Digital input (DI) of H-DI-A module
The types below can be selected for the digital input (DI) of the H-DI-A module.
Function mode 1:
−
Memory area transfer (ENABLE terminal is used)
After area selection setting, the actual area is changed by detecting the ENABLE edge.
−
Control RUN/STOP transfer
−
Alarm interlock release
Function mode 2:
−
Memory area transfer
The actual area is changed approximately 2 seconds after area selection setting.
−
Control RUN/STOP transfer
−
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
PLC, etc.
Memory area selection, Control RUN/STOP selection and Alarm interlock release
Selection or release can be performed depending on the open or closed state of terminal numbers 1 to 8.
For memory area selection, configure an external contact circuit or use a contact output signal from the
PLC, if necessary.
