4 To transfer data from one device to another a transaction is required. Existing
transactions cannot be modified using the IO Scanner wizard and are greyed
out. Up to 128 transactions may be created, except if you are using the M1E
PLC’s, then only support 64 transactions can be supported. To add a new
transaction, click Add. To edit a transaction created by the IO Scanner wizard,
click Edit. To remove a transaction created by the IO Scanner wizard, click
Remove.
After clicking Add to add a new transaction, you are prompted to select a
remote device. To do this, click on a remote device from the list, and press
Next.
Now you can configure the new transaction. First, select a function from the
drop down list. Second, enter 4xxxx addresses into the From and To fields
and numeric values in the Number of Registers field in the Read from Remote
Device and Write to Remote Device areas.
When you have finished editing the transaction, click Next
(To see descriptions of the functions and fields, see Editing the IO scanner
extension.)
5 The transaction summary screen displays a summary of all new transactions to
be written to the local device as well as the variously selected remote devices.
Ensure the transactions are correct and click Next
Caution: Clicking Next will proceed with the modifications and cannot be undone
once completed.
Note: Only offline databases are modified in this step.
6 Click the Update Online Devices button to update the physical devices defined
as remote devices by the wizard. This does not update the local device. That
must be done once the configuration extension editor is closed and all changes
are saved.
Caution: Online devices may be running! They must be stopped before their
contents can be modified. Before stopping any device, ensure that it is safe to do
so. Devices are restarted once the operation is complete. Also, when these
changes are complete, they cannot be undone.
Click Next.
7 Click the View Log File button to view a log of all changes made to the local and
remote devices. This file (ScannerWizard.log) may be saved and printed as
needed.
Click Finish to close the wizard and return to the Configuration Extension Editor.
