Hi.
I am using TIA Portal 18 in This version of TIA portal inside of TIA Software when I want to select
CPU 1516F-3 PN/DP (6ES7 516-3FN01-0AB0) inside of network over view of TIA portal I can select the firmware version at last 2.9
and also I have checked this selection is same for TIA 19.
one more amazing thing is availability of 2.9 firmware inside siemens formal website for this kind of PLC
But I have bought one PLC that has the firmware as 3.0 version.
and in this case I receive a message in CPU regrading the Mismatch version between offline and online CPU .
does any body can help me to manipulate the CPU Version in TIA portal ?
