Frequently Asked Questions
Q: What is the main difference between CPU 312 and higher models like CPU 314?
A: The CPU 312 is an entry-level model with smaller memory and processing speed, suitable for simpler applications. Higher models offer more memory, faster execution, and support for more complex functions and larger I/O counts.
Q: Can I use this CPU as a PROFIBUS-DP slave?
A: Yes, the integrated interface can be configured as a DP slave, allowing this CPU to be part of a larger automation system controlled by a master CPU (e.g., an S7-400).
Q: Does it have a built-in real-time clock?
A: No, the CPU 312 does not have a hardware clock. Time-of-day functions require synchronization from a master via the PROFIBUS network or a separate clock module.
Q: How many modules can I connect to this CPU?
A> You can expand with up to 8 modules (SMs, CPs, FMs) on a single rack. The total configuration must stay within the CPU's address and power supply limits.
Q: What memory card does it use?
A> The CPU 312 uses a Micro Memory Card (MMC) for storing the user program, configuration, and data blocks. This card is required for operation.
