[F30] Accumulated Flow Value Hold Setting - SMC Networks PFMC7501-L Operation Manual

■[F30] Accumulated flow value hold setting

Select the setting in which the accumulated flow measurement value is stored to the internal memory.
The default setting is not to store the accumulated flow when the power supply is turned off.
This function enables the accumulated flow value to be stored in permanent memory every 2 or 5 minutes.
The internal memory life varies depending on the number of times that the memory device can be accessed,
so this must be taken into account before use.
If the product is operated 24 hours per day, the maximum writable limit will be as follows:
Data memorized every 5 minutes --- 5 minutes x the number of times the memory device can be accessed
(3.7 million cycles) = 1850 million minutes = Approx. 35 years
Data memorized every 2 minutes --- 2 minutes x the number of times the memory device can be accessed
(3.7 million cycles) = 740 million minutes = Approx. 14 years
