（4）定時(shí)/計(jì)數(shù)器（TIM/CNT） 在CPM1A系列PLC中提供128個(gè)定時(shí)/計(jì)數(shù)器，使用時(shí)，某一編號(hào)只能用作定時(shí)器或計(jì)數(shù)器，不能同時(shí)既用作定時(shí)器又用作計(jì)數(shù)器，如已使用了TIM001，就不能再出現(xiàn)CNT001，反之亦然。
此外，在CPM1A系列PLC中，對(duì)于上述繼電器編號(hào)，也可以用來進(jìn)行高速定時(shí)（又稱高速定時(shí)器TIMH）和可逆計(jì)數(shù)（又稱可逆計(jì)數(shù)器CNTR），它們?cè)谑褂脮r(shí)需要用特殊指令代碼來指定。
（5）內(nèi)部專用繼電器（SR） 內(nèi)部專用繼電器用于監(jiān)視PLC的工作狀態(tài)，自動(dòng)產(chǎn)生時(shí)鐘脈沖對(duì)狀態(tài)進(jìn)行判斷等。其特點(diǎn)是用戶不能對(duì)其進(jìn)行編程，而只能在程序中讀取其觸點(diǎn)狀態(tài)。
CPM1A系列PLC中常用的15個(gè)專用繼電器及它們的具體編號(hào)和功能如下：
25200繼電器：高速計(jì)數(shù)復(fù)位標(biāo)志（軟件復(fù)位）。
25208繼電器：外設(shè)通訊口復(fù)位時(shí)僅一個(gè)掃描周期為ON，然后回到OFF狀態(tài)。
25211繼電器： 強(qiáng)制置位/復(fù)位的保持標(biāo)志。在編程模式與監(jiān)視模式互相切換時(shí)，ON為保持強(qiáng)制置位/復(fù)位的接點(diǎn)；OFF為解除強(qiáng)制置位/復(fù)位的接點(diǎn)。
25309繼電器：掃描時(shí)間出錯(cuò)報(bào)警。當(dāng)PLC的掃描周期超過100s時(shí)，1809變ON并報(bào)警，但CPU仍繼續(xù)工作；當(dāng)PLC的掃描周期超過130s時(shí)，CPU將停止工作。
25313繼電器：常ON繼電器
25314繼電器：常OFF繼電器
25315繼電器：第一次掃描標(biāo)志。PLC開始運(yùn)行時(shí)，25315為ON一個(gè)掃描周期，然后變OFF。
