ABB plc upload
i have a AC800-PM851 and AC500-PM582 PLC in my site. Is it possible to upload the LAD logic from AC800 and AC500 series PLC, Memory card are not inserted in it.
No and No
For the AC500 PLC the source code *should* be stored on the SD card, but this is not always true. If the source code is saved on a card then it is possible to copy it back to the programming PC.
For the AC800 the source code cannot be stord on the memory card and it is not possible to upload source from the PLC at all.
You will need to get the source code for both PLCs from the original programmer.
For the AC500:(from the Automation Builder help menu)
The menu items "Sourcecode upload" and "Sourcecode Download" are accessible via right click on context menu of the PLC node in Automation Builder tree.
The source code downloads and stores the complete actual project as a Zip-file with all necessary files on the PLC’s SD card .The source code upload retrieves a previously downloaded project from SD card to a selectable directory on the Automation Builder PC and optionally opens Automation Builder with this uploaded project. Internally both these commands are invoking a hidden instance of CODESYS V2.3 which is then working in batch mode to accomplish the download/upload. This is important to know for troubleshooting: most of the error messages which could occur during the process are raised by CODESYSV2.3 and will then be displayed in Automation Builder as a result message box (the language of the message box is the installed language of CODESYS V2.3, the messages are sometimes quite "basic").
Before using these commands the following checks should be done to get a successful operation:
- No CODESYSV2.3 instance started from within Automation Builder on the same PLC node should be running.
- To perform the download/upload, CODESYS V2.3 must be able to login to the PLC .Therefore the gateway settings should be correct and saved to project file. It is recommended to test once the ability of CODESYS V2.3 to login to the PLC.
- A formatted SD card must be mounted in the PLC’s SD card slot.
