5.17.4 Built-in PLC (Built-In Edit Function)

To use built-in PLC (built-in edit function) to edit the sequence programs created and edited on GX Works2, the following
restrictions must be taken into account.
 Overall restrictions
When a sequence program containing more than 11 contacts is written to the CNC controller, the built-in edit function may
display it incorrectly.
 Restrictions when creating programs with labels
When a program is created after simple project (with labels) is selected on GX Works2, built-in PLC (built-in edit function)
does not display labels and function blocks, and display the actual ladder (ladder with labels and functional blocks complied)
to which actual device is assigned.
Since symbolic information cannot be modified by built-in PLC (built-in edit function), when sequence programs are read to
GX Works2 again after editing, symbolic information and sequence program do not match, resulting in the following error. Do
not edit sequence programs with the built-in edit function when writing symbolic information.
Note that the built-in PLC (built-in edit function) does not support ST language. Edit programs using ST language with GX
Works2.

5.17.5 Smart Safety Observation

User safety sequence program can be created with GX Works2.
For the smart safety observation function, refer to "M800/M80 Series Smart safety observation Specification manual".

5.17.6 Enhanced PLC Security Mode

When enhanced PLC security mode is enabled on a CNC, some functions of GX Works2 which communicate with the CNC
are restricted.
For details on the enhanced PLC security mode, refer to "9.1 Enhanced PLC Security Mode".
