11.1.1 Procedure
The following diagram describes the operation of the CPU module.
The CPU module is supplied with power.
The system enables the initialization.
 The non-latched memory is initialized.
 The downloaded program is checked.
 The parameters in the CPU module are checked.
 The parameters in the module table are checked.
 The module table in the CPU module is compared
with the actual I/O configuration.
 The I/O setting is downloaded to the I/O module.
 If the memory card is installed, whether to execute
the system copy procedure or not is checked.
Diagnosis processing:
 The memory card and other setting are checked.
 The I/O bus is checked.
 The system parameter is checked.
The data sent to the I/O module is refreshed.
 The data sent to the digital I/O module is refreshed.
 The data sent to the analog I/O module is refreshed.
 The data sent to other modules are refreshed.
Program execution:
 The user program is executed.
 The interrupt subroutine is executed.
The data sent from the I/O module is refreshed.
 The data sent from the digital I/O module is
refreshed.
 The data sent from the analog I/O module is
refreshed.
 The data sent from other modules are refreshed.
Communication service:
 The communication through the CPU module
