Communication is via MPI (Yes) and S7 communication; SCL is supported as an optional high-level language. The CPU can also connect to PROFIBUS via a CP 342-5 module. ## Memory and program execution Integrated RAM is 12 KB (12 KB / 4K instructions), with a maximum expandable FEPROM of 8 KB. The CPU retains all blocks with a battery; without battery it holds 72 bytes of memory bits, times, counters, and data. The command set covers binary logic, bracketed operations, arithmetic (fixed and floating point), jump functions, and block calls. Program organization can be linear or structured, with up to 8 nesting levels and 8 priority classes. ## I/O and timing The CPU supports 64 bytes of inputs and 64 bytes of outputs, with a maximum of 256 bytes of process image. It has a software clock with adjustable preset time (150 ms) and a cycle time range from 1 ms to 6000 ms.","metaTitle":"Siemens 6ES7313-1AD03-0AB0 CPU 313, 12 KB RAM, MPI, EOL Hot","metaDescription":"Siemens 6ES7313-1AD03-0AB0 CPU 313 for S7-300, 12 KB integrated RAM, MPI, S7 communication, 24 V DC, 8 W.
