I'm using Python to communicate with the PI SOAP Web Services (we don't have the REST-web api available yet unfortunately), which works fine for now.
I am however, running into minor problems writing data to PI tags due to time synchronization differences between servers.
Is there a convenient way to write data to a PI tag at the current server time? Providing the SOAP function with "*" as date does not work.
Below is the code I currently use:
def insert_value(self, tag, value, time=datetime.datetime.now()): aos = self.client.factory.create("ArrayOfTimeSeries"); timeseries = self.client.factory.create("TimeSeries"); aof = self.client.factory.create("ArrayOfTimedValue"); timedvalue = self.client.factory.create("TimedValue"); timedvalue.value = value timedvalue._Time = time aof.TimedValue = [timedvalue] timeseries.TimedValues = aof timeseries._Path = tag aos.TimeSeries = [timeseries] # write to server self.client.service.InsertPIData(aos,"InsertDuplicate")
