Diagnostic (PDMM and PCMM Only)
This page displays information about the hardware status (storage space, memory and CPU temperature) and errors and alarms.
Errors and Alarms
Any controller errors or alarms generated by the system will be shown here and on the 7-segment display. A common error or alarm is due to the flash memory being full. This is often caused by heavy use of the PLC
"Programmable Logic Controller"
A Programmable Logic Controller, PLC, or Programmable Controller is a digital computer used for automation of industrial processes, such as control of machinery on factory assembly lines.
Used to synchronize the flow of inputs from (physical) sensors and events with the flow of outputs to actuators and events Advanced File function blocks.
The Refresh button updates the list. The Clear button will remove the contents of this tab. Please note that some errors or alarms are only cleared by powering off and restarting the AKD PDMM or PCMM.
See Errors and Alarms for a complete list of codes.

Axis errors can be seen in the KAS Application Axis tab.
Hardware Status
| Storage Space | The diagnostic displays both the used and total available amount of storage space in megabytes (MB). Used is the amount of file space currently being used by all files in flash memory. Total is the total amount of file space available for files in flash memory. |
| Available Memory | This field displays the amount of RAM memory available on the Controller. |
| CPU usage | This field displays the current load on the CPU. For dual-core systems, this is the average of the two cores. If the load goes over 90%, the field turns red. |
| CPU Temp | This field displays the temperature of the CPU in Celsius. If the CPU temperature is greater then the CPU warning limit, the temperature background color will be changed to yellow. If the CPU temperature is greater than the CPU critical temperature, the temperature background color will be changed to red. The normal operating range is 0-125°C. For dual-core systems, this value is the average of the two cores. |
| CPU Fan Present | This field is either True or False, depending upon if there is a CPU fan present in the controller. |
| Refresh | Clicking this button will refresh the Hardware Status information. |
| Reboot | Clicking this button will reboot the web server. |

Crash Reports
The files shown on this tab are reports of the process that failed if there is a crash. These files (GZ archives) may be sent to Kollmorgen for analysis.
