ATTENTION
The area is cleared if a channel stops (output 0 if stoppage).
Command junction

_ab_CH3_FINDEN
It outputs maximum/minimum values of
temperature entered while the
instruction junction is being set as 1.
Until the bit of the area is set as 0, it
maintains the maximum/minimum
value. But, the function does not work if
the channel stops although the area is
allowed.

_ab_CH0_ALMEN
_ab_CH1_ALMEN
_ab_CH2_ALMEN
_ab_CH3_ALMEN
If the junction bit to select alarm
function provided by module (Process
alarm/Rate Change alarm), Enable or
Disable is set as 1, the alarm function is
allowed and it may output the alarm if it
is within alarm condition depending on
the settings. But, the function does not
work if the channel stops although the
area is allowed.

_ab_CH0_RJCDS
_ab_CH1_RJCDS
_ab_CH2_RJCDS
_ab_CH3_RJCDS
Command junction prohibiting or
allowing cold junction compensation
(RJC) of a channel. If the bit is set as 1,
it does not support RJC. In general, the
area is set as 0 (allowed). But, in case
of Type B sensor, it does not support
RJC regardless of the area instruction.
