The following table shows the functions assigned when an Event Input
Assignment (1 to 4) is displayed.
Setting Function
none None
stop RUN/STOP
manu Auto/Manual
prst Program Start (See note 1.)
drs Invert Direct/Reverse Operation
rsp SP Mode Switch (See note 2.)
at-2 100% AT Execute/Cancel
at-1 40% AT Execute/Cancel (See note 3.)
wtpt Setting Change Enable/Disable
cmwt Communications Write Enable/Disable (See note 4.)
lat Alarm Latch Cancel
Note (1) PRST (Program Start) can be set even when the Program Pattern parameter
is set to OFF, but the function will be disabled.
(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 communications.
Also, when a work bit is selected as event input data, Communications
Write Enable/Disable parameter cannot be selected.
When any of the following functions is set for an Event Input Assignment
parameter, the same function cannot be set for another Event Input Assignment
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 (Setting
Change Enable/Disable), CMWT (Communications Write Enable/Disable),
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.
Setting Input contact Status
Event input 1 or 2 ON STOP
Event input 1 or 2 OFF RUN
When the Event Input Assignment 1 or Event Input Assignment 2 parameter
is set to MANU (auto/manual), manual control will start when event input 1 or
2 turns ON. Auto control will start when the input turns OFF.
