Generation Of Libraries - GE Multilin G650 Manual

5 SETTINGS 5.9 LOGIC CONFIGURATION (PLC EDITOR)
5.9.4.7 ADD A LIBRARY
Click on the "LIB" button and select the corresponding file.
Users can build their own libraries and distribute them in their projects in an easy way.
The manufacturer provides default libraries such as ORs, ANDs of 3 up to 8 inputs, besides timers (pickup-dropout) and
key examples.

5.9.5 GENERATION OF LIBRARIES

Libraries can contain a set of operations grouped in a single graphic object being formed by inputs, outputs and operations
Working with libraries follows the same procedure as working in the main project menu, the only difference is that the inputs
and outputs to the library must be selected as external inputs and outputs. The rest of variables are internal variables used
in the logic compilation.
The name assigned to the inputs and outputs of the library and to the library itself will be ones used to represent the library
as an object in the main project.
Internal variables inside the libraries will be assigned randomly when compiling.
These libraries are saved in the LIB folder in order to be used in further projects
5.9.5.1 LIBRARY EXAMPLE
Go to the main menu File >Library > Open Library
> New Library
5
Open a new library or modify an existing one, in this example a timer library is going to be displayed Timer (Pkp-Dpt).lib as
shown on Figure 5–50:
Figure 5–50: TIMER (PKP-DPT).LIB CONFIGURATION EXAMPLE
Green and blue signals are internal inputs and outputs used in the library and are not going to be accessible to the user
when working in the main menu outside the library environment. The white boxes (T_Input, T_Pickup, T_Dropout,
T_output) are inputs and outputs to the library that are going to be accessible to the user to connect the library in the main
application to create virtual outputs to be sent to the relay.
