Choosing the size and format of the I/O data that is exchanged by the E1 Plus
Overload Relay is done by selecting Input and Output Assembly instance
numbers. Each assembly has a given size (in bytes). This instance number is
written to the Input Assembly and Output Assembly parameters. The different
instances/formats allow for user programming flexibility and network
optimization.
Mapping to the Scanner's Scan List
The Automap feature available in all Rockwell Automation scanners
automatically maps the information. If the default I/O Assemblies are not
used, the values must be changed in the scanner's Scan List.
Do this by selecting Edit I/O Parameters on the Scan List tab of the
scanner. The following screen (Figure 3.7) then appears.

IMPORTANT
The Output Assembly and Input Assembly parameter
values cannot be changed while the E1 Plus Overload Relay
is online with a scanner. Any attempts to change the value
of this parameter while online with a scanner will result in
the error message “Object State Conflict.”.
