PLC控制系統(tǒng)的抗干擾設(shè)計(jì)。隨著工業(yè)自動(dòng)化技術(shù)的日新月異的發(fā)展,晶閘管可控整流和變頻調(diào)速裝置使用日益廣泛,這帶來了交流電網(wǎng)的污染,也給控制系統(tǒng)帶來了許多干擾問題,防干擾是PLC控制系統(tǒng)設(shè)計(jì)時(shí)必須考慮的問題。一般采用以下幾種方式:
A CPU, GE Versamax IC200CPU001, has 2 serial ports, 34kb of configurable memory. The GE Versamax IC200CPU001 has support for 32-bit Modbus registers, updated pid function block, higher serial communications throughout. The GE Versamax has non volatile flash memory for program storage.
