The hardware clock holds time, and forcing is available for commissioning overrides. ## Integrated connectivity and redundancy Three communication highlights separate this CPU from a plain PROFINET controller. First, IRT (isochronous real-time) delivers deterministic cyclic data for motion axes. Second, MRP (media redundancy protocol) lets this unit act as redundancy manager in a ring of up to 50 devices – no extra switch needed. Third, MODBUS TCP is built in, so you talk to drives, HMIs, or third-party sensors without a gateway module. UDP, TCP/IP, and LLDP round out the stack. ## Memory and processing The process image handles 32 kbyte for inputs and 32 kbyte for outputs – all variables map into the image unless you explicitly bypass it. Program memory is 300 kbyte (code + data blocks). The CPU supports S7 routing, which simplifies programming across multiple subnets. Forcing outputs is enabled, a time-saver during startup when you need to bypass sensor interlocks temporarily. ## Physical fit and sourcing Dimensions are 100 mm wide, 117 mm high, and 75 mm deep – the standard ET 200SP housing. For sourcing: this CPU is an active current-design part from Siemens; lead times are met through our supply chain.","metaTitle":"Siemens 6AG1512-1SK00-2AB0 CPU 1512SP-1 PN, IRT, MRP, MODBUS","metaDescription":"Siemens S7-1500 CPU 1512SP-1 PN with PROFINET IRT, MRP redundancy, MODBUS TCP, web server, 32 kB I/O process image.
