The multi download tool can be used to update multiple PLCs with firmware or an application at the same time.
The PLC firmware can be updated via Automation Builder.
This is also necessary for commissioning CPUs.
A very new CPU has no pre-installed firmware. To guarantee the authenticity of delivered AC500-eCo firmware, V3 CPUs are delivered with a boot loader only. You need to download a valid firmware to the CPU. After download, the functionality of the CPU is given.
An Automation Builder project with an AC500-eCo V3 CPU is open.
CPU is in "stop" mode without firmware.
The power LED is ON.
For new modules: IP address is set. (The default IP address is 192.168.0.10)
