REPORT SYSTEM ERORR and FB126

Hello, 

Am usning IM 151-8PN  cpu with STEP75.5 sp4  & TP1200 Comfort panel (v13 sp1) for HMI display. I have enabled "REPORT SYSTEM ERROR" in PLC. I need to get remote station module and remote i/o's module diagnose also. Its working good with RSE + device proxi in HMI+ alarm screen.

1. But i am facing issue like that, if any node removed from profinet network, CPU is going to stop mode even all the error ob are loaded. After warm restart it become ok again.  Diag Buffer shows stop caused by "FB49" (SFM FB). If am removing RSE from project, there is no issue after removing the I/O device from the network. Is it common behavior of RSE or some other parameter i have to taken care ?

2. RSE shows the error details in alarm window. Can i use FB126(PNIO Diag) along with RSE configuration to have better view in hmi ? 

2.1 .For HMI am migrating wincc flexible sample project to tia, is there any alternative ?

3. In RSE also, i can see "diagnose support" tab shows option as "profinet io db", "diagnostic status db" and help file shows this can be used to for HMI visualization. Any document/sample program is available ? Is it same as FB126 ?

4. XML file generated in RSE can be linked to HMI for any visualisation purpose ?

Hi,

The stop mode issue is resolved. It was problem with Rse settings.

Other questions ?

update...

Tested FB126, RSE with step7 + wincc flexible combination. Working ok.

Migrated flexible project to TIA (wincc comfort v13 sp1 upd8), added PLC via device proxi and tested, working ok with 1 problem.

FB126 functionality for the node overview is working ok(tested for profinet)

But with RSE, error is generating, but not showing any error text. If i check the controller message, alarm entries are there, but not showing any text. Tried migration many time, but same result.

Compile also showing the warning about alarm text..
