How to update firmware on CP 1543-1?

Bachgeist Posts: 53 Rating: (9)	Hi, how is the procedure to perform a firmware update on a CP 1543 or which possibilities exists? Update of CPU & Display was no problem via "functions" over "online&diagnostics" after connecting. I thought it will be maybe possible over the web-server, but I found nothing about it. Is their an extra tool requiered like the "CP firmware loader" in S7- Classic? Thanks in advance. Greetz Bachgeist

Go online in TIA with the project and open the device view of the station. Select the CP and open the "Online&Diagnostics" of the CP, and here should be the function "Firmware Update" availöable. Regards Christoph
