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.
