4 CONFIGURATION
Note: The status of the I/O can be monitored in Cscape Software.
Preliminary configuration procedures that apply to SmartStack™ Modules are contained in the hardware
manual of the controller you are using. Refer to the Additional References section in this data sheet for a
listing of hardware manuals.
Selecting the I/O Map tab provides information about the I/O registers, which are assigned to a specific
SmartStack™ Module and where the module is located in the point map. The I/O Map is determined by
the model number and location within the SmartStack™. The I/O Map is not
edited by the user.
