Run, Stop And Pause Status Operation Processing - Mitsubishi Electric MELSEC Q Series User Manual

17.2.3

RUN, STOP and PAUSE status operation processing

The C Controller module has three different operation states: RUN, STOP and PAUSE.
The C Controller module continues the user program operations in either status.
Changing the operation status also changes status of following outputs from the C Controller module:
• Output (Y) to each module
• Buffer memory writing
● Acquisition of module status
• To change the program processing according to the operation status of the C Controller module, use a function to
acquire status and perform programming.
• Operation status of the C Controller module can be acquired by the C Controller module dedicated function
(CCPU_GetCPUStatus).
(1) Operation processing in the RUN status
In the RUN status, output (Y) to each module and buffer memory writing are enabled from the user program in the
C Controller module.
(a) Output status when entering the RUN status
Output after transition of the status from STOP to RUN can be selected from the following: (Page 151,
Section 11.1.5)
• Output (Y) status saved in the STOP status (default)
• Result of operations performed after one scan
(2) Operation processing in the STOP status
In the STOP status, output (Y) to each module and buffer memory writing from the user program of the C
Controller module are disabled.
The C Controller module is also set in the STOP status when a stop error occurs.
(a) Output status when entering the STOP status
When the status changes from STOP to RUN, the C Controller module saves the output status data and clears
all outputs (Y) to OFF.
(3) Operation processing in the PAUSE status
In the PAUSE status, output (Y) to each module and buffer memory writing from the user program of the C
Controller module are disabled, with the ON/OFF output data (Y) held.
Regardless of which status the C Controller module is in (RUN/STOP/PAUSE), output (Y) operations and writing into the
buffer memory are allowed from Setting/monitoring tools for the C Controller module.
