Backup and Restore from the Web server

The Backup and Restore functions are used to replicate a Kollmorgen controller.

The controller data is replicated on these storage devices:

• AKD PDMM and PCMM: SD card.
• PCMM2G: USB "Universal Serial Bus" USB is a serial bus standard to interface devices flash drive.

All Controllers

The elements that are backed up or restored for all controllers are the:

• Controller firmware.
• Network configuration.
• 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 Application.
• Retain Variables.
• Shared Directory settings
• User data files.
  • See User Data tab for more information.
• Web server and SSH The Secure Shell Protocol (SSH) is a network protocol for secure data communication and remote command execution. SSH applications are based on a client–server architecture, connecting an SSH client instance with an SSH server. user accounts configuration.

PCMM2G Backup / Restore Only

• Backup:
  • AKD and/or AKD2G firmware packages and their respective drive parameters.
  • EtherCAT ***EtherCAT is an open, high-performance Ethernet-based fieldbus system. The development goal of EtherCAT was to apply Ethernet to automation applications which require short data update times (also called cycle times) with low communication jitter (for synchronization purposes) and low hardware costs network topology.
• Restore:
  • The drive's data and firmware is copied from the USB flash drive to the controller flash when the Restore Controller function is selected.
  • The Restore EtherCAT Devices function should be selected for restoring the data and the firmware of any replaced AKD or AKD2G drives.

The Backup and Restore processes:

• Cannot be performed while an application is running.
• Takes several minutes to complete.
  • Do not power off the controller once started.
• The controller is rebooted after a Restore.

• 
  
• AKD PDMM or PCMM do not allow restoring the controller from the PCMM2G backup.
  PCMM2G does not allow restoring the controller from the AKD PDMM or PCMM backups.

The AKD PDMM and PCMM are available with different CPU variants (800MHz, 1.2GHz single core, and 1.2GHz dual core).

• The AKD PDMM and PCMM models have the same functionality but, because of CPU speed differences, an application designed for the 1.2GHz model may not execute as expected on the 800MHz model.
  • An application designed for a single core CPU model may not execute as expected on the dual core model.
• The Restore:
  • Does not allow a higher speed model to be replaced with a lower speed model.
  • Does allow a lower speed model to be replaced with a higher speed model if the Backup contains the model-specific Runtime In computer science, runtime (or run-time) describes the operation of a computer program, the duration of its execution, from beginning to termination (compare compile time). Within KAS, runtime also refers to the virtual machine that manage the program written in a computer language while it is running firmware file.
