Experience-based Selection Guide
- Choose CPU 313C when you need a compact controller with mixed I/O and moderate processing power.
- Ideal for applications requiring up to 24 digital inputs and 16 digital outputs plus analog signals.
- If you need more memory or faster counters, consider the CPU 314C-2 DP or higher.
- For pure digital applications without analog needs, the CPU 312C is a cost-effective alternative.
- Ensure you have a STEP 7 V5.1 SP2 or later for configuration.
