9.2.9.2.1
For operation mode: high-speed (profile only)
Save target data: profile
When the memory allocation is "double buffer"
The change program operation and the memory usage states transition as shown below.
When the memory allocation is "entire area (overwrite)"
The memory is deleted when a change program operation is performed.
When reading profiles, if the profiles were read by specifying 1 (erase the read profiles) in byErase
for LJV7IF_GET_PROFILE_REQ or LJV7IF_GET_BATCH_PROFILE_REQ, the read profiles (batch)
and the profiles (batch) older than those are deleted from memory. During high-speed
communication, sent profiles are deleted from memory when the controller sends the acquired
profiles.
When performing an operation to continuously get profiles from the controller, make sure that the
speed at which the PC reads and deletes files is faster than the speed at which data is saved on
the computer.
9.2.9.2.2
For operation mode: advanced (with OUT measurement)
Save target data: storage target data (OUT measurement values/profiles)
When the memory allocation is "double buffer"
When the memory allocation is "entire area (overwrite)"
See "9.2.9.2.1 For operation mode: high-speed (profile only)".
