Behavior of the new version:
In the situation described below, the controller reinstalls the firmware (from /sdcard/firmware) and is accessible again via Ethernet after the restart.
Instructions on how to install the firmware on the SD card if it is not available:
Then the SD card of the controller must be inserted into a card reader of the PC and then the firmware must be installed with the EASY Firmware Loader from V1.29.
In the EASY Firmware Loader, select the communication path: Removable medium or PC file system. From version 1.29, the EASY Firmware Loader recognizes that the firmware is to be loaded onto an SD card instead of a USB stick and adjusts the directory accordingly. The firmware file is saved to the SD card as follows
<SD card>/firmware/cxx_v_<version>_firmware.tar
Description of the behavior:
Controller does not start - RDY LED flashes - a connection to the controller via Ethernet with e.g. EASY Starter or EASY Firmware Loader is not possible.
Conditions under which the behavior occurs:
The behavior can occur if the controller is supplied with voltage more than 10 times for only a few seconds and then switched off again.
Further possibilities of how this state can be achieved cannot be named.
Affected products:
Controller c430
Controller c520
Controller c550
Short-term measures, Recommendations, Rating:
If this condition occurs, the controller must be sent to Lenze Service.
Note: Please leave the controller switched on for a few minutes before switching it off again.
