(2) Relative to the stored value or set value of specific buffer memory, the setting
increments is applied as indicated below.

The value is stored in increments of 1

The value indicated without a decimal
0.1 point is stored in increments of 0.1
Example) To specify the temperature for the set value to 200.0 degree Celsius
when the input range is set to 36 (setting increments: 0.1), set Set
value (SV) setting (buffer memory address: 22
For applicable buffer memory, refer to Decimal point position (buffer memory
address: 1 to 4

(3) After the input range setting is changed, the temperature process value turns to "0"
for about 8 seconds.
(4) When the input range is changed, the set value of the following setting items might
shift to be outside the setting range, since the setting range shifts along with the
input range change.
If this occurs, the setting item outside the setting range will detect a write data
error (error code: 4).
To avoid this, before changing the input range, set the value of the setting item
within the input range which has been changed.
• Set value (SV) setting (buffer memory address: 22
• Alert set value 1 to 4 (buffer memory address: 26

(5) To determine the set value change, you must turn on Setting change command
(YnB).
