Note
Two MAC addresses
When loading the firmware or commissioning the module, please note that the CP has two
MAC addresses (always consecutive addresses).
The first address printed on the module is for layer 2 communication, the second for the
PROFINET protocol (first address plus one).
Example
The address "08.00.06.93.DA.76" printed on the communications processor is the address
for layer 2 communication. This means that "08.00.06.93.DA.77" is the MAC address for
PROFINET communication.
Eliminating problems
A disruption during the firmware download can lead to an inconsistent status on the module.
Status detection
You can recognize an inconsistent status on the CP as follows:
●
The CP is not accessible with STEP 7/NCM PC (in the SIMATIC Manager/SIMATIC NCM
Manager, select configured PC station in the STEP 7 project > menu command "PLC" >
"Edit Ethernet Node").
●
The red SF LED (group fault) flashes at 2-second intervals.
●
Following a computer restart, all the LEDs of an unused RJ-45 jack light briefly and then
go off again.
Note
Green Link LED
In contrast to the brief lighting up of the LEDs when the computer starts up, the green
Link LED always lights up if a cable is inserted in the RJ-45 jack and a link is also
established.
Troubleshooting
Download the current firmware file, for example "fw16xx-v.v.v.b.b.fwl", to the module again
via the ISO access point.
Confirm the error "Error establishing connection to query the hardware version" with "yes"; in
other words, ignore the error.
To download using the ISO protocol, you require the MAC address printed on the module.
