Note that firmware versions as of V3 cannot be loaded on CPs with hardware product
version 1.
There are three different ways of loading a new firmware file on the CP:
● Saving the firmware file on the memory card of the CPU
You will find a description of the procedure for loading on the memory card of the CPU on
the Internet page of Industry Online Support shown above.
● Loading the firmware with the online functions of STEP 7 via a WAN
● Downloading the firmware via the Web server of the CPU (as of CPU firmware version
V4.0)
You can recognize that firmware is being loaded by the flashing LEDs of the CP, see section
LEDs (Page 28).
The last two methods are described below.
