RELANCE 57552-4 伺服驅(qū)動器
軟件報錯，如何處理?
軟件組態(tài)與硬件協(xié)調(diào)有誤出現(xiàn)的問題
數(shù)據(jù)庫點組態(tài)與對應(yīng)通道連接的現(xiàn)場信號不匹配;
鼠標驅(qū)動程序加在COM1口，造成系統(tǒng)在線運行時不能用鼠標操作;
打印機不打印等等。
5、連線接頭改注意哪些問題?
連線接頭問題
連接頭沒有采用壓焊或焊接不好造成虛焊;
熱循環(huán)使接頭松動;
螺栓連接點因震動引起松動;
連接點因腐蝕而接觸不良。
當某一生產(chǎn)狀態(tài)異?；驁缶瘯r,我們可以先找到反映此狀態(tài)的儀表,然后順著信號向上傳遞的方向,用儀器逐一檢查信號的正誤,直到查出故障所在。
當出現(xiàn)較大規(guī)模的硬件故障時，最大的可能是由于DCS系統(tǒng)環(huán)境維護不力而造成的系統(tǒng)運故障，除當時采取緊急備件更換和系統(tǒng)清掃工作外，還要及時和廠家取得聯(lián)系，由廠家專業(yè)技術(shù)支持工程師進一步確認和排除故障。
結(jié)束語對于DCS系統(tǒng)的維護工作,關(guān)鍵是要做到預防第一,作為系統(tǒng)維護人員應(yīng)根據(jù)系統(tǒng)配置和生產(chǎn)設(shè)備控制情況,制定科學、合理、可行的維護策略和方式方法,做到預防性維護、日常維護緊密配合,進行系統(tǒng)的、有計劃的、定期的維護,保證系統(tǒng)在要求的環(huán)境下長期良好地運行,使生產(chǎn)過程控制平穩(wěn)、運行穩(wěn)定,為實 現(xiàn)生產(chǎn)和效益的目標,提供可靠保證
After a malfunction occurs, the fault maintenance system should undergo passive maintenance, mainly including the following tasks: 3.3.1 Professional maintenance generally requires the manufacturer or a maintenance engineer designated by the manufacturer to carry out maintenance.
3.3.2 General Maintenance of Users The daily maintenance carried out by the system users themselves should have a certain understanding of the technical difficulty and operability of system maintenance, understand the maintenance tools that should be available, clarify which tasks can be completed on their own, and have a clear understanding. If problems arise, feasible maintenance plans should be formulated in a timely manner. The key to maintaining DCS system faults is to quickly and accurately determine the location of the fault point. Some experiences in fault maintenance can be summarized as follows:
DCS systems often have rich self diagnostic functions. Based on the alarm, the fault point can be directly identified, and the maintenance results can also be verified by eliminating the alarm.
2) Poor contact of communication connectors can cause communication faults. After confirming poor contact of communication connectors, tools can be used to redo the connectors; If the communication line is damaged, it should be replaced in a timely manner.
3) The flashing fault light of a certain card or all data on the card being zero may be due to incorrect configuration information, the card being in a standby state with redundant terminal connection wires not connected, the card itself malfunctioning, or the lack of configuration information in that slot.
During maintenance, the power supply and grounding systems should be checked to ensure they meet the requirements.
(6) Timely maintain DCS maintenance records during major repairs.
2. System maintenance steps during major repairs
Step 1: Check the proofreading backup
Check if the software backup, configuration file backup, control and process data backup are correct and complete.
Step 2: Cut off the power supply in the following order
(1) After each operation station exits the real-time monitoring and operating system in sequence, turn off the power to the industrial control computer and display of the operation station;
