(2) This function can be selected only with models that support remote SP.
(3) This function can be set for heating/cooling control, but the function will
be disabled.
(4) This function can be selected only with models that support communica-

When any of the following functions is set for an Event Input Assignment
parameter, the same function cannot be set for another Event Input Assign-
ment parameter: STOP (RUN/STOP), MANU (Auto/Manual Switch), PRST
(Program Start), DRS (Direct/Reverse Operation), RSP (SP Mode Switch),
AT-2 (100% AT Execute/Cancel), AT-1 (40% AT Execute/Cancel), WTPT (Set-
ting Change Enable/Disable), CMWT (Communications Write Enable/Dis-
able), or LAT (Alarm Latch Cancel).
Turn event inputs ON and OFF while the power is being supplied. Event input
ON/OFF changes are detected for inputs of 50 ms or longer. (However, inputs
of 250 ms or longer is determined using logic operation.)
The functions are described in detail below. Event inputs 1 and 2 are taken as
examples. When using event inputs 3 and 4, substitute event input 3 for event
input 1 and event input 4 for event input 2.
When the Event Input Assignment 1 or Event Input Assignment 2 parameter
is set to STOP (RUN/STOP), control is started when event input 1 or 2 turns
OFF. Control is stopped when the input turns ON. Alarm outputs, however, will
be according to the process value.
The STOP indicator will light while control is stopped.
