- Description
The Siemens 6ES7512-1CM03-0AB0 is a SIMATIC S7-1500 compact CPU 1512C-1 PN with 32 integrated digital inputs, 32 digital outputs, 5 analog inputs, and 2 analog outputs, plus 400 KB program and 2 MB data memory. It has one PROFINET IRT interface with an integrated 2-port switch and requires a SIMATIC Memory Card to operate.

Selection Notes
With 32 integrated digital inputs and 32 outputs plus 5 analog inputs and 2 analog outputs onboard, this compact CPU covers a mid-size machine's I/O without distributed modules, unlike the smaller S7-1200 CPUs that top out at 14 DI/10 DO. The IRT PROFINET interface with isochronous mode down to a 500 microsecond OB cycle supports motion or synchronized drive control that standard RT PROFINET cannot guarantee. A SIMATIC Memory Card is mandatory for operation, so card capacity should be sized to the 400 KB program / 2 MB data working set plus any recipe or log data before ordering.
Applications
Suited to mid-size machine control requiring high I/O density onboard, and applications needing PROFINET IRT isochronous communication for coordinated drive or motion control.
