STOP/RUN status change function
This function changes the STOP/RUN status of the VxWorks part at an arbitrary time.
For example, the cyclic data of the CC-Link IE Field Network function can be cleared or conditional branches of user
programs can be used.
The operation status of the VxWorks part has the following types. The status can be changed at an arbitrary time when a stop
error is not occurring on this product.
• RUN
• STOP
• Changes to the STOP/RUN status of the VxWorks part do not affect the operation on the Windows part.
• To change the STOP/RUN status by a remote operation or function, change the position of the STOP/MAIN
RUN switch to 'MAIN RUN'. If the STOP/MAIN RUN switch is in the Stop position, the STOP/RUN status will
be fixed to STOP.
• After changing the STOP/RUN status to STOP by a remote operation or a function, the STOP/RUN status
will not change to RUN even if the position of the STOP/MAIN RUN switch is changed to RUN. Change the
STOP/RUN status to RUN by a remote operation or a function.
• Even when the operating status of the VxWorks part is either STOP or RUN, the data processing of a user
program is performed. To divide program processing depending on the operating status of the VxWorks
part, use the C Controller module dedicated function (CCPU_GetCpuStatus). (MELIPC MI5000 Series
