Siemens 6ES7518-4FX00-1AC0 SIMATIC S7-1500F CPU 1518F-4 PN/DP MFP Bundle C/C++ OPC UA Runtime PLC

The Siemens 6ES7518-4FX00-1AC0 is a SIMATIC S7-1500F CPU 1518F-4 PN/DP MFP bundle: a fail-safe CPU with 9 MB of program memory and 60 MB of data memory, sold together with C/C++ Runtime and OPC UA Runtime licenses already included. It has four interfaces (PROFINET IRT, PROFINET RT, PROFINET basic services, PROFIBUS) and needs a SIMATIC Memory Card of at least 2 GB.

Selection Notes

The MFP suffix and bundled licenses are the reason to choose this order number over the base CPU 1518F-4 PN/DP MFP (6ES7518-4FX00-1AB0): C/C++ Runtime and OPC UA Runtime are already licensed, so custom C/C++ function blocks (via ODK/Target 1500S) and a native OPC UA server run without ordering separate runtime licenses. The fail-safe F rating still applies, so the CPU handles standard and safety logic together. Projects that only need standard fail-safe control without C/C++ blocks or OPC UA can use the plain CPU 1518F-4 PN/DP instead and skip the added runtime memory this bundle reserves.

Applications

Machines needing custom compiled algorithms alongside standard PLC logic and a built-in OPC UA server for MES or SCADA connectivity, on lines that also require fail-safe shutdown from the same controller.
