[Procedure 3] Acquire the parameter is performed reading (instrument → master).
(The following is an example of command response from instrument to master after procedure 2 when SV,
time, SV No. of pattern 1 and step 1 are following setting.)
Acquiring
・SV = 111.1
・Time = 22:33 (H:M)
・SV No. = No.4 (Example of command = 01030A045700160021000000047555)
Master →
Instrument
Command Setting contents
Slave address 01H Set the instrument number (MODE 8 of sending command to KP.)
Function cord 03H Set the function cord 03 (= 03H) for reading analog setting values.
Number of data 0AH 10 byte (0AH) = 5×2 byte data
SV(H) 04H
SV(L) 57H
[Reference number 49006] Acquire SV value.
0457H → (Decimal notation) → 1111 → (SV decimal point=1) → 111.1
Time, hours or
minutes (H)
00H
Time, hours or
minutes (L)
16H
[Reference number 49007] Acquire high order (HHH: ) of time.
0016H → (Decimal notation) → 22
Time, minutes or
seconds (H)
00H
Time, minutes or
seconds (L)
21H
[Reference number 49007] Acquire low order ( : LL) of time.
0021H → (Decimal notation) → 33
[Not Use] 00H
[Not Use] 00H
[Reference number 49009] is not in use reference number.
Erase the stored data for dummy data (indefinite).
SV No.(H) 00H
SV No.(L) 04H
[Reference number 49010] Acquire SV No..
04H → (Decimal notation) → 4
CRC(L) 75H
CRC(H) 55H
Set the cord for error check.
(When it is MODBUS_RTU protocol, set the error check value of CRC-16.)
When perform reading of program pattern (step) information, performed reading of each
parameter after registration (writing) of corresponding pattern No. and step No. of reference
49003/49004.
