9.4 Register/Read/Delete User Frames
9.4 Register/Read/Delete User Frames
The following explains registering, reading, and deleting user frames in the Q series C24 flash ROM or buffer memory.
When registering, reading and deleting the user frames in the flash ROM, try to register them using the utility package (GX
Configurator-SC) of the Q series C24.
This section explains how to register, read, or delete user frames from the programmable controller CPU.
(1) Type of user frames
*1 Data contained in user frames used for registering and reading is arranged in the same way as data in user frames used
for registering in or reading to the flash ROM.
Use the arrangement described in this section as a reference, and register and read user frames. User frames can also
be registered in the buffer memory, but the user frame for the fixed format section should be registered in the flash ROM
whenever possible.
*2 A user frame cannot be overwritten for registration. To reregister a user frame having the same number, first delete the
current user frame and then reregister.
*3 Check the registration status of the user frame number from GX Configurator-SC.
(2) Devices that can register/read/delete user frames
Conduct registering, reading, and deletion of the user frame from the sequence program when data communication is not
being conducted with external device.
