This non-volatile storage module is used to house compiled STEP 5 user programs, including organization blocks, function blocks, and statement lists. By storing control logic independently of the CPU backplane battery, the module ensures program integrity during power outages, reducing recovery time and preventing data loss in critical industrial environments such as manufacturing lines and power generation facilities.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eNon-volatile 8 KB EPROM memory storage.\u003c\/li\u003e\n\u003cli\u003eUV-erasable design for reusable program cycles.\u003c\/li\u003e\n\u003cli\u003eDirect interface with Simatic S5 CPU front-loading slots.\u003c\/li\u003e\n\u003cli\u003eRobust plastic housing for protection against electrostatic discharge and EMI.\u003c\/li\u003e\n\u003cli\u003eLow power consumption, drawing directly from the host CPU backplane.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThis submodule is essential for Simatic S5 PLC systems where long-term program retention is required without reliance on volatile RAM or battery-backed memory.
