Programming is done via STEP 7 V5.2 SP1 or higher, with HW update required for the SIPLUS hardware variant. All common languages are supported: LAD, FBD, STL, SCL, CFC, and even HiGraph® and GRAPH for sequential control. The FM 8 rating indicates 8 channels of motion functionality, suitable for positioning and speed control on conveyors, feeders, or mill drives. The I2t rating of 1 A²·s suggests a moderate short-time withstand, adequate for most 24 V DC load circuits. CE marked, EN 50155 sections 4, 5, 12 compliant. T1 category, Category 1, Class A/B. Temperature range -40 to 70 °C. Confirm current lifecycle status with RFQ if freezing BOM.","metaTitle":"Siemens 6AG1315-2AH14-2AY0 SIPLUS S7-300 CPU, FM 8, -40..70°","metaDescription":"Siemens 6AG1315-2AH14-2AY0 SIPLUS S7-300 CPU for harsh environments.
