Hi everyone

I just got an S7-1200 (1214C AC/DC/RLY  214-1bg40-0xb0)

It does not have any memory card. when i tried to download a program it said "the memory card is write protected". and in the " Load Result" area of TIA it shows this message

loading of the hardware configuration failed (0050 79 2 2458). Please check the diagnostic buffer of the cpu. the download aborted afterwards.

I'm using TIA V14 SP3

Please help.

remove the write protection of the card

the card have a small slider which set or unset the writeprotection

sometimes you insert the card the slider will be put to lock and not stay on unlock

thanks for the reply.

i does not have any memory card. and i think cpu-1214c does not require one for loading a program.

Online & Diagnostics---> memory---> program and system memories are shown, but load memory is "In-Evaluable" 

I think i've got a faulty cpu.
