Dear arunvt1992, Let me try to assist you. 1. Can you try to go simatic manager -> plc -> edit ethernet node -> Browse, can you see your own plc? if yes, try to go to the plc, simply press ctrl+I (operating mode), can you monitor the plc operating mode or a dialog box popped out to request for the IP ? choose the correct IP to view to PLC network. 2. Version cross manager is to compare two projects or xml files. I think you can compare the online blocks by clicking the compare block in the block under s7folder. Normally, my practise is to open a chart, press test mode. If you can monitor online directly without any dialog box pop out, it means the chart/program are exactly the same. if there is dialog box popped out, that means the blocks are different/values are different. Then you can check the date of compilation and download using cross reference or OS / CFC log files. |

Dear Arunvt1992, “I am able to go online with the FB,FC,DB. When i compare the ob blocks it shows there are no deviations. The problem is only with the charts.” I never faced this kind of issue before. Normally if you can monitor Blocks, you can monitor charts as well. Can you show me you installed softwares? program->siemens automation-> installed softwares. And, can you make screenshots on your findings/error and put it here? "Also after i go into a cfc chart and give CPU>compare for time stamp comparison thedownload date is same with respect to the available backup on the ES but the "Last online program change " alone is done at a later stage( after 2 months ) .Is this the reason i am not able to go online in cfc" Means the available backup is not the latest version? Use the current one then? Any screenshot? “Should i check the log files this way.. Options>Charts>Logs.” Yes, this is the CFC / CPU logs. "How to check using cross references and os log files..Can you help me on this.." Go to the OS project in Simatic Manager-> Go to Any Simatic PC Station-> go to its corresponding OS - > right click on them-> display compilation log or display load log.

Dear Jaztai, Please find attached document containing the requested snapshots of the errors and logs. With the available backup on the ES i am not able to go online to the CPU. From the OS log i could see it is complied on the same day (15/5/18). AttachmentSnapshots.doc (154 Downloads) |

Dear arunvt1992, In the third pictures, it showed that you have a connection with your PLC/AS project but the project that you are trying to online with is mismatched with the one downloaded in the PLC. It means, your project is not the latest one. Are you sure you have only one 15/5/2018 project? Try to press Open, are you able to find any multiproject/user project beside yours one? I think there should be one master project in the engineering station. If not, then the only option to continue is full download your current project with PLC Stop and all changes between your version and the online version will be gone. All runtime data will be replaced by offline data. Extra, there is a warning in the local data requirement. Click on the Chart Reference data->local data to see what happened there? Attached with a picture. |

In the snapshots of online error when i set the cpu to test mode ,and select a block and click "watch on" i am able to monitor the values in the cfc.Does that mean i am online to the plc or how this test mode works. |

Yea, you can monitor the project for sure. That message is not an error. It is a standard message to put CFC in test mode if your project is not the latest project. If you download that project, it will cause a full download. After full download, since you are using OB35, the system will be able to calculate the local data requirement for OB35. The only way to prevent a full download is, find the latest downloaded project. |

Hello arunvt1992, Let me give you my takes: 1. Screenshots all the screens in HMI as much as you can, all parameters, all equipments. This is to prevent any unforseen situations happened after the full download. May be a valves suddenly claimed that no communication after download? then you can show them the proof saying that the valves were no communication before the download. These goes to all parameters including the process mode. 2. Do a readback in all CPU you have. Chart-> Readback. For safety PLC, be-mindful. Sometimes I prefer to leave the Safety PLC in its original state instead of readback version. 3. you can do a hardware configuration Online Screenshot if you want. 4. Do an Archive before Readback, after readback. 5. If you wanna update some function blocks/ library, do now. 6. Full Compile 7. Full Download. 8. Compare and check everything again. |
