ZG2-DSU User’s Manual
Possible Number of Logging Data
Possible Number of Logs to Internal Memory
*1 Logging is possible up to 65,000 times regardless of the number of connected Sensor
Controllers and number of preset tasks. When the number of saves reaches 65,000
times, logged data is overwritten starting with the oldest data.
*2 When the number of saves reaches 5,120 times, logged data is overwritten starting
with the oldest data.
Possible Number of Saves to Memory Card
When logging ends, logged data is saved to Memory Card as a single file.
The possible number of saves differs according to the amount of remaining space on the
Memory Card, number of connected Sensor Controllers and the number of preset tasks.
Refer to the following table.
The numerical values in the table above are provided for reference only. Please note that the
number of saves may fluctuate depending on the setup status even with the same number of
channels or tasks.
