PCU Hardware Diagnostics
Purpose
The PCU hardware supports the diagnostics of important system components via an
integrated "safecard", which is designated as a Safecard-On-Motherboard (SOM).
These diagnostic functions are only evaluated by systems with HMI Advanced. The fault
statuses of the hardware are reported in the form of alarms via the operator interface of HMI
Advanced. This allows for visualization of the data in HMI Advanced and external evaluation.
Monitored Parameters
The following physical parameters of the PCU 50.3 hardware are monitored:
●
CPU temperature
●
Housing temperature
●
I/O chip temperature
●
Speed of the two housing fans
●
S.M.A.R.T - status of the hard disk
Logging errors without HMI Advanced
The PCU hardware monitor logs all hardware errors in the Windows event log so that the
errors can be output even for a PCU without HMI software being installed.
The alarms are output in the log under "Control Panel" → "Administrative Tools" → "Event
Viewer".
Note
The PLC interface of HMI Advanced is located in DB 10 of the PLC program and is supplied
by the PCU hardware monitor in the event of a failure.
