It provides non-volatile program and data storage, allowing the CPU to retain user programs, data blocks, and configuration settings without battery backup. The card slots directly into the CPU module and is recognized as the load memory for the controller. Licensed HVAC controls technicians, industrial electricians, and automation specialists working on PLC-based control systems install and replace this component during commissioning or after a card failure.\u003c\/p\u003e\n\u003cp\u003eThis memory card is used in industrial automation environments where SIMATIC S7-300 CPUs require onboard load memory for program storage. Typical applications include building automation controls, industrial process equipment, HVAC unit controllers built around S7-300 hardware, and other machine control panels. The card is inserted during initial PLC setup or as a direct replacement for a failed or corrupted MMC in an existing installation. It supports standard MMC program transfer operations via the CPU front panel slot.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eNon-volatile MMC storage retains program data without a battery\u003c\/li\u003e\n  \u003cli\u003eDirect load memory replacement for SIMATIC S7-300 CPU modules\u003c\/li\u003e\n  \u003cli\u003eCompact card form factor fits the standard S7-300 CPU front-panel slot\u003c\/li\u003e\n  \u003cli\u003eSupports user programs, data blocks, and configuration retention\u003c\/li\u003e\n  \u003cli\u003eLightweight at 0.066 pounds for easy handling during installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style MMC load memory replacement for Siemens SIMATIC S7-300 series PLC CPU modules that accept a front-panel MMC slot.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified industrial electrician or PLC technician familiar with SIMATIC S7 hardware. Power down the PLC and place the CPU in STOP mode before inserting or removing the memory card to avoid data corruption or hardware faults. Program transfer to the card is typically performed using the SIMATIC Manager or TIA Portal software following Siemens documented procedures. Consult applicable NEC guidelines and the site safety plan before working inside any control panel.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.066 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 4.173 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 3.661 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 0.197 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 88762144545\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SIEMENS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6ES79538LP310AA0\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SIEMENS","offers":[{"title":"Default Title","offer_id":51384025743666,"sku":"6ES79538LP310AA0","price":1921.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312677374.jpg?v=1782615238","url":"https:\/\/voomisupply.com\/products\/siemens-6es79538lp310aa0-mmc-memory-card-plc-storage","provider":"Voomi Supply","version":"1.0","type":"link"}
