Frequently Asked Questions (FAQ)

• What is the main advantage of this CPU over the 1212C model? The 1214C offers significantly more integrated I/O (24 points vs 14 points) and supports twice as many expansion modules. This makes it suitable for larger, more complex applications.
• Can I connect this to an existing PROFIBUS network? Yes, but you need an additional communication module (CM 1243-5). The built-in port only supports PROFINET Ethernet communication.
• How should I protect the relay outputs when switching inductive loads? Always use surge suppressors (snubbers or varistors) across inductive loads like solenoid valves or contactor coils to protect the relay contacts from arcing.
• What is the maximum cable length for the digital inputs? You can use up to 500 meters with shielded cable or 300 meters with unshielded cable. For high-speed counting functions, reduce this to 50 meters with shielded cable.
• Is the 4MB load memory sufficient for data logging applications? The 4MB integrated memory provides ample space for most data logging needs. For extensive historical data, consider using a SIMATIC memory card for additional storage capacity.
