KLA-Tencor 2214-30SLQTC 進(jìn)口氬激光器備件
內(nèi)部繼電器數(shù)，有的稱為標(biāo)志位數(shù)，代表著PLC的內(nèi)部繼電器數(shù)。2214-30SLQTC與I/O繼電器區(qū)相聯(lián)系著，有時與后者相聯(lián)系進(jìn)行處理。內(nèi)部繼電器多，便于PLC建立復(fù)雜的時序關(guān)系，以實(shí)現(xiàn)多種多樣的控制要求。一般講，內(nèi)部繼電器數(shù)比I/O繼電器要多得多。
有的內(nèi)部繼電器還可丟電保持，即它的狀態(tài)（ON或OFF）、PLC丟電后，靠內(nèi)部電池仍予以保持。再上電后可繼續(xù)丟電前的狀態(tài)。保持繼電器可增強(qiáng)PLC控制能力，特別對記錄故障，故障排除后恢復(fù)運(yùn)行，更顯得有用。定時器，可進(jìn)行定時控制。定時值可任意設(shè)定。定時器有多少，設(shè)定范圍有多大，設(shè)定值的分辨率又是多少，這些都代表定時器件的性能。計(jì)數(shù)器，可進(jìn)行計(jì)數(shù)，到達(dá)某設(shè)定計(jì)數(shù)值可發(fā)送相應(yīng)信號?？蛇M(jìn)行什么樣的計(jì)數(shù)，計(jì)數(shù)范圍多大，怎么設(shè)定，有多少計(jì)數(shù)器，則是PLC計(jì)數(shù)器性能的代表指標(biāo)。
數(shù)據(jù)存儲區(qū)，用以存儲工作數(shù)據(jù)。2214-30SLQTC多以字、兩字或多字為單位予以使用，是PLC進(jìn)行模擬量控制，或記錄數(shù)據(jù)所必不可少的。這個存儲區(qū)的大小代表PLC的性能也是越大越好。趨勢也是越來越大。小型機(jī)也如此。如日本OMRON公司的CQM1機(jī)，其DM區(qū)就有6k字。而過去同是小型機(jī)的C60P的DM區(qū)才64個字。大型機(jī)的DM可達(dá)10K以至幾十K。
The number of internal relays, some of which are called flag digits, represents the number of internal relays of 2214-30SLQTC. It is associated with the I / O Relay area and sometimes with the latter for processing. There are many internal relays, which is convenient for PLC to establish complex timing relationship to realize a variety of control requirements. Generally speaking, there are many more internal relays than I / O relays.
Some internal relays can also be maintained after power loss, that is, its state (on or off) and 2214-30SLQTC can still be maintained by internal battery after power loss. The state before power loss can be continued after power on. Holding relay can enhance PLC control ability, especially for recording faults and recovering operation after troubleshooting.Timer for timing control. The timing value can be set arbitrarily. The number of timers, the setting range and the resolution of the setting value all represent the perbance of the timing device.
