The menu keys change as follows.
The massage to confirm the suspension appears when the suspend menu is pressed.
If you suspend the reading, specify and read the PLC data which has not been read with the [NC FILE] - [OPEN] function.
Refer to "6.13.3 Opened Screen".
Note
(1) When a message below appears while reading PC data, the number of device points that is set in the PC parameter and
the number of device points that is set in the multi-project parameter are not matched.
There is a possibility that the device number/type which are used by the ladder circuit may change when reading PC data
is continued. Therefore, do not use the ladder circuit being read.
After having formatted the storage area once, you need to review the number of device points in PC parameter and multi-
project parameter, and rewrite the ladder again.
For a project with labels or a structured project, when device points do not match, a message "Device points set in the
parameters and device points in NC do not match. The reading from PLC or writing to PLC is suspended." is displayed
and is not read.
The reading from PLC or writing to PLC is suspended." is displayed and is not read.
(2) Install MELSEC software when operation mode is GX Works2. The following message is displayed when reading PLC
data of a project stored in CNC if MELSEC software is not installed. Restart CNC again and execute the same procedure.
If the error message is displayed again, contact Mitsubishi Electric representative in your region.
The software to read out the project created with GX Works2 is not installed.
Contact Mitsubishi representative in your region.
(3) The following message is displayed if symbolic information is not written in CNC when a project with labels or a structured
project is stored. In this case, PLC on-board operates as a project without labels is stored.
The project is created as "project with labels" or "structured project", however, the symbolic information is not stored.
If the project is edited, it may lead to loss of the consistency with the symbolic information.
