Upgrading Firmware - Siemens SIMATIC ET 200pro FC-2 Operating Instructions Manual

9.3.1

Upgrading firmware

When upgrading firmware you replace the inverter's firmware with a newer version. Only
update the firmware to a newer version if you require the expanded range of functions of that
newer version.
Requirements
1. Your inverter's firmware is at least version V4.7.x.
2. Inverter and memory card have different firmware versions.
Procedure
1. Switch off the 24 V inverter power supply.
2. Disconnect the connectors for power supply and motor from the inverter.
3. Disassemble the inverter and remove it from the ET 200pro station.
4. Insert the card with the matching firmware into the slot on the rear side of the inverter until
you can feel it lock in place.
5. Plug the inverter into the ET 200pro station and tighten two of the fixing screws so that
the inverter can no longer unintentionally become detached from the bus module.
6. Switch on the 24 V inverter supply voltage.
7. The inverter transfers the firmware from the memory card into its memory.
The transfer takes between 5 and 10 minutes.
While data is being transferred, the LED RDY on the inverter stays red. The SAFE LED
flashes with a variable frequency.
