• Integrated 768 KB work memory (384 KB code / 384 KB data).
• Three interfaces: MPI/DP (12 Mbps), PROFIBUS-DP (master/slave), and IF for IFM.
• Supports CiR (Configuration in RUN) – basic load 100 ms + 120 µs per I/O byte.
• Typ. processing: 0.1 µs for bit/word/fixed-point, 0.6 µs for floating-point.

 Oiltech Controls Review

• A robust workhorse for medium-to-large S7-400 applications.
• Dual PROFIBUS ports allow flexible distributed I/O and master-slave setups.
• 768 KB memory handles complex logic, motion, and process control.
• Isochronous mode supports high-speed synchronized motion (5 ms cycle).
• We recommend this CPU for upgrading existing 414-2 or expanding I/O capacity.

 FAQ – Expert Q&A

• Q: Can I use this CPU as a DP slave on the second interface?
  A: Yes. Both MPI/DP and the second DP interface can operate as master or slave. The third IF (pluggable) also supports DP.
• Q: What is the maximum number of DP slaves on interface 2?
  A: Up to 96 slaves with 6 KB address area each. For interface 1 (MPI/DP), max. 32 slaves with 2 KB area.
• Q: How does CiR (Configuration in RUN) work?
  A: CiR allows adding or removing I/O modules without CPU stop. Basic load 100 ms + 120 µs per I/O byte – plan for this time.
• Q: Is the 768 KB memory enough for large applications?
  A: For most mid-size plants, yes. For large SCADA or motion, consider 414-4 or 416. The 384/384 split is fixed.
• Q: What battery type is required for retentive memory?
  A: Standard lithium backup battery (e.g., 6ES7971-0BA00). Typ. backup current 40 µA – battery life approx. 1–2 years.
