Freelance Controller(AC900F) redundancy issue!
We have two AC900F controller working redundancy as well as profibus line redundancy and CI840 as redundancy with non-redundant I/O's. Follwing steps has been taken inorder to make this system work.
1) AC900F both of them set to Redundancy enable.
2) crossover cable conected to eth2 on both controllers.
3) Controller firmware changed on Controller and CI's.
4) Checked Profibus connection and termination.
5) Profibus line redundancy Enable (Freelance engineering).
Line A and B both are helathy. As you can see in the picture. Do both of the Controller needs to be on "Run" after going online with the controller? The status of the Controller in Freelance engineering is "Running.sync".
I plugged off profibus connector form line A of CI840, Line B on CI840 takes over.
Everything is working fine as it should be but don't know why i have all the messages. (please see the attached error messages).
I would highly appreciate if you could tell what i am really missing in the system and things need to be done to get this system working.

Please also confirm in which version you are working?
Meanwhile try with these:-
1. When Controller in Redundant Mode, one controller is in run Mode. Other is on hot standby mode.
2. You need to set Station Time when online, through path in CBF Option-Set System Time and set time 5-6 second after PC time.
3. Please check Network Communication with Controller.
4. System is running in Demo Mode So that Hardkey not found alarm is showing.
5. Check internal battery.
6. Use GSD Based slave instead standart FDT Slave.
you have 6 active alarms. The other alarms are gone already ("-" character in front of the priority).
1st alarm tells you that an operator initialized the AC 900F Controller wich made it boot. If that is ok and was a planned action just acknowledge that alarm and it should go.
2nd and 4th alarm tell you that both AC 900F are missing their batteries or the batteries they have are empty and need to be changed. In case you get a power cut or someone switches off the controllers the configuration will be lost and you have to download the controllers again. So plug in fresh batteries.
3rd alarm tells you that you have a diagnostic message on your S800 slave. Open the System view in DigiVis and drill down to the slave like in pict3.png. Then open the DTM and check for Diagnostic information
5th alarm tells you that you need to set the system time. Use Freelance Engineering to do that
6th alarm is the Operator Station telling you that it doesn't have a hardkey, which is ok if you are testing the system (you run in Demo mode).
All alarms except the last should disappear if you remove their cause and acknowledge the alarm.
Ignore Bansal_vikas7's topic 6. With Freelance you can use both, FDT based slaves as well as GSD based slaves.
