Resumen del manual
Example 2: parameter [A][B] A=3 (2 bits), B=200 (8 bits) With a 2-dimensional array parameter like the one shown above, the block bit fields are allocated as: Block = 0000000 000aab bbbbbbb(Binary). 16.3.10 pkt : Packet Number Format: 0iiiiiiiB (LSB) 0jjjjjjjB 0kkkkkkkB (MSB) This is the divided packet number kkkkkkkjjjjjjjiiiiiiiB (Binary) for transferring a single parameter set. 16.3.11 prm : Parameter ID Format: 0pppppppB (LSB) 0qqqqqqqB (MSB) The Parameter ID indicates the parameter type. When transferring parameters (see "Part V Parameter List" below) individually, this field is used to identify the parameter being transferred by its parameter ID. 16.3.12 idx : Data Index Number Format: 0iiiiiiiB The data index number indicates the first array number of the array from which transfer starts. 30 16.3.13 len : Data Length Format: 0lllllllB Data length indicates the transfer array length minus 1 for individual parameter transfer when the parameter contains a character string or other similar array structure. 16.3.14 data : Parameter Data Format: 0dddddddB (0eeeeeeeB) (0fffffffB) (0gggggggB) (0hhhhhhhB) : : Parameter data indicates the parameter value. Data that is the size of the number of arrays equivalent to len + 1 follows. For the structure of one data item, the length depends on the data bit width, as shown below. dddddB + 1 Number of Data 1 -7 1 8 -14 2 15 -21 3 22 -28 4 29 -32 5 Each block of data is packed from the lowest order byte first. In the case of multiple-byte data, the lowest weighted bit is the LSB of the first "data" block, and the highest weighted bit is the MSB of the final "data" block. The following shows an example of how data would be divided for transfer in the case of 32-bit data. 76 5 4 3 2 1 0 data0: 0 [bit06] [bit05] [bit04] [bit03] [bit02] [bit01] [bit00] data1: 0 [bit13] [bit12] [bit11] [bit10] [bit09] [bit08] [bit07] data2: 0 [bit20] [bit19] [bit18] [bit17] [bit16] [bit15] [bit14] data3: 0 [bit27] [bit26] [bit25] [bit24] [bit23] [bit22] [bit21] data4: 0 0 0 0 [bit31] [bit30] [bit29] [bit28] 31 17 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. An Individual Parameter Send can also be used to issue some command to the Instrument, and the Individual Parameter Request can be used to check Instrument status information. Data Receiver Data Sender Operation IPR > Send Request (Optional) < IPS Data Transfer See "Part V Parameter List" for information about how parameters can actually be sent. 32 Part V Parameter List How to Read the Tables Number Base Notation "Size" indicates the parameter value bit width as a decimal value. The bit field position of "Block" as a decimal value. Values used in the explanations under "Description" are all decimal values, unless specified otherwise. Values other than those described above are all hexadecimal. R/W Field The R/W field indicates whether an IPR (Individual Parameter Request) read operation or IPS (Individual Parameter Send) write operation is enabled. 18 System Parameters These parameters make it possible for an external device to check the status of the Instrument and for an external device to command some operation of the Instrument. 18.1 System Information Parameter This parameter is a container for system information.
