File handling precautions
File reading and file writing processing
File reading and writing processes are performed in the Motion CPU main cycle. The read and write time varies depending on
the file size and main cycle length.
Power supply OFF (including reset) when performing file operations
File content is not assured if the Multiple CPU system power supply is turned OFF or the system is reset when performing file
operations other than data reading. In order to avoid file corruption, turn OFF the Multiple CPU system power supply or reset
the system after completing file operation.
Simultaneous access of the same file
An error occurs when performing the following operations. Ensure that MT Developer2 processing is complete before moving
onto subsequent processing.
• The file currently being written is accessed (read/written to) from another MT Developer2.
• The file currently being accessed (read/written to) is written to from another MT Developer2.
Simultaneous access to different files from multiple MT Developer2 applications
Up to 16 different files for the same CPU module can be simultaneously accessed from another MT Developer2.
