How to Select a Siemens SIMATIC S7-1200 PLC
Choosing an S7-1200 PLC should start with the requirements of the machine rather than simply selecting the highest or lowest CPU model.
1. Determine the number of I/O points
Calculate the required digital and analog inputs and outputs.
2. Check the electrical configuration
For example, a CPU may be available in DC/DC/DC, AC/DC/Relay or DC/DC/Relay configurations.
3. Check communication requirements
Determine whether the PLC needs to communicate with HMIs, drives, remote I/O, SCADA systems or other controllers.
4. Consider expansion
If additional I/O or communication modules may be needed later, select a CPU and system architecture that can accommodate the planned expansion.
5. Check the existing Siemens article number
For replacement applications, don’t rely only on the description “S7-1200 CPU 1214C.”
The complete article number is important.
For example:
6ES7214-1HG40-0XB0
identifies a specific CPU 1214C variant.
