3 MEMORY CONFIGURATION OF THE CPU MODULE
3.4 Files
File operation available
The following lists the file operations which can be executed to each file in the CPU module by external devices.
: Available, : N/A
*1 Modification of data in files, such as read/write from/to file register and execution of the FWRITE/FREAD instruction
*2 When the CPU module is in the STOP state, the file operation is performed by writing the FB file to the programmable controller. In the
RUN state, it is performed by online change. Note that only programs and FB files that are registered in the parameter can be written
when the operating status of the CPU module is RUN.
*3 Available only when the CPU module operation status is STOP/PAUSE. A communication error occurs when operated in the RUN state.
*4 Available only when the CPU module operation status is STOP/PAUSE. When a program tries to perform memory operation while the
CPU module is RUN, the operation is continued after the operation status is changed through remote STOP.
*5 Operation on CPU Module Logging Configuration Tool.
*6 When the operation target is the SD memory card, the operation can be performed even while the CPU module is RUN.
*7 The availability of the online change (the file batch online change of FB files and the global label setting file) differs depending on the
model and firmware version. (Page 119 File batch online change, Page 1008 Added and Enhanced Functions)
When the modules that do not support the online change mentioned above are used, the operation that is performed in the RUN state
continues after the operating status is changed by the remote STOP function.
*8 If the global label that can be accessed from the external device is set and the CPU module is in the RUN state, only read operation is
available.
*9 When the CPU module is in the RUN state, the file operation is available only when the target file is already written to the CPU module.
