Hi everybody!
Let’s say I have three tags in an AB PLC (newData, FirstData, SecondData). Thoses tags are read by Ignition using the same provider and the same scan class. When a test is finished, the PLC put the results in FirstData and SecondData and then set the tag newData to 1 to indicate new data is avaible.
In Ignition there is a value Change script on newData. This scrip take the value of the others tags to build a JASON string and send all the data to another system using a webservice (http.post).
The question is about data sync. In Ignition, how to be sure the JSON string will contain updated value of FirstData and SecondData?
Thanks.
