Labels

Labels include global labels and local labels.

Global labels

The global labels are labels that can be used in programs and function blocks. In the setting of a global label, a label name, a
class, a data type, and a device are associated with each other.

Local labels

The local labels are labels that can be used only in declared POUs. They are individually defined per POU. In the setting of a

local label, a label name, a class, and a data type are set.
For the local labels, the user does not need to specify devices. Devices are assigned automatically at compilation.
