Upgrading firmware M340-P34 2020 currently on version 2.20

[tiago_angelo]

Good evening,

I have 3 M340 P34 2020 PLC's running on the version 2.20 - 8

PLC RANGE: Modicon M340
PROCESSOR NAME: BMX P34 2020
PROCESSOR VERSION: 02.20 - 8
HARDWARE ID: 1030106

I have read all the firmware update docs, and one seem to refer to any limitation in hardware revisions, can I just update them all to the latest firmware?

I have already migrated the projects from Unity Pro XL V7.0 to the latest Control Expert Classic, but I'm using a test PLC that is already on the latest firmware version.

Best regards.

Replying for anyone with the same doubt.

Using Unity Loader V14 I have successfully updated 3 PLCs to the latest firmware available at this date (version 3.6) without any issue. One I updated to the V3.50 first, the other two I went straight to the 3.60 firmware.
