PLC library
10.6 PLC library
The PLC library allows for a series of subroutines that may be used for the PLC program of the
machine.
Once the library has been created, any OEM can use it to run a specific control of the machine. For
that, the OEM's PLC program will call the subroutines that are contained in the library.
It will not be possible to read the instructions of the PLC library, only call its functions to use them.
When compiling the PLC program, it will take into account whether there is a library or not. If there
is a PLC library, the PLC program and the library will be compiled together. The library must be
located in the "PRG" folder of the hard disk.
Operation
The PLC menu offers the [PLC LIBRARY] option. When pressing this softkey, it requests the PLC
password (if there is one).
After entering the right password, it displays the following softkeys:
Softkey [MAKE PLC_LIB]:
Press this softkey to create a library (plc_lib file) from the existing PLC program. The library will be
created in the "PRG" folder of the hard disk.
The PLC must be compiled before creating the library. The library will be created if there are no
compiling errors.
When creating a library, the comment that the PLC program has at the time will be copied to the
library. Once the library has been generated, it will not be possible to change the comment. A version
number should be given to identify the library.
Softkey [DELETE PLC_LIB]:
Press this softkey to delete a library. A library cannot be erased from the utilities menu, only from
the PLC menu using this softkey.
Considerations
The symbols defined in the library may be used in the following cases:
• On the screen [MONITORING / OSCILLOSCOPE].
• When editing the PLC program.
The resources used in the library will appear as used in the PLC statistics.
The labels used in the library cannot be repeated in the PLC program. Likewise, the PRG and PE
instructions cannot be defined in the library.
