今在學(xué)習GX-DEVELOPER時(shí)遇到幾個(gè)不懂的地方:MELSECNET,  MELSECNET 10,  MELSECNET 11,
MELSECNET H,  MELSECNET MINI  具體有啥不同, 
232與485結構有啥不一樣的,用途?,大學(xué)里學(xué)的都忘掉了,還有什么9針與25針的?
學(xué)如逆水行舟, 不進(jìn)則退

MELSECNET 11沒(méi)有聽(tīng)說(shuō)，應是MELSECNET Ⅱ吧

都是三菱的MELSECNET網(wǎng)的一種。
MELSECNET/10和MELSECNET/H都用過(guò)，其他的太老了。
