*1 The upper and lower data registers change according to the 32-bit data storage method specified. For details, see Chapter 3 "Instructions
Reference" - "32-bit Data Storage" on page 3-9.
(5) D2 (Destination 2): Logged Data
Specify the device to store the data that is logged. A maximum of 212 continuous words are used starting from the set
device.
Note: The number of data registers that are used for logged data changes according to the maximum amount of logged data.
The number of data registers used for logged data is 2+6×the maximum amount of logged data.

*1 The time expressed as the number of seconds from 00:00:00 on January 1st, 1970.
(For example, if the date/time is 00:00:00 on January 1st, 2015, the value is 1,420,070,400 seconds.)
*2 The upper and lower data registers change according to the 32-bit data storage method specified. For details, see Chapter 3 "Instructions

Stores the flow rate calculated every second. The flow rate unit
conforms to the K factor and flow rate unit settings.
Stores the status including the error during FLWP instruction execution.
Stores the amount of logged data that has been recorded.
