Runs FBD, LAD, SCL (optional), STL; 48 kbyte memory holds ~16 K instructions. Forcing and single-step available under change control. ## Documentation and data retention Retentive data is preserved for 6 weeks at 40°C ambient typical, which supports the data integrity requirement during power-loss scenarios in validated systems. The STEP 7 project and HW Config file remain the primary verification references for IQ/OQ. No firmware auto-update mechanism is present; the firmware version is locked at delivery, preserving the audit trail. ## Panel integration – physical constraints The module occupies 60 mm on the ET 200S rail. Depth is 75 mm, height 119.5 mm. A narrower DP master module variant (35 mm) exists, but this is the standard interface module. The integrated RS-485 port handles PROFIBUS DP; bus termination must be verified during commissioning. I/O mapping is fixed at 244 bytes input and 244 bytes output, with no expandability – the memory is locked at 48 kbyte.","metaTitle":"Siemens 6ES7151-7AA10-0AB0 IM 151-7 CPU, 48 kbyte","metaDescription":"SIMATIC ET 200S IM 151-7 CPU with 48 kbyte integrated work memory; supports FBD, LAD, SCL, STL, and PROFIBUS DPV1.
