Backup & Restore from the Web Server
These functions are used to replicate a AKD PDMM or PCMM (Backup and then Restore) to or from the SD card. The elements that are backed up or restored are the firmware, the network configuration, the Retain Variables, and 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 application.
- These functions cannot be performed while an application is running.
- Restore and Backup take several minutes to complete. Do not power off the control once started.
- The Controller is rebooted after a Restore.
The AKD PDMM and PCMM are available with different CPU variants (800 MHz, 1.2 GHz single core, and 1.2 GHz dual core). The AKD PDMM and PCMM models have the same functionality, but due to the CPU speed differences an application designed for the 1.2 GHz model may not execute as expected on the 800 MHz model. Additionally, an application designed for a single core CPU model may not execute as expected on the dual core model. The Restore will not allow a higher speed model to be replaced with a lower speed model. The Restore will 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.
| Backup File Source | 800 MHx Restore | 1.2 GHz Single Core Restore | 1.2 GHz Dual Core Restore |
|---|---|---|---|
| 800 MHz Backup | Yes | Yes - If 1.2 GHz Runtime file is included in the Backup | No |
| 1.2 GHz Single Core Backup | No | Yes | No |
| 1.2 GHz Dual Core Backup | No | No | Yes |
