Modbus Non Volatile Memory Module
Non-volatile memory space read/writable via Modbus RTU on RS-485. Doesn't wear out like EEPROM, and data persists for 95 years without power
The KTA-299 provides 64k of non-volatile memory, accessable via Modbus RTU. The memory space is arranged as Modbus Holding Registers, allowing easy reading and writing from any industrial controller, SCADA System, PLC, etc. Data is retained in memory without power for up to 95 years (at 55°C).
The memory is stored internally using a new technology known as Ferromagnetic RAM. The advantage of FRAM over more traditional non-volatile memories such as EEPROM is that it can be written and read millions of times without wearing out and failing.
