Another techincal question/answer session from our GE PLC Specialists:
Question: The PLC Battery died over shutdown. The electrician had to reload the program. The re-loaded program didn't have the register values. I don't think I know all I should know about saving programs in Cimplicity ME. Can you put me in touch with and ME subject matter expert?
Answer: When you are online with a PLC, and you want to make a backup that will include the register values, you should go to the top level menu Target, and under this select Upload “Target1” from Controller (Note- if you have renamed the Target, the name will show in the “ “). When you click on upload, a pop-up window will give you options to select of Hardware Configuration and Motion, Logic, and Initial/Forced Values. All of these selections should be checked to get a complete upload. The Initial/Forced Values selections will make sure that the register values are uploaded. After the upload is complete, you can go offline and close the project using the File-Close Project command. If you choose to you can then use the File – Backup Project to put the project into a zip file tat can be easily stored or transferred.
From this point, if you want to load the project to a PLC, you would open the project, go online with the PLC, and with the PLC stopped, select the Target – Download “Target1” to Controller . This will pop up an options window, where you can select Hardware Configuration, Logic, and Initial/Forced values. If you choose all of these, after the download is completed the register values will contain the values from your backup.
