Features:
- The rear-mounted expansion card sets an 800-process-object scale for CPU 410 SMART.
- Eight megabytes of fixed work memory and interface address limits bound the PCS 7 project.
- Card version, CPU type, project capacity, license record, and environmental rating must agree.
The CPU identifies the card during startup before establishing its available controller resources.
PCS 7 process objects and distributed I/O consume the configured memory and address areas.
The card sets capacity but does not terminate or convert any field signals.
The Siemens 6ES7653-2CM00-0XB0 PCS 7 System Expansion Card PO 800 may remain available for quotation and support beyond End-Of-Life (EOL) by the manufacturer (OEM).

Relating the expansion card to the PCS 7 project size
- Card identity: The CPU reads the SEC variant during startup.
- PO limit: The approved project remains within 800 configured process objects.
- CPU role: The card is specified for CPU 410 SMART operation.
- Project count: PCS 7 engineering records the objects that consume the available capacity.
Keeping program data inside fixed controller resources
- Integrated memory: The SEC configuration provides up to 8 MB of work memory.
- Expansion rule: This memory allocation cannot be increased on the card.
- Block planning: Program and data structures remain within the configured CPU limits.
- Commissioning check: The loaded project and runtime count are compared with the intended capacity.
Allocating distributed I/O address areas
- DP inputs: The CPU maps up to 1536 bytes from the PROFIBUS input path.
- DP outputs: A separate 1536-byte area carries PROFIBUS output data.
- PROFINET areas: Independent input and output maps each provide the documented 1536 bytes.
- Channel totals: Digital and analog channel limits apply across the configured interfaces.
Checking the physical card against the CPU configuration
- Rear slot: The SEC is installed in the documented CPU expansion-card position.
- Version pair: Hardware version 3 and firmware V2.0 match the intended project baseline.
- Environmental design: Conformal coating and the temperature limit apply to the card/CPU assembly.
- Startup evidence: CPU diagnostics confirm recognition of the exact PO 800 card.
