Lifecycle & Replacement

Product lifecycle (PLM): PM300 – Active product

Phase‑out started: 1 October 2019 (official Siemens PLM effective date)

Recommended replacement: SIPLUS S7‑1500 CPUs or SIMATIC S7‑1200 (depending on performance). Replacement is not a drop‑in; consider:

  • Different form factor (S7‑300 vs S7‑1500)
  • Memory capacity and I/O addressing
  • PROFINET / PROFIBUS configuration
  • Software migration (TIA Portal vs STEP 7)

Alternate order number (SIPLUS extreme): 6AG1315‑2EH14‑7AB0 (similar, different temperature range / coating).

Frequently Asked Questions

Q1: What is the work memory size of the 6AG1315‑2EH14‑2AY0?
384 KB integrated work memory.
Q2: Is a Micro Memory Card mandatory?
Yes. A SIMATIC Micro Memory Card (MMC) is required for operation; it replaces the internal load memory.
Q3: Which communication interfaces are available?
MPI/DP (up to 12 Mbps) and PROFINET with integrated 2‑port switch (RJ45).
Q4: What is the ambient temperature range for this SIPLUS CPU?
–25 … +60 °C, with condensation and aggressive atmosphere allowed (conformal coating).
Q5: When was this product discontinued, and what is the replacement?
Phase‑out began 1 October 2019. For new designs, consider SIPLUS S7‑1200 or S7‑1500 variants; replacement requires engineering adaptation.
