6ES7315-2AF03-0AB0 Siemens SIMATIC S7-300 CPU 315-2 DP Standard CPU 128 KB Integrated PROFIBUS DP Master/Slave Interface

Product Overview: Siemens 6ES7315-2AF03-0AB0

Parameter Specification
Brand Siemens
Order Number 6ES7315-2AF03-0AB0 (successor to 6ES7315-2AF02-0AB0)
Product Name CPU 315-2 DP – Standard CPU
Product Family SIMATIC S7-300 modular controller system

Application & Fault Scenarios

Typical Uses: A mid-range S7-300 CPU where distributed I/O or drive integration is needed without adding a communication processor. Common in packaging machines, conveyor systems, pump skids and existing production lines where ET 200M racks and SINAMICS/G120 drives hang off the DP bus. Also the standard like-for-like swap when a failed CPU 315-2 DP must be replaced quickly.
Common Field Issues:
  • CPU won't leave STOP / "no MMC" fault → insert a correctly programmed MMC; a blank or incompatible card keeps the CPU in STOP. Check card capacity and whether it was written by a compatible STEP 7 version.
  • SF/BF LED red after replacement → station address or baud rate mismatch on the DP bus; re-download hardware config, check terminating resistor and SUB-D plug seating.
  • MPI/PG can't connect → the combined port may be set to DP-only mode or the PG access path is wrong; set the correct MPI address/baud in the PG/PC interface settings and use the right cable (PC Adapter USB/MPI).
  • Random STOPs or diagnostic entries → check 24 V supply stability, backplane bus current budget (too many SMs), module slot numbering vs. HW config, and environmental factors (heat, dust).

FAQ

Q1: What is 6ES7315-2AF03-0AB0?
A: It is the SIMATIC S7-300 CPU 315-2 DP standard CPU with 128 KB working memory, a combined MPI/PROFIBUS DP interface (master and slave capable), DC 24 V supply and sub-microsecond bit performance.
Q2: Does it need a memory card?
A: Yes — an MMC (Micro Memory Card) is mandatory; the CPU will not start without one. Order separately, e.g. 6ES7953-8LM31-0AA0. Note this is an MMC, not the S7-1500 SIMATIC Memory Card.
Q3: Can it replace 6ES7315-2AF02-0AB0 or 6ES7315-2AG10-0AB0?
A: -AF03 supersedes -AF02 directly (same 128 KB class). The -AG10 (CPU 315-2 PN/DP) adds a PROFINET port and has different memory — not a drop-in replacement; check your program and hardware config carefully.
