It carries an FM 8 rating, meaning it supports up to 8 technology function modules for tasks like high-speed cam switch signals. The CPU provides 244 bytes each of process input and output image, giving it a substantial I/O footprint for a mid-range S7-300 controller. This CPU integrates a PROFINET interface with IRT (Isochronous Real-Time) support, enabling deterministic communication for motion control and high-speed applications. It also supports UDP and TCP/IP via the integrated PROFINET interface and loadable function blocks, so it can talk directly to drives, vision systems, or SCADA without an extra CP. Programming is handled through STEP 7 V5.5 SP2 or higher, with the S7-Technology option package V4.2 SP3 required for technology functions. The CPU supports LAD, FBD, STL, SCL, GRAPH, CFC, and HiGraph languages, giving flexibility across engineering teams. ## Key specs that matter for fit The I2t rating of 1 A²·s is the thermal energy the CPU's internal electronics can withstand during a short-circuit event — useful when coordinating with upstream breakers in a panel. It has 4 integrated counters with a preset value of 10, and supports up to 32 modules overall. Forcing is supported, which is handy during commissioning to override outputs without changing the program. The CPU is isolated, meaning the logic and I/O circuits are galvanically separated from the backplane. PROFIsafe is not supported on this CPU, so if you need fail-safe communication to safety I/O, you'll need a different processor. MPI and DPV1 are also not available — communication is PROFINET-native. RS 485 is present, so you can still hook up legacy drives or HMI panels via a point-to-point link. ## Panel integration and expansion The CPU measures 120 mm wide, 125 mm high, and 130 mm deep — standard S7-300 form factor that snaps onto a DIN rail. It supports up to 8 CPs for LAN and 8 CPs for PtP communication, plus 2 CPs for DP, so you can expand the network interfaces significantly without changing the CPU. Routing is supported, which means you can access PROFIBUS or PROFINET devices through the CPU's own interface from the engineering station. A GSD file is available from Siemens support for integrating the CPU into a PROFINET master system.","metaTitle":"Siemens 6ES7317-7TK10-0AB0 SIMATIC S7-300 CPU 317-7TK DP, SF","metaDescription":"Siemens 6ES7317-7TK10-0AB0 CPU 317-7TK DP, SFB type, FM 8, 244-byte I/O, PROFINET IRT, STEP 7 V5.5 SP2+.
