The 244 byte input and 244 byte process-image output areas define the maximum I/O data the CPU can exchange each cycle — enough for a few hundred digital points or a couple of analog modules before you hit the addressing ceiling. The integrated DP interface runs RS 485 and is isolated, supporting both DP master (client) and DP slave (server) roles — the client mode requires a CP and a loadable FB, while the server mode is native. Routing is supported only when the active interface is present, so plan the network topology accordingly. ## Programming languages and memory backup — what the spec table tells a commissioning engineer This CPU supports LAD, FBD, STL, SCL, GRAPH, and HiGraph. The 8 function blocks (FM 8) are available for technology functions. The backup time of 6 weeks means the CPU retains the RAM content for up to 6 weeks without external power. The maximum data size per communication job is 256 bytes — relevant when configuring data exchange with a CP or an HMI. Forcing is supported, which lets you override I/O states during commissioning without changing the program. The depth includes the front connector and the bus connector to the adjacent module, so leave clearance for the cabling channel.","metaTitle":"Siemens 6ES7313-6CF03-0AB0 CPU 313C-2 DP, 244 byte I/O","metaDescription":"Siemens 6ES7313-6CF03-0AB0 CPU 313C-2 DP PLC with 244 byte inputs/outputs, integrated DP interface, RS 485, 6-week backup.
