⚙️ What is the ET 200SP Distributed Controller?
The ET 200SP is Siemens' modular I/O platform for decentralized automation. When equipped with a CPU module (like CPU 1510SP, 1512SP, or 1515SP), it functions as a standalone PLC, capable of real-time processing, motion control, and PROFINET communication—all in a compact footprint.
Designed for cabinet-mounted installations, it allows system integrators to create efficient and scalable automation architectures without sacrificing performance or diagnostics.

❓ Frequently Asked Questions (FAQs)
Q1: Is the ET 200SP a PLC or just remote I/O?
A: When equipped with a CPU module, it becomes a fully functional PLC with integrated PROFINET, not just I/O.
Q2: Can I expand the ET 200SP system easily?
A: Yes. It supports hot-swappable, modular I/O, and up to 64 modules per station, depending on power limits.
Q3: Does it work with TIA Portal?
A: Absolutely. It is fully integrated into TIA Portal for programming, monitoring, and diagnostics.
Q4: Are fail-safe models available?
A: Yes. Siemens offers F-CPUs (e.g., CPU 1512SP F-1 PN) for safety applications up to SIL 3 / PL e.
Q5: Can I purchase the ET 200SP from PLCpartssolution?
A: Yes. PLCpartssolution supplies Siemens ET 200SP CPUs, I/O modules, and accessories with fast global shipping and excellent pricing.
