It supports programming in LAD, FBD, STL, SCL, GRAPH, HiGraph, and CFC, and requires STEP 7 V5.2 SP1 or higher with the corresponding hardware update. ## Memory and Backup The integrated backup provides 6 weeks of retentive data retention at 40 °C ambient temperature, covering inputs, outputs, memory bits, DBs, timers, and counters. The maximum process image size is 256 bytes, and the I²t rating for the module is 0.5 A²·s. ## Communication and Expansion The CPU includes an integrated MPI interface and RS 485 port, and can connect to PROFIBUS as a client (via CP and loadable FB) or as a server. Up to 4 CPs for LAN and 8 CPs for PtP communication can be added, but the CPU itself has no integrated PROFIsafe support and routing is not available. The module is not expandable and has no adjustable parameters for the process image; forcing is supported. No official lifecycle status or successor is recorded in the available evidence. Confirm fit against the existing S7-300 rack and the required STEP 7 version before specifying.","metaTitle":"Siemens 6ES7314-1AG13-0AB0 CPU 314, 256 I/O, 40 mm","metaDescription":"Siemens S7-300 CPU 314, 256 digital I/O, 6-week backup, 40 mm wide.
