Override I/O auto assignments

The Mapping view contains two override columns. To change an I/O assignment, enter the new parameter in one or both of the two override columns.

The information in other columns cannot be edited directly. You can also reassign an object to a different scan group in the IO Devices view, in which case the new assignment will be reflected in the Mapping view.

Note: If an object is already deployed, changing any of its I/O assignments in the Mapping view will change the object’s status from "Deployed" to "Deployed with pending configuration changes."

To override the DI object and scan group assignment that was made in the IO Devices view, enter the value you want in the column Device.ScanGroup Override. Naming restrictions for the Device.ScanGroup Override value are as follows:

• The value must contain one DI object name and one scan group name contained by the DI object, separated by a period (.).

• The value cannot start or end with a period.

• The value cannot have any leading spaces.

• The I/O reference cannot be longer than 380 characters.

To override the object and attribute name, enter the value you want in the column Object.Attribute Override. Naming restrictions for the Object.Attribute Override value are as follows:

• The value cannot have any leading spaces.

• The I/O reference cannot be longer than 380 characters.

You can change attribute information using the Object Editor (after checking out the object), instead of overriding values in the Mapping view. However, if you enter the specific I/O reference for an attribute in the Object Editor (manual configuration), it will no longer appear in the Mapping view. Only attributes configured for I/O automatic assignment appear in this view.
