The S7-1500 is the performance controller in the SIMATIC line, used on large machines, process skids and plant-wide automation. We supply CPUs, digital and analogue signal modules, system and load power supplies, front connectors and memory cards, plus SIPLUS variants for extended-environment installations. Its I/O ecosystem is shared with ET 200 distributed stations.
The CPU, its memory card and the front connectors are separate order codes — a CPU alone will not run.
Match the module's front connector type (screw vs push-in) to what is already wired in the rack.
System power supply (PS) and load power supply (PM) are different devices with different roles — confirm which one is missing.
Check firmware version compatibility with the TIA Portal project before replacing a CPU.
Frequently asked questions
Does a replacement CPU come with a memory card?
No — the SIMATIC memory card is ordered separately, and an S7-1500 CPU will not run a program without one.
Can S7-1500 modules be mixed with ET 200 I/O?
Yes. The S7-1500 and ET 200MP/ET 200SP families share I/O concepts and are designed to work together over PROFINET, which is why most plants standardise on both.
