j
Each of the above set values has the suffix
j
, which should be replaced with 0 if
the value is positive and F if the value is negative when they are input. The pa-
rameter range of each of the above set values is 0000 to 9999.
The hysteresis set command consists of the command code CA00 and parame-
ter. Set the hysteresis value to the parameter.
Refer to pages 214 to 216 for the details of the set value command.
Setting Example
Set the L set values to 0000 and the H set values to 2000 with the hysteresis set
to 0010. Each Comparison Result Flag is turned ON when the scaled conversion
data is as follows.
