3317 Parameter TransferThere are two parameter operations: Individual Parameter Transfer and Individual Parameter Request.A single session is concluded only when this Instrument returns an IPS (Individual Parameter Send) in response to anIPR (Individual Parameter Request) from an external device, or when an external device or this Instrument spontaneouslysends an IPS. If this Instrument received an IPS, the value of the applicable parameter is changed.Depending on the function of a parameter, Individual Parameter Send may be used to issue a command to the Instrumentor Individual Parameter Request may be used to check Instrument status information.17.1 Two-way Communication17.1.1 Example : Data send in response to send request to the Instrument17.2 One-way Communication17.2.1 Example : Data send to Instrument from external source17.2.2 Example : Data send resulting from Instrument operationData Receiver Data Sender OperationIPR Send Request IPS Data TransferData Sender Data Receiver Operation IPS Data TransferData Receiver Data Sender Operation IPS Data Transfer
