Hi lordgalen, In the Following Link it is mention. Downgrading to an older firmware version: In the case of a CPU417-4H (order no. 6ES7 417-4HL01-0AB0) with test date R, S or T, a downgrade can be performed to not lower than version V3.0.0. You can identify the test date by the yellow test label on the rear side of the module. The test date is in the second line under SIEMENS/TESTED, behind VP. If a downgrade is required for your installation and the above restriction is applicable, please contact your local Siemens office. I know you are using the CPU 414H ..... can you tell me why you want to Downgrad the Firmware ? |
