Output Signal Details - Mitsubishi Electric MELSEC iQ-R Series User Manual

Output signal details

The following shows the details on the output signals from a high speed data logger module to a CPU module.
Precautions
Turn ON each output signal after 'Module READY' (X0) turns ON. Otherwise, a setting file may be corrupted or an unintended
operation may occur.
The output signal will be enabled when it is turned OFF to ON.
In addition, since the system does not turn the output signal ON to OFF, turn it ON to OFF, and OFF to ON to
perform again.
File access stop request (Y2)
When the file access stop request is turned ON, the file access is stopped.
Clear file access stop request (Y3)
Turn this signal ON when the file access stop request is sent by mistake.
After requesting the file access stop, the file access can be restarted when the SD memory card has not been replaced and
the file access stop cancel request is turned ON.
The module operation is stopped; therefore, turn ON 'Setting renew request' (Y8), restart the module operation in
Configuration Tool, or update the setting in Configuration Tool. (If the auto logging function is enabled, logging will restart by
turning ON 'Clear file access stop request' (Y3). Executing a request such as a module operation start request is not
required.)
Clear INFO LED request (Y7)
If this signal is turned ON when data is missing, free space of the SD card has decreased, resend buffering has started, or the
saved folder names/file names are duplicated, the following operations will be performed.
• INFO LED is turned OFF
• 'INFO LED status' (X7) is turned OFF
• Clear the 'INFO LED indication factor' (Un\G12)
Setting renew request (Y8)
This signal is used to update settings written to a high speed data logger module and allow the module to operate according
to the updated settings.
Settings are not updated in the following cases:
• The module operations such as updating settings, stop, restart, and logging file clear are performed using "Diagnostics"
screen or output signal
• During module initialization processing
• During module stop processing
• The settings are not written in the high speed data logger module.
Turn this signal OFF after 'Setting renew status' (X8) turns ON.
Time synchronization request (YB)
When the time synchronization request is turned ON, the time of the module will be synchronized according to the time
synchronization settings. (When the time of the CPU module has been changed, turn this signal ON after wait for more than 1
second.)
Turn the 'time synchronization request' (YB) OFF after turning it the 'time synchronization timing' (XB) ON.
