ICS TRIPLEX 9801工控模塊系統備件
實(shí)時(shí)時(shí)鐘必須輸入正確的時(shí)間和日期，事件記錄器事件才能正確標記時(shí)間/日期。電池支持的內部時(shí)鐘即使在斷電的情況下也會(huì )持續運行。它的精度大約為每月±1分鐘。必須通過(guò)前面板或RS485串行鏈路時(shí)鐘更新命令定期手動(dòng)糾正。如果沒(méi)有與其他繼電器同步的事件發(fā)生的大致時(shí)間足夠，則前面板鍵輸入時(shí)間/日期就足夠了。如果使用RS485串行通信鏈路，則所有繼電器可以保持同步時(shí)間。遠程計算機通過(guò)RS485端口將新的時(shí)鐘時(shí)間預加載到469存儲器中，以連接到通信信道上的每個(gè)繼電器。在計算機廣播（地址0）“設置時(shí)鐘”命令后，系統中的所有繼電器在同一時(shí)刻開(kāi)始計時(shí)。在接收串行命令時(shí)可能有長(cháng)達100 ms的延遲，因此每個(gè)繼電器的時(shí)鐘時(shí)間為±100 ms，±PLC或PC的絕對時(shí)鐘精度。有關(guān)時(shí)間預加載和同步命令編程的信息，請參閱第6章：通信。n串行端口n[ENTER]獲取更多從屬地址：254范圍顯示默認消息?？梢赃x擇1到20條默認消息。多個(gè)默認消息以S1 469 SETUP×PREFERENCES默認消息周期時(shí)間設置點(diǎn)確定的速率自動(dòng)按順序掃描?？梢赃x擇任何實(shí)際值進(jìn)行默認顯示；此外，最多可以創(chuàng )建和顯示五條用戶(hù)可編程消息（消息草稿）。例如，繼電器可以交替掃描電機識別信息、各相電流和最熱定子RTD。默認消息顯示在S1 469 SETUP（設置）×Default messages（默認消息）子組中。使用以下步驟添加默認消息：1。為S1 469 SETUP（設置）passcode（密碼）Enter passcode for ACCESS（進(jìn)入密碼）設定點(diǎn)輸入正確的密碼（除非密碼已輸入或密碼為“0”，否則會(huì )破壞密碼安全功能）。2.使用和鍵移動(dòng)到要添加到默認消息列表的消息。所選消息可以是任何實(shí)際值或消息草稿消息。3.按下。消息PRESS[ENTER]TO ADD DEFAULT MESSAGES（按下[ENTER]TO添加默認消息）將顯示5秒。4.在顯示時(shí)再次按下可將當前消息添加到默認消息列表中。5.如果正確遵循程序，將顯示以下閃爍信息：
?× REAL TIME CLOCK The correct time and date must be entered for event recorder events to be correctly time/date stamped. A battery backed internal clock runs continuously even when power is off. It has an accuracy of approximately ±1 minute per month. It must be periodically corrected manually through the front panel or via the RS485 serial link clock update command. If the approximate time an event occurred without synchronization to other relays is sufficient, then entry of time/date from the front panel keys is adequate. If the RS485 serial communication link is used, then all the relays can keep synchronized time. A new clock time is preloaded into the 469 memory via the RS485 port by a remote computer to each relay connected on the communications channel. After the computer broadcasts (address 0) a "set clock" command, all relays in the system begin timing at the same instant. There can be up to 100 ms of delay in receiving serial commands so the clock time in each relay is ±100 ms, ± the absolute clock accuracy in the PLC or PC. See Chapter 6: COMMUNICATIONS for information on programming the time preload and synchronizing commands. n SERIAL PORTS n [ENTER] for more SLAVE ADDRESS: 254 Range splays default messages. Between 1 and 20 default messages can be selected. Multiple default messages automatically scan in sequence at a rate determined by the S1 469 SETUP ?× PREFERENCES ? DEFAULT MESSAGE CYCLE TIME setpoint. Any actual value can be selected for default display; in addition, up to five user programmable messages can be created and displayed (Message Scratchpad). For example, the relay can alternately scan a motor identification message, the current in each phase, and the hottest stator RTD. Default messages are shown in the S1 469 SETUP ?× DEFAULT MESSAGES subgroup. Use the following procedure to add default messages: 1. Enter the correct passcode for the S1 469 SETUP ? PASSCODE ? ENTER PASSCODE FOR ACCESS setpoint (unless the passcode has already been entered or the passcode is “0”, defeating the passcode security feature). 2. Move to the message to be added to the default message list using the and keys. The selected message can be any actual value or Message Scratchpad message. 3. Press . The message PRESS [ENTER] TO ADD DEFAULT MESSAGES will be displayed for 5 seconds. 4. Press again while displayed to add the current message to the default message list. 5. If the procedure was followed correctly, the following flash message will be displayed:
