描述
舉個(gè)小例子。假如你會(huì)plc編程,你再遇到一些老的設(shè)備,你不用再去維修,和領(lǐng)導(dǎo)申請(qǐng)一下,直接用PLC改掉,既簡(jiǎn)單又快捷,使設(shè)備比原來(lái)性能更好,這樣既可以使老設(shè)備重?fù)Q新生,又會(huì)得到領(lǐng)導(dǎo)的賞識(shí),你才有加薪的機(jī)會(huì),才會(huì)有談薪的資本。學(xué)會(huì)PLC也意味你會(huì)有更多的就業(yè)機(jī)會(huì)。也許會(huì)有人會(huì)說(shuō),用PLC改會(huì)費(fèi)用很高,其實(shí)不是,近年隨著國(guó)產(chǎn)PLC的大量出現(xiàn),PLC的價(jià)格已經(jīng)很低廉了,國(guó)產(chǎn)PLC價(jià)格約為進(jìn)口PLC價(jià)格的三分之一。有時(shí)候用PLC裝設(shè)備的電箱甚至比傳統(tǒng)的電氣裝還要便宜。假如一套設(shè)備用幾個(gè)時(shí)間繼電器,用幾個(gè)中間繼電器,也要幾百塊錢,差不多也就是一個(gè)國(guó)產(chǎn)PLC的價(jià)格了。而用PLC裝會(huì)更簡(jiǎn)單,性能會(huì)更好。
