Control of Siemens Simotion over XML-OPC

[OZI]

HI,

I am trying to control a Siemens Simotion unit over XML-OPC. With a XML-Browers we can access the data inside the Simotion. But it was not possible to open a connection with CVIXMLLoadDocument
 

Does anyone of you have experience with XML programming?

Does CVIXMLLoadDocument need a special format or is this defined in XML? That means does CVIXMLLoadDocument look for a special document? Or how does it work ?
 

Greetings
Oliver

Hi Oliver,

I can not answer your question (no experience in XML programming). The reason of this reply then is just the comment that we use a slightly different approach for controlling a S7-200 SPS, using a Siemens OPC server.

The general question is if CVIXMLLoadDocument is OPCXML DA 1.0 compatibel?

in the CVI examples XMLSample and xmlTree the command CVIXMLLoadDocument is used, may be is gives you some idea?

(PS to my former note: the software we use is PC Access)
