20 Individual Parameter Operations
There are two parameter unit operations: Individual Parameter Transfer and Individual Parameter Request.
For one session, in response to an IPR (Individual Parameter Request) from an external device, this Instrument returns an
IPS (Individual Parameter Send) or the session is concluded when the external device or this Instrument spontaneously
sends 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 Instrument
and Individual Parameter Request may be used to check Instrument status information.
21 Parameter Set Transfer
21.1 Communication Modes
21.1.1 One-way and Handshake
In order to ensure maximum speed for bulk dumping of Parameter Sets, the data format is different from the data format
used for Individual Parameter Send. Data is transferred as-is, using the Model's memory image.
Parameter Sets can be transferred by bulk dump using the message exchange types described below.
• One-way mode Parameter Set send/receive
• One-way mode Parameter Set send request send/receive
• Handshake mode Parameter Set send/receive
• Handshake mode Parameter Set send request, receive rejected, error notification send/receive
With the one-way mode, the sending device sends data and ends the session without regard to the response of the receiving
device. This mode is best for one-way transfers from a sequencer or similar device. With the handshake mode, the sending
device sends the data and then waits for a response from the receiving device before advancing to the next session. This
is a high-speed mode in which there is no time wasted waiting.
See "Part VI Parameter Set List" for details about Instrument parameter sets.
