With multiple CPU variants available in the SIMATIC S7 1200 G2 lineup, selecting the right model for your specific application requires careful consideration of I/O requirements, memory needs, communication protocols, and budget. This buying guide will help you navigate the options and make an informed decision.
Don't miss, SIMATIC S7 1200 G2: The Next-Generation PLC Redefining Industrial Automation
Step 1: Define Your I/O Requirements
The S7 1200 G2 family offers CPU variants with different onboard digital and analog I/O counts. Start by listing all inputs and outputs your machine requires, then identify whether you need expansion modules. Remember that signal boards can be inserted directly into the CPU face for small I/O expansions without additional modules.
Step 2: Evaluate Memory & Program Size
For simple machine control, lower-end Siemens S7 1200 G2 CPUs are sufficient. However, if your application involves data logging, extensive PID loops, motion control, or OPC UA data publishing, opt for a higher-specification CPU with greater work memory and load memory capacity.
Step 3: Assess Communication Needs
