This equipment manual provides essential information for the Siemens SIMATIC ET 200SP CPU 1512SP-1 PN (Article number: 6ES7512-1DM03-0AB0). It is intended for qualified personnel responsible for installation, commissioning, and maintenance. Always refer to the full documentation for detailed system-spanning functions.
Product Overview
The CPU 1512SP-1 PN is a high-performance controller for the ET 200SP distributed I/O system. Key features include:


- Integrated PROFINET interface with 3-port switch.
- Support for PROFINET IO, IRT, and isochronous mode.
- Firmware version V3.1 with enhanced security and diagnostic functions.
- Support for S7-1500 Motion Control technology objects.
- Integrated web server for remote diagnostics and monitoring.
Wiring and Connections
Proper wiring is critical for safe operation:

- Supply Voltage (X80): The 24V DC supply is connected via a 4-pin plug. Pins 1L+ and 2L+ are for 24V DC, while 1M and 2M are for ground.
- PROFINET Interface (X1): Port 3 is integrated into the CPU housing. Ports 1 and 2 are available via an optional BusAdapter.
- MAC Addresses: The device has four MAC addresses (one for the interface, three for the ports) used for protocols like LLDP.
Status and Error Displays
The CPU features several LEDs to indicate operational status:

- POWER (PWR): Indicates supply voltage status.
- RUN/STOP: Displays the current operating mode (Green = RUN, Yellow = STOP).
- ERROR: Flashes red when an error occurs.
- MAINT: Indicates maintenance demand (Yellow).
- LINK LEDs: Indicate Ethernet connection status for PROFINET ports.
Technical Specifications
- Supply Voltage: 24V DC (permissible range 19.2V to 28.8V).
- Work Memory: 400 kbyte for program, 2 Mbyte for data.
- Operating Temperature: -30°C to 60°C (horizontal installation).
- Dimensions: 100mm (W) x 117mm (H) x 75mm (D).
- Weight: Approx. 265g.
Safety and Cybersecurity
Siemens strongly recommends implementing a holistic industrial cybersecurity concept. Ensure the CPU is protected against unauthorized access by locking the front flap and using password protection. Always apply the latest product updates to mitigate cyber threats.
