■Number of output items
• The number of spool output items is counted from receipt of an S6F23 (Spooled data request) transfer request.
• Previous values are not retained due to a reset. (Values are not retained after reset.)
• Counted as output items when the spool was discarded.
• Counted as one item by spool transmission success. (When there is a W-bit, when a secondary message is received).
• The final result is stored before the Spooling relay or Spool outputting relay is turned OFF.
• Two words each are used for the number of spool items, maximum number of data items, and number of output items, so
take care not to overlap with other register settings.
■Abort reception upon spooling setting
• If "Not Communication Upon Abort Reception For Spool Message" is enabled in the [Control] tab of the option settings and
"Skip and continue transfer" is configured, "Skip and continue transfer" is prioritized, and communication is not
disconnected when an abort message is received during spool transmission. At times other than spool transmission,
communication is disconnected when the conditions are met.
• In the case of "Abort Frame Reception" in the [SECS Error Notification Setting] tab of the option settings, a relay notification
is performed regardless of the "Abort Reception Upon Spooling" setting.
■Important points regarding spool definition settings
• The SECS/GEM communication software does not turn OFF the sending request relay unless message sending is
completed. Accordingly, when primary messages are to be sent, it is necessary to describe the handshake response
monitoring timer processing of the SECS/GEM communication software at the programmable controller CPU. At this time,
the spooling relay turns ON when there are messages subject to spooling.
• When the spooling relay is ON, the SECS/GEM communication software does not send a message when the equipment
attempts to send a primary message not subject to spooling. However, S1 and S9 related messages are sent.
■Considerations when switching the power ON or OFF
• Before turning OFF the power of a C Controller module, disable spooling or hold the Mode switch of the C Controller
module from RUN to STOP, and then wait 3 seconds or more. To prevent corruption of logs and spooling files, all file writing
is stopped. Furthermore, put the Mode switch back to RUN before turning ON the power. Operation may be affected
because there are limits on file access during start-up.
• Before turning OFF the power of the C intelligent function module, disable spooling or unmount the SD card (by holding the
Mode switch of the C intelligent function module from the center to the SELECT position for 3 seconds or more). To prevent
corruption of logs and spooling files, all file writing is stopped. Furthermore, put the Mode switch back to the center before
turning ON the power. Operation may be affected because there are limits on file access during start-up.

7.10 Spooling Function (non-GEM version)
Description
Select the spooling operation after the spool buffer becomes full.
• Complete Transmitting Spool/Complete Removing Spool: After the number of spool items reaches
the maximum, spooling is not possible again if the entire spool has not been transferred or deleted.
• Spooling Possible With Empty Spool Buffer: After the number of spool items has reached the
maximum, spooling is possible, even when previous spool data remains, when the spool buffer could
be emptied by spool transfer, etc.
Select the operation when an abort message is sent for a spool transmission message.
• Transmit Is Interrupted To Hold Message: The transfer of the spool is canceled. At the next transfer,
the transfer is started from a message that returned an abort.
• Skipped And Transfer Is Continued: The spool transfer message that returned an abort is skipped,
and transfer is continued automatically from the next spooled message. Transfer is completed when
there is finally a spooled message.
Select the format of the spool start time, spool release time, and spool-full time to be stored to the
specified register.
For details on each format, refer to the following:

Configure the register to store the time the spool started.
Configure the register to store the time the spool cancelled.
Configure the register to store the time until the maximum number of spool items was reached.
