CH1 Minimum value
The minimum value of the digital operation value is stored in 16-bit signed binary value.
In the following cases, 'CH1 Minimum value' (Un\G406) is updated with the current value.
• When 'Operating condition setting request' (Un\G70, b9) is turned offonoff, and the setting is changed
• When 'Minimum value reset request' (Un\G474) is turned offonoff
■Buffer memory address
The following shows the buffer memory address of this area.

CH Minimum value
CH Minimum value (In FX3 allocation function
mode)
• For the channel to which the averaging processing is specified, the maximum and minimum values are
stored at every averaging processing time.
• When the scaling function, shift function, digital clipping function, or difference conversion function is used,
values calculated by each function are stored in Maximum value and Minimum value.
CH1 Difference conversion state flag
The difference conversion status can be checked.
Monitor value

When the difference conversion starting after 'CH1 Difference conversion trigger' (Un\G470) is changed from No request (0)
to Trigger request (1), 'CH1 Difference conversion state flag' (Un\G408) corresponding to the channel turns to Converting
difference (1).
When 'CH1 Difference conversion trigger' (Un\G470) is changed from Trigger request (1) to No request (0), 'CH1 Difference
conversion state flag' (Un\G408) is changed from Converting difference (1) to Not converted (0).
'CH1 Difference conversion state flag' (Un\G408) is Converting difference (1) during the difference conversion; Not converted
(0) if not in the difference conversion state.

When a state that data is collected in 'CH1 Logging data' (Un\G10000 to Un\G19999) changes to the stop state, 'CH1 Logging
hold flag' (Un\G409) is turned to ON (1).
When logging restarts by changing 'CH1 Logging hold request' (Un\G471) from ON (1)  OFF (0), 'CH1 Logging hold flag'
(Un\G409) is turned to OFF (0).
