9.4 REMOVABLE CONFIGURATION BOARD

16
The Removable Configuration Board (RCB) can be installed in this controller . It retains a complete copy of the
configuration being used by the controller in which the RCB is installed. Should that controller fail, the RCB can be
removed and installed in the replacement controller. The stored configuration can then be selected as the active
configuration in the controller.
On power up, the controller will test the RCB and compare the configuration stored in the RCB to the controller's
configuration. If the RCB passes all tests and the configurations are identical, the controller will power up normally
and use the configuration from the MPU board. If a problem is detected or the configurations are different, an ON-
LINE STATUS or OFF-LINE ERROR message will be displayed. See the Maintenance section for messages.

9.5 REAL TIME CLOCK/CONFIGURATION BACKUP BOARD

17
The controller is available with an optional real time clock and configuration backup board . The configuration
backup performs the same functions as the RCB described above. In addition, the board includes a real time clock.
The time can be set using the built-in CLOCK function block in the STATN parameters. It can also be set over the
Modbus, LIL, or Ethernet network.
16
RCB requires MPU Controller board firmware version 1.31 or higher.
17
RTC/CB requires MPU Controller board firmware version 2.0 or higher.
