SCPI

SCPI (Standard Commands for Programmable Instruments) yog ib qho kev ntsuas ntsuas cov lus programming uas tsim los ntawm cov qauv uas twb muaj lawm IEEE 488.1 thiab IEEE 488.2 thiab ua raws li cov cai ntawm IEEE 754 tus qauv, ISO 646 cov lus pauv 7-ntsis encoding cim (sib npaug rau ASCII programming) thiab ntau lwm yam qauv.
Tshooj lus no qhia txog hom ntawv, cim, tsis muaj, thiab cov ntawv luv ntawm SCPI hais kom ua.

Command String Parse

Lub tshuab computer tuaj yeem xa ib txoj hlua ntawm cov lus txib mus rau qhov ntsuas thiab cov lus txib parser ntawm lub ntsuas pib parsing tom qab ntes tus terminator (\n) lossis ib qho kev tawm tswv yim tsis dhau.
Rau example

• Valid command string:
• AAA: BBB CCC; DDD EEE;:FFF

Cov cuab yeej hais kom ua parser yog lub luag haujlwm rau tag nrho cov lus txib parsing thiab ua tiav, thiab koj yuav tsum nkag siab nws cov cai parsing ua ntej sau ib qho program.

Hais kom Parse Rule

Command parser tsuas yog parses thiab teb rau ASCII cov ntaub ntawv.
Cov lus txib parser pib hais kom parsing thaum tau txais qhov kawg cim. Lub ntsuas tsuas yog txais peb cov ntsiab lus raws li hauv qab no raws li qhov kawg cim.

• CR
• CR + LF
• LF

Cov lus txib parser yuav xaus qhov kev ntsuas tam sim tom qab ntsuas qhov yuam kev, thiab cov lus txib tam sim no yuav raug siv tsis raug.
Cov lus txib parser yog case-insensitive rau parsing hais kom ua hlua.
nws hais kom parser txhawb nqa daim ntawv luv luv ntawm cov lus txib thiab cov ncauj lus kom ntxaws saib hauv qab no.
Hauv RS485 hom, ntxiv ADDR□ chaw nyob hauv zos:: □ nyob rau hauv pem hauv ntej ntawm SCPI, qhov chaw nyob hauv zos tuaj yeem teem rau 1-32.
Nws yooj yim rau kev sib txuas lus nrog ntau yam khoom siv ntawm SCPI raws tu qauv.
Rau example: ADDR□1::□IDN? □ sawv cev rau qhov khoob
Qhov kawg ntawm cov ntaub ntawv xa los ntawm qhov ntsuas defaults rau 0x0A (LF).
Ntau cov lus qhia tuaj yeem xa los ntawm semicolon "; ".

Symbol Stipulation and Definition

Tshooj no siv qee cov cim uas tsis yog ib feem ntawm cov ntoo hais kom ua, tab sis tsuas yog rau kev nkag siab zoo ntawm txoj hlua hais kom ua.

Mark	Kev piav qhia
<……>	Cov ntawv hauv lub kaum sab xis qhia qhov parameter ntawm cov lus txib. Rau example: sawv cev rau floating point tooj sawv cev integer parameter
[……]	Cov ntawv nyob rau hauv square brackets qhia cov lus txib xaiv.
{……}	Thaum curly brackets muaj ob peb yam khoom parameter, nws txhais tau tias tias tsuas yog ib yam khoom tuaj yeem xaiv los ntawm lawv.
Peev tsab ntawv	Abbreviated daim ntawv hais kom ua.
□	Cov cim tsis muaj, nws sawv cev rau qhov khoob thiab tsuas yog nyeem ntawv xwb.

Command Ntoo Structure

SCPI cov lus txib muaj cov qauv ntoo zoo li peb theem (ceeb toom: cov lus txib parser ntawm qhov ntsuas no tuaj yeem txheeb xyuas txhua qib), qhov twg qib siab tshaj yog hu ua subsystem hais kom ua. SCPI siv cov nyuv (:) cais cov lus txib siab los ntawm cov lus txib qis.

Rau Example

Hais kom ua thiab Parameter

Ib tsob ntoo hais kom ua yog suav nrog cov lus txib thiab [parameter], siv qhov khoob los cais (ASCII: 20H).

Rau example AAA:BBB 1.234 Command [parameter]

txib

Cov lus hais tuaj yeem ua tau ntev ntev los yog hauv daim ntawv luv luv. Cov qauv ntev pab cov engineers kom nkag siab zoo dua lub ntsiab lus ntawm txoj hlua hais kom ua; daim ntawv luv luv yog tsim rau kev sau ntawv.

Parameter

Ib tus cwj pwm hais kom ua, tsis muaj parameter Rau Example AAA: BBB

Parameter tuaj yeem yog txoj hlua hom thiab nws daim ntawv luv luv kuj ua raws li ntu kawg "hais kom luv luv txoj cai"

Rau example AAA:BB □1.23

Parameter tuaj yeem ua tus lej tus nqi.

	123, +123, -123
	Floating point tooj ntawm arbitrary daim ntawv: : tsau ntab taw tes naj npawb: 1.23, -1.23 : floating point tooj sawv cev los ntawm kev tshawb fawb: 1.23E + 4, +1.23e-4 : floating point tus naj npawb sawv cev los ntawm kev sib npaug zog: 1.23k, 1.23M, 1.23G, 1.23u

Table 0-1 Cov ntawv luv ntawm Kev Sib Tw Muaj Zog

Tus nqi	Lub zog sib npaug
1 E18 (EXA)	EX
1 E15 (PETA)	PE
1E12 (TSI)	T
1E9 (GIGA)	G
1 E6 (MEGA)	MA

1E-9 (NANO)	N
1E-12 (PICO)	P
1E-15 (PEMTO)	F
1E-18 (TSI)	A

SCPI yog case-insensitive, yog li cov ntawv sau txawv ntawm tus qauv lub npe.

Rau example:

"1M" sawv cev rau 1 milli, tsis yog 1 mega. "1MA" sawv cev rau 1 mega.

Separator

Cov cuab yeej hais kom ua parser tsuas tuaj yeem tau txais kev tso cai cais. Lwm yam separator yuav ua rau yuam kev "Invalid separator".

;	Semicolon yog rau cais ob cov lus txib. Rau Example AAA:BB 100.0 ; CCC: DDD
:	Colon yog rau cais cov ntoo hais kom ua lossis rov pib cov ntoo hais kom ua. Rau Example AAA : BBB : CCC 123.4; :DDD : EEE 567.8
?	Lo lus nug cim yog rau querying. Rau Example AAA?
□	Qhov khoob yog rau cais cov parameter. Rau Example AAA:BB □1.234
