3.6.3 Functional description
(1) Digital input function (DI-A)
The digital input function can be used to select the memory area in the control unit to which the DI-A
module is connected, to select control RUN/STOP or alarm interlock release.
After the contact is closed, it takes a short time until the action of this device is actually
selected. Therefore, pay attention to this delay time if the device is used together with a
sequencer, etc.
Memory area selection, control RUN/STOP selection and alarm interlock
release
Selection or release can be performed depending on the open or close state of terminal numbers 1 to
8.
For memory area selection, configure an external contact circuit or use a contact output signal from
the sequencer, if necessary.
