1.3 Self-configuration
The self-configuration function automatically detects the Option Modules connected to the Machine Controller and
automatically generates the files for the Module configuration definitions and the detailed definition of each Module.
Executing self-configuration will greatly reduce the system startup procedure.
1.3.1 Executing Self-configuration
The methods used to execute self-configuration are described below.
( 1 ) Setting the CNFG DIP Switch Pin and Cycling Power
(MP2200/MP2300/MP2300S/MP2310)
Self-configuration can be executed by turning ON the CNFG DIP switch pin on the Machine Controller and turning the
power OFF and then ON again. The result will depend on the setting of the INIT DIP switch pin.
The DIP switch is not normally used for the MP2100M/MP2500MD. For these Machine Controllers, use the MPE720
as described next.
( 2 ) Using the MPE720
Start the MPE720, start the Engineering Manager, and then select
Order - Self Configure All Modules from the Main
Menu. Alternatively, select the Module for which self-configuration is to be executed in the Module Configuration
Window, and then select
Order - Module Self-configuration from the Main Menu.
Refer to 1.4.1 Displaying the Module Configuration Window on page 26 for the procedure to display the Module
Configuration Window.
The result depends on the command that is used, as described below.
After executing self-configuration, always save data to flash memory so that the results of self-configuration
are saved in the Machine Controller.
When self-configuration is executed, I/O registers are allocated in order of the slot numbers from the leading
register. If register allocations have been changed manually, the register allocations will be overwritten when
self-configuration is executed.
To keep any register allocations that were changed manually, do not use self-configuration again, but rather
manually allocate I/O registers for the added Option Modules.
Refer to 1.4.3 ( 2 ) Manual Allocation of I/O Registers on page 28 for information on manually allocating I/O
registers.
