6.6.2.1 Readable PLC Data with PLC On-board

The table below shows the size and number of programs of the PLC data which can be handled by CNC.

(*1) 256 K steps and 512 K steps are the optional specifications.
When the PLC data is edited using the on-board with the M800VS Series or M80V Series, PLC data may not be read due to
the restriction of memory capacity even if the data size is within the range described above. To edit the PLC program using
the PLC on-board, make the total size of device comments less than 1 MB.
When the data is too large to be stored in the editing memory of the PLC on-board, an error message appears when the data
is read. The data which has been read can be displayed and edited. However, some data has not been read in such a case;
therefore, it is not suitable for checking the operation of the sequence program. Use GXWorks2 to check the operation of the
sequence program of the data which causes an error when the data is read into PLC on-board.

6.6.2.2 The Number of Ladder Files and PLC Message Files Available on One Project

Maximum number of ladder files and PLC message files available on one project is as follows: number of ladder files +
number of PLC message files < 125. (The 125th and subsequent files cannot be read.)
If the total of ladder files and PLC message files exceeds 125, develop the project in either of the following methods:
 Read only the necessary PLC message files to the PLC on-board. (PLC message files are not read automatically when you
start PLC on-board. Thus select [NC FILE] - [OPEN] to read them.)
 Use the multi-project function to set the number of files per project to 124 or less.
