2. Channel No.: Composed of (Block No.)-(Channel No.). The device addresses to monitor and the conditions
for alarm occurrence and recovery are configured in the channels. When the sampled data is

5. Label: When the sampled data is output as a CSV file, this is the text displayed in the label row.
