Diagnostic tab

This page has information about the hardware status (e.g., storage space, memory, CPU temperature) and errors and alarms.

Errors and Alarms

The Errors and Alarms tab and the 7-segment display shows controller errors or alarms generated by the system.

Controller

Description

Storage Space

This is 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 is the amount of RAM memory available on the Controller.

CPU Usage

This is the current load on the CPU.

  • If the load goes over 90%, the field turns red.
  • AKD PDMM and PCMM: CPU usage is the average of all the cores.
  • PCMM2G: CPU usage is measured across the CPU cores that run the motion engine and PLC program.

CPU Temp

This is the temperature of the CPU in Celsius.

  • If the CPU temperature is greater then the CPU warning limit, the temperature background color changes to yellow.
  • If the CPU temperature is greater than the CPU critical temperature, the temperature background color changes to red.
  • PCMM: The normal operating range is 0 °C to 125 °C.
  • PCMM2G: The normal operating range is 0 °C to 81 °C.

CPU Fan Present

This is either True or False, depending if there is a CPU fan present in the controller.

Refresh

Click this button to refresh the Hardware Status information.

Reboot

Click this button to reboot the web server.

  • A common error or alarm is due to the flash memory being full.
    This is often caused by heavy use of the PLC Advanced File function blocks.
    Some errors or alarms are only cleared by powering off and restarting the Kollmorgen controller.
  • The Refresh button updates the list.
  • The Clear button removes the contents of this tab.

See Controller Error and Alarm Descriptions for a complete list of codes.


  • Axis errors can be seen in the KAS Application Axis tab.

Hardware Status


  • Do not try to refresh the web page until the server has rebooted.

Crash Reports

The files shown on the Crash Reports tab are reports of the process that failed if there is a crash.


  • These archives may be sent to Kollmorgen for analysis:
    .GZ for AKD PDMM and PCMM (AKD PDMM and PCMM image)

    .ZIP for PCMM2G (PCMM2G image)
