6ES7 313-6CF03-0AB0

Siemens 6ES7 313-6CF03-0AB0 is the CPU 313C-2 DP configuration. The CPU separates fixed working memory from MMC load memory. Its 64 KB work area holds the executing program and associated data, while the Micro Memory Card supplies load memory up to 8 MB and maintenance-free program retention. Increasing the card capacity therefore does not resolve a working-memory limit. The CPU uses a 24 V DC rated supply, with a permissible range of 20.4-28.8 V DC and typical power loss of 10 W. Its diagnostics buffer retains up to 100 entries, supporting investigation of CPU and network events before restart or program changes.

Local control uses 16 digital inputs and 16 digital outputs; analog signals require suitable expansion or distributed modules. Three integrated counting channels support frequency measurement up to 30 kHz, and three PWM outputs operate up to 2.5 kHz. These technology functions share hardware resources with the configured digital terminals.

The first communication interface supports MPI at up to 187.5 kbit/s. The second is an isolated RS485 PROFIBUS DP interface for master or slave operation at up to 12 Mbaud. As a DP master the CPU can serve up to 32 slaves; the station data and address limits still apply. This variant does not provide isochronous DP master operation or constant bus cycle time.
