10.6 General system failure indication

In case of system failure the “selftest area” in the busmaster picture is used to indicate the failure.

Figure 10-41: Example: Busmaster A with system failure

Possible indications of failure:

File Sys Failure

Failure in the busmaster internal file system detected

INI File Failure

Plausibility check failure of

“Master.ini” file detected

PCL File Failure

Plausibility check failure of “Master_Bus*.pcl” file detected

RAM Chk Fail

Busmaster RAM failure

ROM Chk Fail

Busmaster ROM failure

Fuse Blown

One ore more power loop supplies are not available

Watchdog Reset

Busmaster starts after watchdog reset
