OTL Syntax

StringTerm Measure.GetDeviceServiceNameFromEvent(EventValue event);

Description

The GetDeviceServiceNameFromEvent term accepts an EventValue term and returns a string which contains the device and service name of the device and service that caused the event. By using this term, an OTX sequence can wait for an Event raised by a device receiving a new result and then evaluate which service of that device caused the event.

The returned string value will be composed out of two parts: "devicename.servicename", where "devicename" and "servicename" are the names as given by the corresponding DeviceSignature.

Return Value

The Term returns the value, see table below.

In OTX, Terms are categorized according to its return data type!
