7 MANAGEMENT OF DATA IN THE PLC CPU
(3) Batch-writing/reading parameters
Since the parameter type (e.g. PLC parameter, network parameter) is not
differentiated in the PLC CPU, the parameter type cannot be specified to perform
write/read to/from PLC.
If you specify the parameter type in the PC side window, the parameters of all
types are batch-written.
POINT
• If you do not choose a paste (read from PLC) destination project but select a
folder and paste (drop) the source project, a new project is created and only the
parameters are read.
Its project name is "GX Developer project".
If the project of the same name exists in the folder, the project name will be "GX
Developer project
" ( indicates a number in numerical order, starting from 1).
• After write to PLC, reset the PLC CPU or MELSECNET/H remote I/O.
Reset must be performed to make the written parameters valid.
For reset operation, refer to the user's manual of the PLC CPU being used.
