2-1 Purpose
The purpose of this document is to supply a complete description of
AsconBasicIOLib Library project.

Caution
This library can be used only with the CU-02 unit.
2-2 Description
AsconBasicIOLib is a Function Block library enabling the access of Ascon SpA
sigma
due line devices from OpenPCS programming environment. Thanks to the FBs,
the user does not take care of communications details related to CANopen
1
protocol,
but he simply has to access to the available functions of the individual devices.
The library gives the access to the basic functions of the IO modules. For advanced
functionalities of the sigma
due modules see the AsconAdvancedIOLib documentation.
The following is the list of FBs present in the library.
1. A complete series of firmware function blocks implementing the CANopen communi-
cations primitives are available for the user: these FBs grant the access to the module
directly through the CANopen protocol messages. For further details, see “
CANopen
extension for IEC61131-3
” User Manual available on the installation CD.
