9.2.8 Putting a Label
If users want to use a jump instruction, they have to put a label on the network to which the
execution of the program jumps. A label is put at the right side of a network number. Besides, if the
project created is a project for a DVP series PLC, the label put on a network must be a P device.
The P devices in an AH500 series CPU module are automatically assigned by the system, and can
not be used by users. If the project created is a project for an AH500 series CPU module, the label
symbol users type must be a unique label. The label symbol users type in a project for an AH500
series CPU module does not need to be declared in a symbol table. Please refer to user manuals for
more information about P devices.
If users want to specify a label in an instruction, they do not have to type a colon in front of the label.
The steps of putting a label are as follows.
(1) Click the right side of the network number at which a label will be put.
(2) If the project created is a project for a DVP series PLC, users have to type a P device number.
If the project created is a project for an AH500 series CPU module, users have to type a label
symbol. Press Enter on the keyboard after a P device number or a label symbol is typed. The
system will automatically put a colon at the right side of the label.
