OPC WuT (Web-IO-Thermo) with Freelance 2013
We connect WuT Web-IO with OPC Client from Freelance 2013. We get the temperature and can see it in a grafic. The problems are
1) It isn't possible to create a measuring point.
2) There is a warning then "tag type" should be created -"Bei dem OPC-Item 'WuTOPC.Box1.T.0.' konnte der konstante Teil nicht ermittelt werden"
Please have a look at the attached file.
It's a warning and might be because of source of data point is constant value real datatype. Does it allow to map/create variable in freelance ? after saying OK to this message.
I have translated warning message in English and it says " "tag type" should be created - "In the OPC item '. WuTOPC.Box1.T.0' was the constant part can not be determined ".
So, if after saying ok warning message if does not allow ready value, You need to create OPC tagtype.
How to create and what is tagtype that info you can get from online freelance help. Press F1 from CBF, go to Contents tab > Under OPC items > OPC_FB-CLASS Creation. You get everything you are looking for related to OPC tag-type.
