNC links for synchronous redundant operation. Requires a SIMATIC Memory Card.
Integration notes
The H-SYNC interfaces are dedicated to the synchronization fiber between two CPUs in a redundant pair; they are not available for IO communication. First and second PROFINET interfaces each have an integrated 2-port switch for line or ring topology. The third PROFINET interface is a single port for additional IO or HMI connection. Packaged as a single piece, dimensions 25.6 x 20.6 x 17.5 cm. Verify available DIN-rail space and clearance for front-panel cabling before installation.
RoHS compliant since 24-01-25. REACH candidate list information is available — confirm with your compliance team if article-level declaration is required. Part is classified under group code R132 and product group 4B91 for logistics.
