Are you planning to upgrade your automation panel but confused between the Siemens CPU 1214C and CPU 1215C? You are not alone. These two are the most popular PLCs in the SIMATIC S7-1200 family.

At JRM Solutions Noida, we often get asked by panel builders: “Is it worth paying extra for the 1215C, or should I stick with the 1214C?”

In this technical guide, we break down the key differences to help you decide.

1. The Main Difference: Ethernet Ports & Analog Outputs

The biggest difference lies in connectivity and drive control.

• Siemens CPU 1214C: Comes with 1 PROFINET Port. If you want to connect an HMI and a Laptop simultaneously, you will need an external Ethernet Switch.

• Siemens CPU 1215C: Comes with 2 PROFINET Ports (Built-in Switch). You can create a line topology (daisy chain) without buying an extra switch.

Crucial Upgrade: The CPU 1215C also includes 2 Analog Outputs (0-20mA) built-in. The 1214C has Zero Analog Outputs.

2. Technical Comparison Table

Here is a quick snapshot of the specifications:

3. When to choose the CPU 1214C?

The CPU 1214C is the industry standard for compact machines.

• Choose this if you do not need to control VFD speed via Analog (0-10V/4-20mA).

• Ideal for Packaging machines, Conveyors, and Pump control where cost is a priority.

We have full stock of 1214C DC/DC/DC and Relay models at trade prices.

4. When to upgrade to CPU 1215C?

The CPU 1215C is a powerhouse.

• Choose this if you need to control VFD Speed or Proportional Valves directly (using the 2 Analog Outputs).

• If you want to save space and money by removing an external Ethernet Switch.

• It offers slightly more memory (125 KB) for complex logic.

Conclusion

If you want a cost-effective solution, go for the 1214C. But if you need Analog Outputs and Dual Ports, the 1215C is the clear winner.
