Recording startup trigger
A recording startup trigger is used to start device and label accumulation, and satisfied when a specified device
(Page 63 Operating status)
Whether a recording startup trigger is satisfied is determined for each unit of END processing in sequence scans.
*1 For devices that can be specified, refer to the following:
Page 43 Devices that can be specified as triggers
*2 If a CPU module is operating with the constant scan set, whether a trigger is satisfied is determined between the execution of the END
processing and the start of the next scan.
If the maximum scan time for a program becomes longer than the set constant scan time, whether a trigger is satisfied is determined
during the END processing after the scan time for the program.
Precautions
• Start the recording function and check that its operating status switches to 'operating' then satisfy a recording startup
trigger. The operating status can be checked in 'In recording operation' (Un\G1501, Un\G1701, Un\G1901, Un\G2101)
a recorder module/camera recorder module. (Page 221 Recording status area (Un\G1500 to 3199), Page 271

*1 Buffer memory of a module set as the main one when configuring multiple modules
Page 67 Operation of the recording function when configuring multiple modules
• If a recording startup trigger is satisfied again after it is satisfied and devices and labels are accumulated, the accumulated
ones are discarded and the accumulation restarts.
■Period during which a recording startup trigger is enabled or disabled
A recording startup trigger is enabled except the period from when a file saving trigger is satisfied to when saving a recording
file is completed.
