(Page 40 Operating status)
*1 For devices that can be specified, refer to the following:
Page 29 Devices that can be specified as triggers
*2 Whether a trigger has been satisfied is determined during the END processing in a scan of a CPU module.
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' of a recorder module. (Page 104 Recording
status area (Un\G1500 to 3199))
• If a recording startup trigger is satisfied again after it is satisfied and data is accumulated, the accumulated data is
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
