MPC240 現(xiàn)場(chǎng)總線技術(shù)確實(shí)改變了傳統(tǒng)總線控制思維,常規(guī)的總線控制都是由一個(gè)主控CPU通過(guò)總線把子站數(shù)據(jù)拿過(guò)來(lái)進(jìn)行計(jì)算,然后根據(jù)結(jié)果再通過(guò)總線把控制要求下發(fā)給另一子站,這樣其實(shí)就是浪費(fèi)總線帶寬的資源,通過(guò)現(xiàn)場(chǎng)總線技術(shù),可以把控制分散到各個(gè)子站,而每個(gè)子站有數(shù)據(jù)采集的終端和執(zhí)行者,這樣可以有效地減輕中央CPU的負(fù)擔(dān),并且改變常規(guī)的控制模式。(今天的轉(zhuǎn)發(fā)暗號(hào)是:億維,專(zhuān)注核心控制)以前很多人都說(shuō)現(xiàn)場(chǎng)總線可以節(jié)省大量布線成本,其實(shí)線纜成本是有一些但絕不是現(xiàn)場(chǎng)總線技術(shù)為之存在的理由,它是一種改變常規(guī)控制的革新式技術(shù),它把控制的核心通過(guò)總線技術(shù)下放到各個(gè)站點(diǎn),在總線上的各個(gè)通訊站點(diǎn),不再是數(shù)據(jù)采集和控制執(zhí)行的終端,而是具有控制邏輯的大腦。 【年底大促,超低優(yōu)惠,給錢(qián)就賣(mài)?!? 采購(gòu)熱線:1 3 3 9 4 0 5 7 2 9 2(歐陽(yáng)英) ---------------------------------------------------------- (備注:只要您給出合理價(jià)格我賣(mài)給你,只要您給出同行的價(jià)格我賣(mài)給你,只要您誠(chéng)心購(gòu)買(mǎi)我就賣(mài)給你) KULICKE AND SOFFA PCB MODEL : N08001-4122-000-04 KULICKE AND SOFFA PCB MODEL : N08001-4116-000-05 KULICKE AND SOFFA PCB 8028 MAXUM CPU BOARD MODEL : N08001-4260-000-00 KULICKE AND SOFFA EFO ASSEMBLY MODEL : N08858-0068-000-01 KULICKE AND SOFFA 8028 PRS PCB AIS-640/266 410-0240-0 REV A GENERAL MICRO SYSTEMS V51X OEM BOARD PWA 91/262C REV C KULICKE AND SOFFA DUAL HEATER MODEL : N03101-1164-000-02 LG PLC DC INPUT MODEL : G6I-D22A LG PLC CNET I/F FOR RS-232C MODEL : G6L-CUEB LG PLC RELAY OUTPUT MODEL : G6Q-RY2A LG PLC POWER SUPPLY MODEL : GM6-PAFB LG PLC CPU MODEL : K3P-07AS LG PLC TRANSISTER OUTPUT MODEL : G6Q-TR2A MEAN WELL POWER SUPPLY MODEL : S-200-24 INPUT : 1PH AC 115V / 230V OUTPUT : DC 24V 8.5A 200W MEAN WELL POWER SUPPLY MODEL : SP-300-27 OUTPUT : DC 27V 11A 300W MEAN WELL POWER SUPPLY MODEL : S-400-36 OUTPUT : DC 36V 11A 400W MELEC 5-PHASE MOTOR DRIVER MODEL : KP1175-2 MODEL : DB-5410 MELEC STEPPING MOTOR DRIVER MODEL : D-5600 INPUT : 1PH AC 100V MELEC STEPPING MOTOR DRIVER MODEL : SD-200 MELEC STEPPING MOTOR DRIVER MODEL : D-5520 INPUT : 1PH AC 100V MELEC 5-PHASE MOTOR DRIVER MODEL : KP1339 MELEC STEPPING MOTOR DRIVER MODEL : AD-5610 INPUT : 1PH AC 100V ~ AC 115V MELEC STEPPING MOTOR DRIVER MODEL : D-5400 MELEC MOTOR DRIVER MODEL : SD-100 MELEC PCB KP1179-2 C-860A MELEC 5-PHASE MOTOR DRIVER MODEL : KP5027-1 MELEC 5-PHASE MOTOR DRIVER MODEL : KP1340 MELEC STEPPING MOTOR DRIVER MODEL : H-545 INPUT : 1PH AC 100V MELEC STEPPING MOTOR DRIVER MODEL : D-5410 INPUT : 1PH AC 100V MELEC STEPPING MOTOR DRIVER MODEL : AD-5410 INPUT : 1PH AC 100V ~ AC 115V
