Check items before the start of continuous logging
■Operation modes and functions
Before starting continuous logging, check the operation mode and the settings of each function.
Item
Operation mode
A/D conversion enable/disable setting function
Averaging processing function
Warning output function (process alarm)
Input signal error detection function
Interrupt function
When the above functions have been set and an error has occurred, continuous logging cannot be started. In addition,
settings cannot be changed during continuous logging. Thus, configure the above settings before starting the continuous
logging.
■Continuous logging status monitor
Check whether the A/D converter module can start continuous logging or not with 'Continuous logging status monitor'
(Un\G61). Check that Continuous logging start request waiting (1) is stored.
■Continuous logging cycle setting value
The logging cycle of the continuous logging function is obtained by the following formula: Conversion cycle (5s)  (Value set
in 'Continuous logging cycle setting value' (Un\G280)). Set a desired logging cycle with 'Continuous logging cycle setting
value' (Un\G280). Check the set logging cycle with 'CH1 Logging cycle monitor value (s)' (Un\G452).

1.15 Continuous Logging Function
Description
Check that the simultaneous conversion mode or inter-module
synchronization mode is set.
Check that the A/D conversion is enabled for the channel to be used.
Check that the sampling processing or moving average processing is set.
When using the warning output function (process alarm), check that each
parameter has been correctly set.
When using the input signal error detection function, check that each
parameter has been correctly set.
When using the interrupt function, check that the continuous logging data
storage has been set as the condition target.
