CH1 Continuous logging data storage flag
Simultaneous
Synchronization
conversion
Use this buffer memory area to check that data of 5000 points is stored in Logging data area of each channel during
continuous logging.
This area has two flags; 'CH1 Continuous logging data A side storage flag' (Un\G474) for checking that data is stored in the
first 5000 points area (A side) of Logging data area and 'CH1 Continuous logging data B side storage flag' (Un\G475) for
checking that data is stored in the last 5000 points area (B side) of Logging data area.
For details on the continuous logging function, refer to the following.

• Logging data storage completed (1) is stored every time logging data for the first 5000 points (A side) or the last 5000 points
(B side) has been stored.
• When logging data storage in the file registers of the CPU module is completed, Logging data storage not completed (0) is
stored in this area. With this timing, the area becomes ready to accept the next storage flag.
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
