Ok I'll try a different angle of attack.
I have acquired an S7-1212c unit.
It is just too new for my TIA portal, which is V 15.1
The new PLC I have has firmwear 4.5 the TIA portal I have only supports 4.3, I get some errors regarding synconization etc. and it's like there are some tins that don't work.
how do I update the TIA portal to the correct firmware
