12.5 Scan List
This can be accessed from the Scan List button on the Protocol Config screen or the Mapping button on
the Device List screen and provides a Scan List of the Data Mapping entries. To transfer data between the
I3 and remote target, a Scan List must be created that defines each transaction. Each mapping entry
(transaction) contains the source and destination registers, the number of consecutive registers
transferred, the direction of the transfer and what triggers the transfer. Typically, the number of entries
is
limited to 512
.
NOTE
: The order of the Scan List is the order in which the transactions occur. Sort functions are provided
to change the order of the list. Each entry also has an identifying index. If the device status register is
enabled and a transaction failure occurs, the status register indicates the index number of the transaction
that has failed.
