Firmware Update¶
After pressing “Update Firmware” the following dialog will be shown. It displays the firmware that can be updated. If the CPU firmware version is lower than 2.5.0.0 the CPU firmware must be updated before any Communication Module firmware can be updated.
If multiple firmware types of a device can be updated, all firmware types must be updated in one step, thus selection in column update is possible on device level. Currently multiple firmware types exist only for CPUs.
After pressing “OK” the firmware files are downloaded to the ramdisk of the CPU and the update is triggered. Firmware update is only possible when:
- PLC is in “Stop”.
- The ramdisk has enough free space for the largest firmware file to download plus about one kByte for control files.
- The gateway settings in the IEC 61131-3 editor V2.3 project are correct.
The PLC must be rebooted after the firmware update has been completed. This could be done i.e. by power cycle or with PLC browser command “reboot”.
When updating the CPU firmware from a version below 2.5.0.0 to 2.5.x.x or higher the end of the firmware update can’t be detected automatically. The user must observe the PLC to check that firmware update has been completed before rebooting the PLC. See the documentation for the CPU type on how completion of update is indicated.
