What this CPU brings to the rack
The 6ES7317-2FK14-0AB0: It handles 244 bytes each for inputs and outputs, which covers a medium-sized machine or line segment. The integrated PROFINET interface supports IRT for deterministic cycle times, plus UDP and TCP/IP via loadable function blocks. This CPU speaks LAD, FBD, STL, SCL, GRAPH, HiGraph, and CFC — so your programming team can pick their poison. It also supports PROFIsafe for safety-related automation without a separate safety PLC.
Wiring it in
Maximum ambient temperature is 60 °C, minimum 0 °C — fine for most panel environments, but not for a hot roof or freezer floor without climate control. Software requirement: STEP 7 V5.5 or higher. The CPU supports forcing, routing, and can act as an OPC DA server or client via loadable FBs.
