Basic PLC interfacing Circuits

Post by ultrasonicâ„¢ on Fri Aug 27, 2010 11:26 pm

this basic circuit is use to easily interface a specific hardware into a computer by means of Software Commands.... by d way before d i ko muproceed sa wa pa kabalu unsa ng gnapasabot sa HARDWARE, mao na xa ang emng electronic circuit na gus2 nmu ipa-control sa computer.., dis ckt is applicable in Both different OS(operating system): its either in XP or windows 98 kng sa kuan pa universal Xa... applicable kaau xa, ky wa xay rason nga mamublima ka pg-interface sa emng hardware into d computer... advantage of dis circuit : no need a feedback blocker ky tungod sa Opto-coupler pa lang wa nay physical connection ang emng circuit sa LPT "DB25" in short isolated xa.... based sa diagram only one LOAD lng na xa.. kng gus2 nmu daghan kag LOAD nga controllon nga separated command... i-multiple nmu ang emng circuit basi sa emng plano..........



optional device are : diode 1N4001 pwde na xa wla sa circuits......... ky ang main purpose lng nya dha ky EMF stabilizer (electromotive force Stabilizer)....

DB25 = PRINTER PORT or mas familiar sa tawag na PARALLEL PORT containing of 25pins

DB9 = SERIAL PORT containing 9pins


Now ang pangutana??? unsay kalahian sa XP sa Windows 98 nga pareha lng mn cla OS ???


ang XP ang iyang gnahatag sa iyang LPT port ky only 3 volts or below with a low current rating meaning dli ni xa applicable ipagamit kng transistorize type lng ang emng circuit ky tungod dli kaya i-sustain sa emng transistor... kng baga dli xa ka saturate ky tungod gamay kaau xa ug voltahe ug current nga dli enough sa BASE terminal

while ang Windows98 ky 4.5V - 5V ang iyang gnahatag... nga kaya mkapa-switch-on ug switching transistor..

dagdag info na pud... now if gus2 nmu i-revise ang circuit naa na na sa inyu... pwde na xa... for e.g: 12V SPDT relay ang available sa emu.... & den kana ang inyung itaod of course 12V jud ng Supply ninyu... now i-besure lng na ang inyong resistor sa BASE terminal sa transistor must be higher dan d original printed in d schematic... ky of course madaot jud na xa,,.. my advice value ky mga 5kohm - 10kohm... hehehehehe & other component ky i-maintain lng ang value.....




now abwt sa SOFTWARE? in short PROGRAM nnyu....?

naa na na sa inyu alangan namag ihatag nku pati ang SOURCE CODE dba jejejeje
kamu na ang mg-xplore ana (-_-)K, ..... bastah ang most common nga gnagamit nga SOFTWARE ky C or C++
