Check items before the start of high speed continuous logging
■Operation modes and functions
Before starting high speed continuous logging, check the settings of the operation mode and each function.
Item
Operation mode
A/D conversion enable/disable setting function
Averaging processing function
Scaling function
Interrupt function
When the above functions have been set and an error has occurred, high speed continuous logging cannot be started. In
addition, settings cannot be changed during high speed continuous logging. Thus, configure the above settings before starting
the high speed continuous logging.
The settings of the functions that cannot be used in the normal mode (high speed: 1s/CH) are ignored.
■High speed continuous logging status monitor
Check whether the A/D converter module can start high speed continuous logging or not with 'CH1 High speed continuous
logging status monitor' (Un\G469). Check that High speed continuous logging start request waiting (1) is stored.
■Logging enable/disable setting
When using the high speed continuous logging function, set 'CH1 Logging enable/disable setting' (Un\G535) to High speed
continuous logging (2). If Normal logging (0) is set, a logging enable/disable setting range error (error code: 1D0H) occurs.
When a logging enable/disable setting range error (error code: 1D0H) occurs in any channel, the A/D conversion stops in all
channels.
■High speed continuous logging cycle setting value
The logging cycle of the high speed continuous logging function is obtained by the following formula: Conversion cycle 
(Value set in 'CH1 High speed continuous logging cycle setting value' (Un\G590)). Set a desired logging cycle with 'CH1 High
speed continuous logging cycle setting value' (Un\G590). Check the set logging cycle with 'CH1 Logging cycle monitor value
(s)' (Un\G452).

1.16 High Speed Continuous Logging Function
Description
Check that the normal mode (high speed: 1s/CH) 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 scaling 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.
