1.1
Execution Order
The following shows the execution order of the programs in a C Controller module.
1.
Initial processing
2.
Operation processing of a program
1.2
Initial Processing
The following shows the process when turning the power ON or resetting a module.
• I/O module initialization
• Parameter check
• Multiple CPU system parameter consistency check
• I/O number assignment for the mounted module
• IP address setting for a C Controller module
• Network information setting for CC-Link IE Controller Network

I/O Access Timing
This section shows the timings for reading input (X) and writing output (Y).
Timings for reading input (X)
The timings for reading input (X) is as follows:
• When a dedicated function library (such as CCPU_X_In_BitEx/mdRandREx) is executed in a user program
• When input (X) data is read out from a peripheral device (Device/buffer memory batch monitoring of CW Configurator is
performed.)
Timings for writing output (Y)
The timings for writing output (Y) is as follows:
• When a dedicated function library (such as CCPU_Y_Out_BitEx/mdRandWEx) is executed in a user program
• When output (Y) data is written to a peripheral device (Device/buffer memory batch monitoring of CW Configurator is
performed.)
