3.7 Libraries

With the TIA Portal you can create independent libraries from different project

elements that can be easily reused.

Advantages

 Simple storage for the data configured in the TIA Portal:

– Complete devices (controller, HMI, drive, etc.)

– Controller programs, blocks, tags, monitoring tables

– HMI image, HMI tags, scripts, etc.

 Cross-project exchange via libraries

 Central update function of library elements

 Versioning library elements

 Fewer error sources when using control blocks through system-supported

consideration of dependencies

Recommendations

 Create the master copies for easy reusability of blocks, hardware

configurations, HMI images, etc.

 Create the types for the system-supported reusability of library elements:

– Versioning of blocks

– Central update function of all usage locations

 Use the global library for the exchange with other users or as central storage

for the simultaneous use of several users.

3.7.1 Types of libraries and library elements

Generally there are two different types of libraries:

 "Project library"

 "Global library".

The content consists of two storage types each:

 "Types"

 "Master Copies"

1 2 ... 49 50 51 52 53 54 55 56 57 58 59 ... 73 74
