1. Sigmadue sigmaPAC CU 02 Quick Guide 8 3 Ascon I O Function Blocks An undemanding and yet less efficient method of managing the CANopen network is to do things manually and having all the network in mind edit a DCF file with the rules and formats stated by CiA in the document Cia DS306 The task is made more friendly by using the Ascon I O Function Blocks FBs directly from OpenPCS programming tool Ascon I O FBs have two main purposes e Make accesses to I O modules both for read write field values and parameters configuration data e Mask the CANopen communication protocol structures and controls Ascon I O FBs are based on the standard FBs included in the communication library as described in CANopen Extension for IEC61131 3 User manual Edition March 2005 Systec Electronic most of which are compliant with the CiA specification CiA Draft Standard 405 CANopen Interface and Device Profile for IEC61131 3 Programmable Devices version 2 0 The I O accesses are made by CANopen Master agent that is resident on the CPU To make it easy the CANopen master uses a series of basic Function Blocks such as Send Receive SDOs PDOs etc By the way these FBs are also used by the more structured ASCON I O FBs Nev ertheless the User may want to use the basic FBs The user can find it in the standard OpenPCS libraries of FBs We recommend however the use of ASCON I O library of Function Blocks 12. sigmadue CPU CU 02 Quick Guide 012 S E R ES Quick Guide Q G Sigmadue CU 02 1a 09 12 Cod J30 478 1ACQGS2E Copyright 2007 2008 ASCON spa All rights reserved No part of this document may be stored in a retrieval system or transmitted in any form electronic or mechanical without prior written permission of ASCON Spa ASCON has exercised care in preparing this book and believes the information contained within to be accurate The ASCON Products are subjected to continuous improvement in the pursuit the technological leadership These improvements could require changes to the information contained within this book ASCON reserves the right to change such information without notice ASCON makes no warranty of any kind expressed or implied with regard to the documentation contained in this book ASCON shall not be liable for any incidental and consequential damages in connection with or arising out of the use of this book sigmadue gammadue and deltadue are trademarks of ASCON spa All the other tradenames or product name are trademark or registered trademarks ASCON spa Via Falzarego 9 11 20021 Baranzate Milano Italy Fax 39 02 3504243 http www ascon it support ascon it Prerequisites Using this manual Current Documentation on the Internet Chapter 1 Hardware Installation Mechanical installation 1 1 1
