The operation log capacity in backup memory (SRAM) is determined by the defined [SRAM Records].
The capacity of the backup memory (SRAM) that you can use for the operation log depends on the type of display unit and the space used by other data. For details about backup memory (SRAM), please see the following.
2.3 About the Display Unit's Internal Data
To check the backup memory (SRAM) usage, from the [Project (F)] menu, point to [Information (I)], select [Project Information (I)], and then select [SRAM Information].
Calculation
Operation Log Capacity (in bytes)
440 + 420 (Data size for 1 log) × [SRAM Records]
Calculation Examples
When [SRAM Records]=300
440 + 420 × 300 = 126440 bytes (approximately 124 KB)
