It supports LAD, FBD, STL, SCL, GRAPH, HiGraph, and CFC programming languages under STEP 7 V5.2 SP1 or higher with the appropriate HW update. The integrated RS 485 interface provides MPI/DP connectivity; routing is supported when the interface is active. DPV1 is available via a CP and loadable FC. ## I/O capacity and fieldbus The CPU addresses 244 byte of inputs and 244 byte of outputs, with forcing supported for commissioning and troubleshooting. It supports up to 4 CPs via LAN, 10 CPs via LAN, and 8 CPs via PtP, and can act as a DP client (via CP and loadable FB) or DP server. The latest GSD file for PROFIBUS DP integration is available from Siemens. Confirm the BOM position count and the mating half before committing; the CPU requires a Micro Memory Card (MMC) for operation and is not expandable beyond its fixed 2 KB work memory.","metaTitle":"Siemens 6ES7315-2AG10-0AB0 CPU 315-2DP, 2 KB Work Memory","metaDescription":"Siemens SIMATIC S7-300 CPU 315-2DP with 2 KB work memory, 244 byte I/O, RS 485 MPI/DP, STEP 7 V5.2.
