Ascon Tecnologic Function Blocks Libraries
In this chapter are listed the libraries part of Ascon Tecnologic automation CD and
those available in the CU-02 firmware device. For each library the complete list of
function blocks with a brief description is also indicated. For more details please
refer to the specific documentation.
6-1
AT_CU02_Cpu_Lib
The
AT_CU02_Cpu_Lib
is a library which allows to access the control unit (CU-02)
resources. These FBs allow the user to set and manage the CANopen network
activities: diagnostic, failure management of the connected devices, syncronization.
Some of the Function Blocks must be considered
system function blocks
because they
implement some particular functionalities dedicated to the CANopen network overall
managment (see the “
IEC 61131-3 Function Block Library
” [
11
] manual for details).
Note:
These are system Function Blocks.
6-2
AT_IO_Modules_Basic_Lib
The
AT_IO_Modules_Basic_Lib
is a library that allows the
OpenPCS
programming environment to access the Ascon Tecnologic’s
sigma
due
devices.
These FBs simplifies the configuration and the access to CANopen
1
I/O modules.
A list of available I/O FBs follows:
