text: <s>[INST] 20 COMM D FW VERSION Summary: ERRORS WHEN CHANGING 20 COMM D MODULE WITH DIFFERENT FIRMWARE [/INST] I'm getting some faults related to PORT 5 adapter on a PF70 with device net adapter 20 COMM D, so after troubleshooting it I decided to change 20 COMM D comms adapter, the one that is installed is a 20 COMM D FW VER 1.007 Ser B and I have a new one FW VER 2.001 Ser B, after installing the new one and downloading the config to it a new fault rise and I wasn't able to clear it, the fault was related to config parameters. When I downloaded the config to this new adapter the HIM asked me for confirmation telling that this was a different version to that I hited the enter button accepting the warning. Then after a cuple os seconds of resetting everything the fault appeared. I put again the old module with no faults. Do I need to have the same FW version to replace the 20 COMM D module? Any help will be must welcome. \\n </s>
