nkazi Posts: 1 Rating: (0)	Hi Im new at Automation and have met my first problem. I want to intergrate the Atlas Copco Compressor Controller to the current system Im working on. Both the Compressor Controller and the Combox power on but Im having problems communicate with the Compressor Controller via the OpenPMC. Can anyone give me typical solutions I can try for this?

You can have an idea of the problems users have faced through the following links: - Collection of threads discussing communications between Atlas Copco equipment and Siemens PLCs: https://support.automation.siemens.com/WW/llisapi.dll?query=atlas+copco&func=cslib.cssearch&content=adsearch%2Fadsearch.aspx%3Ftab%3D2&lang=en&siteid=csius&objaction=cssearch&searchinprim=_searchinprim_&nodeid=99&x=16&y=8&cssearchengine=NEW&x=0&y=0 - Mostly, the communication link selected is Profibus-DP, with an Atlas Copco MKIV module. See for example the posts (and sample code) provided by our friend uel123 in this thread: How to program Atlas Copco If the network or material you are working with are different, please update us with as much information as you can, maybe someone here on the forum will be able to provide some more hints. Hope this helps, Daniel Chartier
