Hi,
We have to read data from a balance machine connected to serial port of OPENScada server.
Measurements of object wieight are send by balance as bit sream in proprietary protocol format.
Our question is, what is the "best practice" to do this ?
Thanks in advance.
Gustavo.

Hi! To read the data under the proprietary protocol you should use "User protocol"( http://wiki.oscada.org/HomePageEn/Doc/UserProtocol ) or directly use the JavaLikeCalc ( http://wiki.oscada.org/HomePageEn/Doc/JavaLikeCalc ). This question was already discussed in the forum : http://oscada.org/en/forum/posts/adaption/custom_protocol/ .

Hi, I come back with this issue after some time.
I have read the thread in wich a similar case was discussed with socket instead serail interface.
I underestand that Roman suggested that it has to put in DAQ->javalike base calculator->controller a code like this :
//GET request
req = SYS.XMLNode("GET");
req.setAttr("URI","/");
SYS.Transport.Sockets.out_testHTTP.messIO(req,"HTTP");
test = req.text();
Where is exactly we have to put this code ? We have to create a controller function and in i have to write the code inside controller function and after that we have to relate this controller function with the controller ?
If I want to read from serial interface instead send a request by socket, could you explain me a high level steps tha we have to follow to do this ?
Thanks in advance.

Roman,
Thanks for your quickly answer.
One doubt more, where we have to put this code ? DAQ->javalike base calculator->controller ?
Thanks in advance.

Create self new JavaLikeCalc controller or use presented from DemoDB and place it.
