Common system maintenance problems of DCS

Q1：现场新增加一台操作站如何对其进行软件授权?

Q1: how to authorize a new operating station on site?

A： 需购买配备相应权限的硬件软件狗一只，工程师狗或操作员狗。若需oPc通讯连接，软件狗还需具备oPc通讯权限。 Q2：VF软件如何进行组态备份和还原？

A: You need to buy a hardware and software dog equipped with corresponding authority, engineer dog or operator dog. If OPC communication connection is required, the dongle also needs to have OPC communication permission. Q2: how to backup and restore the configuration of VF software?

A： 在结构组态软件中用文件“备份工程”和“还原工程”可分别对服务器组态进行备份和还原操作. Q3：PRo软件如何进行组态备份

A: The server configuration can be backed up and restored by using the files "backup project" and "restore project" in the structure configuration software Q3: how to backup the configuration of the Pro software

A： 打开新组态，点击菜单“总体信息”→“备份数据”，选取备份路径、取名、保存，即可将组态进行备份。注意：本备份操作不包含对监控历史数据的备份（如历史趋势、历史报表等），若还需对监控历史数据进行备份，则将整个组态文件复制到移动存储器即可。

A: Open the new configuration, click the menu "general information" → "backup data", select the backup path, name and save to back up the configuration. Note: this backup operation does not include the backup of monitoring historical data (such as historical trend, historical report, etc.). If it is necessary to backup the monitoring historical data, copy the whole configuration file to the mobile memory.

Q4：如何在组态软件（PRo）上新增加一个位号

Q4: how to add a new tag number to the configuration software (PLO)

A： 有符合类型的备用点时，修改属性，设置报警、趋势服务组态；无备用点时则增加卡件（机笼），添加位号，未用完的通道组备用点（去掉报警）；流程图上加动态数据（开关量）等；位号关联流程图（趋势画面PRo2.65）；然后编译、下载、发布（或传送）。注意：增加Ao 点需要组回路，在线下载时现场需做好相应准备和配合。 Q5：大修后DcS系统如何上电，如何对DcS供电检查？

A: When there are backup points that meet the type, modify the attributes and set the alarm and trend service configuration; When there is no spare point, add the card (cage), add the tag number, and the spare point of the unused channel group (remove the alarm); Add dynamic data (switching value) on the flow chart; Tag number Association flow chart (trend screen pro2.65); Then compile, download, publish (or transfer). Note: adding Ao points requires a group of circuits, and corresponding preparations and cooperation shall be made on site during online download. Q5: how to power up the DCS system and check the power supply of DCS after overhaul?

A：DcS系统对供电质量有一定要求，大修后DcS上电应注意： 1、确认外部供电是否平稳，如检修期间电压不稳不要上电。

A: The DCS system has certain requirements for power supply quality. Attention should be paid to: 1. Confirm whether the external power supply is stable. If the voltage is unstable during maintenance, do not power on.

2、测试外部供电电压是否符合198V-242V要求。

2. Test whether the external power supply voltage meets the requirements of 198v-242v.

3、上电时按先总电源，再操作站，控制柜，外配柜顺序上电(断电则相反)。

3. When powered on, power on in the order of the main power supply, then the operation station, control cabinet and external distribution cabinet (the opposite is true in case of power failure).

4、上电后对DcS卡件故障报警、电压故障报警、交换机和网络检查，对供电电压测试。

4. After power on, check the DCS card fault alarm, voltage fault alarm, switch and network, and test the power supply voltage.

5、用万用表可检查DcS每个机笼的5V、24V电压，如低于5V、24V则不正常。如需对供电质量深入检查，需用示波器或电能质量分析仪检测分析。

5. Use a multimeter to check the 5V and 24V voltage of each cage of DCS. If it is lower than 5V and 24V, it is abnormal. If in-depth inspection of power supply quality is required, oscilloscope or power quality analyzer shall be used for detection and analysis.

专家建议：系统维护负责人确认条件具备方可上电。应严格遵照上电步骤进行。

Expert suggestion: the person in charge of system maintenance can power on only after confirming that the conditions are met. Strictly follow the power on steps.
