( 2 ) Self-configuration after Adding Devices Such as SERVOPACKs
For self-configurations after having added network devices such as SERVOPACKs, leave the switch INIT to OFF in
step (2) of the above procedure, then perform the rest of the steps.
For network devices with existing definitions files, correctly connect and turn ON the power to the devices when
executing self-configuration.
Power Restart and RAM data Clear
If the INIT switch on the DIP switch on the Basic Module is ON and the power is turned ON, RAM data will be cleared.
Also, flash memory data will be read and RAM data will be overwritten when the INIT switch is OFF and the power is turned
ON. In either case, the RAM data will be cleared by turning the power ON. Therefore, always save data to the MP2300 flash
memory before turning OFF the power when writing or editing programs.
For information on how to save data to flash memory, refer to
4.2.3 ( 1 ) Saving to Flash Memory
on page 4-21 (MPE720 Ver
6.
) or
4.3.2 ( 6 ) Saving to Flash Memory
on page 4-40 (MPE720 Ver 5.
).
Turning OFF Power After Executing Self-configuration
Do not turn OFF the 24-VDC power supply to the MP2300 after executing self-configuration until the definitions data has been
saved to flash memory in the MP2300. If the power is turned OFF somehow before the data is saved to flash memory, execute
self-configuration again.
If register allocations have been changed manually since the last time self-configuration was executed, the
register allocations will return to the default settings when self-configuration is executed again. If the SVR is
set to disabled (UNDEFINED), the setting will return to enabled. To keep the changed register allocations,
do not use self-configuration, but manually make the register allocations for added devices and refresh the
definitions file.
