How source code generate in AC1131...??
The controller is programmed with CoDeSys
Newer versions of the controller are called AC500 and use Control Builder Plus
You CANNOT download the source code from the controller. You must get the source code from the original programmer.
I cecked again the manual for AC1131. Maybe it is possible to get a copy of the source if it is saved on the PLC ......
"To upload a project file from the PLC, press PLC at Open project from PLC. You will obtain, as next, the dialog Communication parameters (see menu Online‘ ‘Communication parameters‘) for setting the transmission parameters when no connection exists yet to the PLC. Once an on-line connection has been created, the system checks whether the same named project files already exist in the directory on your computer hard disc. When this is the case you receive the dialogue Load the project from the controller where you can decide whether the local files should be replaced by those being used by the controller. (This sequence is the reverse of the sequence of 'Online' 'Load source code', with which the project source file is stored in the controller. Do not confuse with 'Create Boot project'!)"
Note, if the source code is not saved on the PLC, then you cannot re-create the source from the boot project.
