Shutdown on Low Power
VTScada is configured to perform an orderly shutdown when it is able to detect that the workstation is running on battery power (usually an uninterruptible power supply - UPS), and that battery is nearing the end of its charge.
You can control this feature using the following properties within the configuration file Setup.INI in the VTScada installation folder. These allow you to enable or disable the automatic shutdown feature, and when enabled, set a threshold for three different battery indicators, any of which will trigger an automatic shutdown.
Use these settings with care. Some VTScada users have found that in a location with both intermittent main power and faulty status reporting from the UPS, unexpected shutdowns have occurred.
OrderlyShutdown - Enables or disables the feature.
ShutdownOnLowBattery - On or off. When on, and the battery status property indicates "low battery", a shutdown will occur.
LowBatteryPercent - Threshold value. When the remaining battery life, reported as a percentage value, crosses below this value, a shutdown will occur.
LowBatteryTime - Threshold value. When the remaining battery life, reported as a time remaining value, crosses below this value, a shutdown will occur.
