Web Server Diagnostic

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

Errors and Alarms

The Errors and Alarms tab and on the 7-segment display shows any 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. For multi-core systems, this is the average of all the cores. If the load goes over 90%, the field turns red.
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. 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 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 "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.
  Some errors or alarms are only cleared by powering off and restarting the Kollmorgen controller.
