IPC monitoring: The ‚classic‘ parameters
The three classic parameters that are suitable for simple and effective monitoring are temperatures, speeds of rotation and
voltages on the motherboard: the CPU temperature provides information regarding the extent of processor utilization and the
ventilation quality. Knowing the speed of the fan rotation allows conclusions to be drawn about contamination and possible
wear. A check of the various on-board voltages also ensures the smooth operation of the IPC. In addition, the voltage level of
the frequently existing lithium battery for the system clock can be checked. Apart from these three parameters, checking the CF
cards and RAID systems is important for the trouble-free operation of PC-based controls.
CF card testing tools that require the medium to be removed from the IPC are suitable only in the case of plant standstills,
since removing the card entails switching the IPC off. Online monitoring is more convenient and can be accomplished during
running operation. The degree of use of the CF card is displayed directly by percentage via the diagnostic and configuration
interface for Beckhoff IPCs. Additionally, a message on the screen can suggest a replacement upon falling below a certain limit,
so that an exchange can be considered during the next scheduled maintenance.
RAID systems work in the background and are only visible to the user in the operating system as a logical drive that is not
distinguishable between the individual hard disks. For monitoring purposes the data in the RAID controller can be accessed, via
which the status and the performance of the individual hard disks can be read out. If read/write errors continually occur within
the same sector of a disk, then an exchange should be considered.
