I am trying to upgrade an old Siemens S7-1200 PLC that has a program on in written in version 13 of TIA Portal.
I am going to write a totally new program in Version 16 and download it to the PLC.
I have started a new program in TIA:
- added a new generic S7-1200 and detected the PLC info with no issues
- my computer and the PLC are on the same subnet.
- PLC shows up when I ask to go online in says Connection to PLC_1 terminated
How do I go online and overwrite a program written in version 13?
thanks in advance.....
