The following explains the Y output status of this product.
For details on the Y output control, refer to the following:

*1 One using the following MELSEC data link functions:
mdBdDevSetEx function
mdBdDevRstEx function
mdBdSendEx function
mdBdRandWEx function
Regardless of the Y output status, the output (Y) can be performed and data can be written to the buffer memory from a user program
and engineering tool that use a dedicated function other than above.
• A value just before changing the Y output status is retained in devices other than the output (Y).
• A user program running on Windows keeps running regardless of the Y output status (Y OUT, Y STOP, or
PAUSE) of this product. To change the program processing according to the Y output status, create a
program that reads the value of the special register (SD203) and determines the Y output status.
The Y output status of this product is equivalent to the operation status of CPU modules other than this product.
Terms used for other modules that indicate the operation status of a CPU module are replaced with the following terms:
Before replacement (the operation status of a CPU module)
RUN state
STOP state
PAUSE state

Description
A state where performing output (Y) to each module and writing data to the buffer memory from a user program are
enabled by the BUS RESET/Y STOP/Y OUT switch, remote operation, or dedicated functions
A state where performing output (Y) to each module and writing data to the buffer memory from a user program
disabled by the BUS RESET/Y STOP/Y OUT switch, remote operation, dedicated functions, or stop error
A state where performing output (Y) to each module and writing data to the buffer memory from a user program
disabled by a remote operation or dedicated functions
Description
Whether to output the output (Y) status before STOP or to clear the status can be set in parameters. When the status
is changed from the PAUSE state to Y OUT state, the output (Y) status before PAUSE is output.
The output status is saved and all outputs (Y) are turned OFF.
The ON/OFF state of the output (Y) is retained.
After replacement (Y output status)
