Changing Reference Addresses and Lengths
The I/O map shows the beginning Reference Address or Length assigned to the
Remote I/O Scanner for %I, %Q, %AI, and %AQ data.
You can change any reference address or length in the I/O map. If you change a
reference address after entering modules of that data type in the Remote Drop, you
can have the software automatically reassign their reference addresses to begin at the
new I/O map reference address by responding “Y” at the prompt.
I/O Map base address changed; adjust I/O presently inside map boundaries? (Y/N)
Viewing/Editing the I/O Map
If Auto I/O Map is ON, when you press ESC from the Remote Drop rack configuration
screen as instructed on the previous page, enter Y in response to the following prompt
if you want to view or edit the I/O map.
This Remote Drop’s I/O Map has been automatically configured, view it? (Y/N)
You can also view and edit the I/O map by returning to the Remote I/O Scanner
configuration screen at any time during Remote Drop configuration.
If Auto I/O Map is OFF, when you press ESC from the Remote Drop rack configuration
screen, the configuration is saved, and the display returns to the bus configuration
screen. If you want to view or edit the I/O map, zoom (F10) to the Remote Drop rack
configuration screen, then zoom (F10) to the Remote I/O Scanner configuration screen.
The Logicmaster software will not prevent you from configuring an I/O conflict. Be
careful not to enter an address that overlaps the references assigned to other modules.
If any module references are outside the I/O map, the screen displays:
***** NOTE: Configured modules(s) are outside the I/O MAP *****
