Approved training and a standard profile for motion control using the IEC1131-3 open control programming standard are closer as a result of PLCopen-instigated work across Europe and the USA.
The training programme is almost complete, according to Eelco van der Wal, md of PLCopen. `This should be finalised before the Hanover Fair [14-19 April]’, he said. Next training committee meeting is February 13 at Mitsubishi in Ratingen, Germany.
Meanwhile, van der Wal says that the Motion Control group has been sharing function block data. As we go to press, the January 29 meeting at Siemens in Nuremberg, Germany is about to convene, with the task of merging these for a unified profile.
Moving on, PLCopen’s Communication Profile working group has made little progress. It aims to provide optional harmonised access to nodes on multiple fieldbuses during programming, configuration and operation from IEC 1131-3-based systems.
At its last meeting in Copenhagen in November, representatives from CAN, Interbus-S, DeviceNet, Profibus and P-NET merely reviewed projects.
* Work on the Safe PLC software development, to follow the proposed IEC 1508 safety standard, has now been restarted. Van der Wal told C&I that the task force is to meet at Hima, Bruhl, Germany.
