OPERATION PROCESSING IN C Controller
Module
This chapter shows the operation processing in a C Controller module.
2.1
Operation Processing Depending on Operating
Status
The operating statuses of a C Controller module are as follows:
• RUN
• STOP
• PAUSE
Operation processing in RUN state
RUN is a state where performing output (Y) to each module and writing data to the buffer memory from a user program
*1
are
enabled.
*1 A program in which a C Controller module dedicated function is used
■ Output when entering the RUN state
C Controller module outputs the following depending on the setting of the output (Y) when the module state is changed from
STOP to RUN. (

• The status of output (Y) which is saved in STOP state
Operation processing in STOP state
STOP is a state where performing output (Y) to each module and writing data to the buffer memory from a user program
*1
are
disabled.
The operating status can be changed with the RESET/STOP/RUN switch or the remote operation function.
If the stop error occurred in a C Controller module, the module will be in STOP state.

■
Output when entering the STOP state
C Controller module saves the output status right before the C Controller module is in STOP state, and clears all outputs (Y)
to OFF.
Operation processing in PAUSE state
PAUSE is a state where performing output (Y) to each module and writing data to the buffer memory from a user program are
disabled with the ON/OFF of the output (Y) retained.
• Even if the operating status of the C Controller module is in RUN, STOP, or PAUSE, the output (Y) can be
performed and data can be written to the buffer memory from CW Configurator, SLMP communication, and
MELSEC data link functions.
• Even if the operating status of the C Controller module is in RUN, STOP, or PAUSE, the operation
processing of a user program is performed. When splitting the program processing according to the
operating status, use the C Controller module dedicated function (CCPU_GetCpuStatus) for programming.
