bCX9640, CX9680, ACX5720 and ACX5740 do not have ACCRestartMode system variable.
The restart mode of the second generation Infinity CX controllers (9640, 9680, 5720/40) is not user selectable.
The second generation Infinity CX controllers (9640, 9680, 5720/40) have a fixed startup sequence as follows:
Warm to Cool to Cold, meaning the controller will ALWAYS first attempt to WARM start, if warm start is not possible the controller will attempt a COOL start, if cool start if not possible the controller will attempt a COLD start.
Controller is re-starting with its RAM memory intact because the controller has remained powered or the memory has been kept by the battery. In this case all the configuration data (points, programs) and run time data (logs, points current values) is restored.
Controller is re-starting with its RAM memory erased or is unable to restore data from RAM for whatever reason. In this case the configuration data only (points, programs) is restored provided it has been previously backed up to flash memory. NOTE: Personnel objects are NOT kept in flash, upon cool start the controller will automatically request a personnel distribution from its access server CyberStation.
Controller unable to warm start or cool start, all configuration and runtime data will be lost. It must be reloaded from CyberStation.
