Why Engineers Specify This Model
- Dual PROFIBUS DP ports – acts simultaneously as DP master on two independent networks, enabling distributed I/O and drive integration without additional CP modules
- Compact integrated I/O – eliminates the need for separate SM modules in small-to-mid-scale applications, reducing panel space and BOM cost
- 192 KB work memory – sufficient for complex ladder/FBD/SCL programs including PID loops, motion sequences, and data logging
- Proven S7-300 ecosystem – fully compatible with STEP 7 v5.x and TIA Portal (via legacy mode), with extensive library support
- Hot-swap MMC – program backup and firmware update without PC connection, critical for field service scenarios
- Long product lifecycle – Siemens extended support availability; widely stocked as a spare for existing installed base

Application-Specific FAQ
Q: Can the 6ES7313-6CF03-0AB0 replace a 6ES7313-6CE01-0AB0?
A: Yes, the -6CF03 is the successor to the -6CE01 with identical pinout and expanded work memory (192 KB vs 128 KB). Programs are fully compatible after recompilation in STEP 7.
Q: Does this CPU support PROFINET?
A: No. The 313C-2 DP supports PROFIBUS DP only. For PROFINET connectivity, consider the 6ES7315-2EH14-0AB0 (CPU 315-2 PN/DP) or add a CP 343-1 communication processor.
Q: What programming software is required?
A: SIMATIC STEP 7 v5.5 SP4 or higher (classic), or TIA Portal V13 SP2+ with the S7-300 legacy option pack. IEC 61131-3 languages supported: LAD, FBD, STL, SCL, GRAPH.
Q: Is an MMC (Micro Memory Card) required for operation?
A: Yes. The CPU requires an MMC to retain the program after power loss. The 6ES7953-8LJ31-0AA0 (4 MB) is the recommended card for this CPU.
Q: Can this unit be used in a redundant (H-system) configuration?
A: No. Redundant S7-300 H-systems require the CPU 317H or CPU 319-3 PN/DP. The 313C-2 DP is a standard (non-redundant) CPU.
