This component includes factory-preloaded firmware tailored for the AS511 communication protocol, enabling efficient data transfer between the text display unit and the connected programmable logic controller. It serves as the primary storage medium for screen configurations, variable mapping, and essential system parameters required for HMI operation. As this component reached its end-of-life status in early 2005, it remains a vital spare part for operators managing legacy automation systems in industrial processing and mining environments.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eNon-volatile EEPROM storage architecture ensures data retention without the need for battery backup.\u003c\/li\u003e\n\u003cli\u003eOptimized for direct integration with the Simatic TD20 operator terminal.\u003c\/li\u003e\n\u003cli\u003ePre-configured with AS511 protocol support for reliable serial communication.\u003c\/li\u003e\n\u003cli\u003eCompact plug-in design for easy installation into the terminal expansion slot.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e6AV3971-1CA02-0CA0\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSiemens\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeries\u003c\/td\u003e\n\u003ctd\u003eSimatic TD20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMemory Capacity\u003c\/td\u003e\n\u003ctd\u003e128 Kbytes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInterface\u003c\/td\u003e\n\u003ctd\u003e48-Pin Header\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e5 VDC (Host Powered)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 50 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-20 to 70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eEnsure the TD20 terminal is completely powered down before attempting to insert or remove the memory submodule to prevent electrical damage.\u003c\/li\u003e\n\u003cli\u003eHandle the module by its edges to avoid electrostatic discharge (ESD) damage to the sensitive onboard components.\u003c\/li\u003e\n\u003cli\u003eAlign the 48-pin connector carefully with the host slot to prevent bent pins or improper seating.\u003c\/li\u003e\n\u003cli\u003eVerify that the module is fully seated in the expansion slot before restoring power to the system.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch3\u003eIs this module compatible with newer HMI models?\u003c\/h3\u003e\n\u003cp\u003eNo, this memory submodule is specifically designed for the legacy TD20 operator interface and is not compatible with modern Siemens HMI systems.\u003c\/p\u003e\n\u003ch3\u003eDoes this card require a backup battery?\u003c\/h3\u003e\n\u003cp\u003eNo, the module utilizes internal EEPROM technology, which provides non-volatile storage and does not require battery buffering to maintain data integrity during power loss.\u003c\/p\u003e","brand":"Siemens","offers":[{"title":"Default Title","offer_id":44003528048730,"sku":"6AV3971-1CA02-0CA0","price":99.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0710\/5957\/0778\/files\/wm_1_e3790664-b780-4a17-9c6d-9c3ba3ae0955.jpg?v=1788373576","url":"https:\/\/www.spareoil.com\/products\/6av3971-1ca02-0ca0-siemens-simatic-memory-submodule","provider":"SpareOil Automation","version":"1.0","type":"link"}
