PPT VISION 661-0337 PPT5200是一個(gè)整體單元，配備電源、CPU主板和單元終結(jié)器。該設(shè)備包含微處理器和RAM、實(shí)時(shí)時(shí)鐘、LED指示燈、啟動(dòng)按鈕和安全的數(shù)字接口。PM891不包含任何內(nèi)置電池PM891具有兩個(gè)RJ45以太網(wǎng)端口(CN1、CN2)用于連接到控制網(wǎng)絡(luò)，以及一個(gè)RJ45串行端口(COM4)。COM4端口被隔離并用于配置工具。PM891支持CPU冗馀以實(shí)現(xiàn)高可用性(CPU、CEX-Bus、通信接口和S800 I/O)。
通訊擴(kuò)展總線(CEX-Bus)安裝在設(shè)備上。CEX總線用于擴(kuò)展帶有通信接口單元的板上通信端口。CEX總線上可以使用冗馀通信接口。CEX總線互連單元BC810用于通過將CEX總線拆分為單獨(dú)的段來提高cex總線的可用性。該單元的光纖模塊總線可用于連接七個(gè)S800 I/O單元群集(每個(gè)單元組成12個(gè)單元)。每個(gè)PM891附帶一個(gè) 的以太網(wǎng)地址，可為設(shè)備提供硬件標(biāo)識(shí)。
because successive production processes often have imitation quantity, imitation quantity control is sometimes called process control.analog quantity is mostly non electric quantity, while PLC can only deal with digital quantity and electric quantity. Everything should be changed between them. There should be sensors to change the analog quantity into several electric quantities. If the electric quantity is not standard, the non-standard electric quantity shall be changed into standard electrical signal through transmitter, such as 4-20mA, 1-5V, 0-10V, etc.
PPT VISION 661-0337 PPT5200 should also be analog b unit (A / D) to change these standard electrical signals into digital signals; Analog output unit (D / a) to change the digital quantity processed by PLC into analog quantity - standard electrical signal.therefore, various operations are required to standardize the conversion between electrical signals and digital quantities. This requires a b understanding of the resolution of the analog unit and the standard electrical signal. For example:
