Fault

[ypf_108]

This subroutine L0.0 when set?

 

[L D[AR2P#0.0]]

L0.0 will be true when the rack fault occurs. OB86 will also get called when the rack fault clears but this time L0.0 will be false.

How to determine is the L0.0 do? thanks
I just started learning S7-300,My project S7-300 DP PROFIBUS 6se71.

How to determine is the L0.0 do? thanks

Highlight OB86 in the blocks folder and press F1 for the Siemens help.

That is just the S7-300 rack, not the inverter the 6SE71 of PROFIBUS failure? This fault me how to troubleshoot it?

 

[L D[AR2P#0.0]]

That is just the S7-300 rack

Where did you read that ?

Here's my help:

 

[ypf_108]

OB86_EV_CLASS OB86_FLT_ID Meaning
B#16#39 B#16#C1 Expansion rack failure?OB86_MDL_ADDR: Logical base address of the IM?OB86_Z23: Contains one bit for each possible expansion rack: Each expansion rack that caused a call of OB86 is reported as having failed (the respective bits are set). Expansion racks that previously failed are no longer shown.- Bit 0: always 0- Bit 1: 1st expansion rack- :- Bit 21: 21st expansion rack- Bit 22 to 29: always 0- Bit 30: Failure of at least one expansion rack in the
SIMATIC S5 area- Bit 31: always 0
For example, this type do you mean?

My station is just a rack

 

[RMA]

L0.0 TRUE means that either a remote Station has been disabled using SFC 12 - OB86_EV_CLASS = 16#33 - or that a rack fault has occurred - OB86_EV_CLASS = 16#39 - and the error type and rack number are held in OB86_FLT_ID.

How I read the OB86_FLT_ID?
