Library concept
Project parts can be used again via the library both within the project and also in other
projects.
● Elements such as blocks, PLC tags, PLC tag tables, interrupts, HMI screens, individual
modules or complete stations can be stored both in local and in global libraries.
● Devices and defined functions can be reused.
● The global library allows for an easy exchange of data between projects.
